Loctite Lubricants Sealants Adhesives - LT37467

  • Gasket Maker
  • Sealant
  • 2.7 oz
  • Loctite

This black silicone gasket maker forms a high-quality gasket that seals the space between matched parts to prevent leakage of automotive fluids and gases. It meets manufacturers' specifications for original equipment.


Features:

  • Seals joined parts in automotive systems - prevents leakage of antifreeze, air, oil and transmission fluid
  • Meets manufacturers' warranty requirements
  • Resists oil better than other silicone gasket makers
  • Won't interfere with sensors
  • Won't corrode
  • Resists vibration
  • Made in the USA


Specs:

  • Quantity: 2.7-fl oz tube (80 mL)
  • Tack-free cure (time required to dry past tacky state): 30 minutes
  • Full cure (time required to reach full set): 24 hours
  • Temperature range (endurance limits of the gasket maker): -75 F to 625 F
  • Ideal gap-filling capacity (gap sizes in which gasket maker performs best): 0.001" to 0.125"
  • Maximum gap-filling capacity (maximum gap size between joined parts): 0.240"


Applications: Valve covers, oil pans, timing covers, water pumps and thermostat housings



Applied as a gel to just one surface of the parts to be joined, silicone gasket maker forms a seal between them, keeping out contaminants. Silicone gasket maker resists oil and shop fluids, vibration, heat, and flexing of parts, replacing many conventional gaskets. Parts joined by this silicone gasket maker can easily be removed. The old gasket material comes off effortlessly, simplifying future disassembly and reassembly.


Because of their ability to flex and compress, silicone gasket makers work better than other kinds of gasket makers when the parts to be joined are made of different materials, which have different rates of expansion and contraction when temperatures change. They also work better than other types of gasket makers on stamped metal parts that can flex and in situations where clearances can be large.

This went on without a problem on a 2022 Subaru Outback thankfully providing the built-in wiring harness that is located under the right side rear trim piece, I did not need to remove. I used 3M Dual Lock in case the control unit needs to be easily moved in the future. Using this for a OneUp Bike Rack and their license plate and LED light bar.




by:

Works as advertised. Pretty simple install. As usual great quality product(s) from etrailer

Professional installed. Working well after 1 year. Expect it to keep working.

Hasn’t cracked or leaked in a year. Thumbs up!

Originally ordered to close extra holes in a Yakima Rocket Box that required new hardware. Does the job.

I used this to seal the installation holes on my hitch mount. The stuff is very easy to work with and sets up nicely. Work great and provides a great finished seal.
Etrailer had the best price I could find also.

by:

Worked as advertised.




by:

Good stuff. Used on hitch install to get best adherence to frame.




by:

Its loctite... Great product




by:

The carrier performs just as it was designed. Putting the rubber sleeves on was difficult and the sealer has already pealed of . Before I use it again I will put silicone caulk on the joints




by:

I used this to seal the hole I had to drill in my car when installing my hitch to keep water and exhaust out of the cabin, it dried quickly and created a good seal to keep stuff out




by:

works well, be careful on the pressure you apply. I applied too much pressure (i was rushing it) and it went out the back end... complete user error but be warned.

Good product.




by:

i used this product when I put together my cargo carrier. I put it on the bolts before I screwed on the nuts for added insurance to keep the carrier nice and solid.




by:

Used during 2012 VW Jetta TDI sedan hitch and wiring installation (per video recommendation).




by:

This is the perfect RTV for way covers on CNC machines. They seal the coolant out and yet you can get the covers back off without damaging them.




by:

This is the BEST RTV ever.
FAST delivery.
PERFECT transaction!
Thank you etrailer.com for a job well done!!

  • Can You Drill Holes in a Thule Cargo Box to Move it Forward and Clear the Rear Hatch
    Yes, you can drill new holes in your Thule Frontier Cargo Box in order to clear the rear hatch on your 2018 Subaru Outback Wagon. I also recommend using part # LT37467 to cover up the old holes so water doesn't get in. The only thing you need to be aware of when drilling new holes is how you load the cargo box. Since the front of the box is going to be moved further away from the crossbars you will just want to make sure you keep the heavier items towards the rear and centered on the crossbars.

  • Can I use Loctite Gasket Maker On Fuel Tank
    Yes, the Loctite RTV Gasket Maker part # LT37467 will work well as a sealant between the crinkle (or wrinkle coat) paint and the fuel gauges gasket. The sealant forms a high quality gasket to prevent automotive fluid and gas leakage.

  • Yakima Rocketbox Mounting Location Change for Crossbar Fit
    You can drill holes in your Yakama Rocketbox to give you the crossbar fit you need. You will then simply use a sealant like # LT37467 to seal the factory holes so you don't have water issues.

  • Tail Light Gasket for 1999 American Tradition Motorhome
    Unfortunately we don't have a custom fit tail light gasket for your 1999 American Tradition Motorhome. If you are just looking for that watertight seal, I recommend the Loctite RTV 598 High-Performance Silicone Gasket Maker - Black - 2.7-Fl Oz Tube # LT37467.

  • Recommended 2016 Keystone Sprinter Control Box Sealant
    The sealant on the Lippert Control box you referenced is simply a high performance gasket sealant. I recommend the Loctite RTV 598 High-Performance Silicone Gasket Maker - Black # LT37467 as a replacement to keep that box sealed tight from the elements. Keep a wet rag close by when using this as it can be messy and also sticky. It will take only 30 minutes to set but 24 hours to cure.

  • Recommended Parts to Re-Install Lock Mechanism on 1997 Thule Rooftop Cargo Box
    Thule does not supply the cargo box lock mounting rivets as replacement parts; this is because these are not intended to be removed. But you certainly can substitute other hardware, and that does not necessarily even have to be rivets, to re-install the lock assembly on your '97 Thule cargo box. Since this hardware will see some exposure to the elements I suggest that you select stainless-steel bolts, washers and nuts. Your local full-service hardware store should have a decent assortment...

  • Can You Drill Holes in Thule Cargo Box to Fit Shorter Crossbars on 2016 Subaru Crosstrek
    Yes, you can drill new holes in your Thule cargo box in order to mount this on your 2016 Subaru Crosstrek. When you drill the holes you need to make sure you maintain the correct spacing for your existing mounting hardware. After drilling new holes, I recommend sealing the old holes with # LT37467 Loctite RTV 598 High-Performance Silicone Gasket Maker.

  • Is a 2018 Toyota Sienna Factory Wired for Trailer Wiring Harness and Converter?
    For your 2018 Toyota Sienna, the factory wiring harness at the tail lights is the extent of the wiring for trailer connections. This means you can use a T-One wiring harness with a converter integrated, but you will need to run the power wire to your battery. I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118648 as it is consistently the best brand for long term function. I've attached a couple videos to help with installation and have also...

  • How to Attach SuperCush Anti-Sway Cradles 8880598 to Arms on Yakima Little Joe 3 Bike Rack
    The Yakima Little Joe 3 bike carrier is something of a bare-bones bike carrier and so I understand your interest in giving it an upgrade by using the SuperCush Anti-Sway Cradles # 8880598. I measured the rack arm diameter and found it to be 1-1/8-inches; I also measured the hole diameter of the cradles and found that to be 1-1/4-inches. So, the cradle will fit on the rack arm with room to spare. I recommend that you avoid drilling into the rack arms to install the cradles as this might...

  • Is Hardware Included with Draw Tite Hitch for 2020 Volvo XC40
    Actually the Draw Tite hitch for you 2020 Volvo XC40, part # 76245, uses existing M10 flange nuts that are already on your vehicle to install. There isn't any additional hardware that you need. I do recommend getting a tube of sealant like part # LT37467 that gets used to install the hitch. Take a look at the installation video and you'll see where the sealant is used. It also shows the existing nuts.

  • Correct Trailer Hitch for a 2002 Buick Regal
    Yes, the Draw-Tite Sportframe Trailer Hitch Receiver part # 24660 is indeed a fit for a 2002 Buick Regal. The Draw-Tite Sportframe Trailer Hitch Receiver is also a custom fit so no drilling into the frame is required. That said, you will want some gasket maker, the Loctite RTV 598 High-Performance Silicone Gasket Maker part # LT37467 to seal up some pre-drilled holes in the trunk pan. I have attached an install video for you as well on the above process. We do indeed ship to Canada so...

  • Recommendation for Adding Battery to Toolbox on Travel Trailer Tongue
    Depending on how you mount the battery inside the tongue mounted tool box like # 3371701680, you may or may not need longer battery cables. Since your battery is already mounted in this location, you most likely just need to drill holes and reconnect the same wires. I recommend using the Loctite RTV 598 High-Performance Silicone Gasket Maker # LT37467 to seal those holes to protect moisture from becoming an issue. If you need to run longer cables, I recommend you not splice in a portion,...

  • Installation of Class I Trailer Hitch 24754 in 2012 Mitsubishi Eclipse
    Yes, the minor drilling needed to install Draw-Tite hitch # 24754 in your 2012 Mitsubishi Eclipse can be done with a 1/2-inch bit rather than the specified 15/32 bit. You can use the slightly larger bit since the hole to be drilled takes the 7/16-inch carriage bolt that is secured by a hex nut. You will want to apply a sealer like # LT37467 to the top of the bolt (from inside the trunk) to prevent entry of exhaust gases as you drive.

  • Can T-One Vehicle Wiring Harness # 118449 be Routed Under a 2008 Toyota highlander
    We do not carry the grommet in question for your 2008 Toyota Highlander, but you may still be able to route the wiring under the vehicle and to the hitch using an existing grommet near the connection point for the wiring harness at the rear of the Highlander. If there is a near by grommet that allows access to the outside of the vehicle, what you can do is to cut a small slit in it, pass the 4-Way through, and pull it over to the hitch. You will want to then seal up the slit using silicone...

  • Routing Power Wire for Powered Taillight Converter Through Firewall
    I can't recommend a specific spot but when our install crew routes a power wire, they'll typically find a grommet that's located in the driver's or passenger footwell (under the carpet) or in the firewall. In the firewall, there will be grommets that are used to route wiring harnesses between the dash and the engine compartment. Locate one of the grommets, and use a sharp knife to poke a hole in the grommet next to the wiring harness passing through the grommet. You'll want to be careful...

  • Spray On Rubber Gaskets for Mounting a Cam-Action Lockable Door Latch on a Snowmobile Trailer
    I have a solution for you but we do not sell gaskets specifically for that purpose. Instead, you will want the Loctite RTV 598 High-Performance Silicone Gasket Maker item # LT37467. This will allow you to seal up any holes you have to drill. The Cam-Action Lockable Door Latch w/ 36" Pipe for Enclosed Trailers item # 305736 you were looking at is made of zinc-plated steel that is corrosion resistant. This will work great on your snowmobile trailer.

  • Availability of Cargo Trailer Strap Hinge with Mounting Hole Spacing of 4-1/4-Inches
    I checked the dimensions of all of the strap hinges we offer; all can be seen on the linked page. One of these, Redline part # 2512, did not have the mounting hole spacing noted on the product page so I pulled one from stock so that I could get that information for you. The hole spacing is noted on the linked photo that I have prepared for you. None of these hinges has the exact spacing you're looking for, I'm afraid. If you do end up using an alternate part and have to drill a new hole...

  • Ball Mount and Sealant Recommendation for a 2010 Volkswagen Jetta Sportwagen
    The distance from the top of the Draw-Tite # 24866 down to the ground will be 11 inches. The recommended ball mount is the Sportframe Drawbar # 3593. This ball mount is recommended to only be used in the rise position. Using any other ball mount or even this ball mount in the drop position will void the warranty of the hitch. Basically any RTV gasket maker/sealant would work, but if you are looking for the best I would go with the Loctite RTV 598 High-Performance Silicone Gasket Maker...

  • 2001 Haulmark Replacement Hasp
    The biggest Hasp we carry is the Replacement Hasp for Polar Cam-Action Latch Kits - 1" Wide - Zinc-Plated Steel # 158-101 which has a 4-1/4" measurement from center to center of the bolt holes. Since the length of the hasp is 5-1/8" the body of it should cover the holes so no one can see them. I recommend filling the old holes with some silicone caulk # LT37467 and also putting some in the new holes to prevent water damage.

  • Washer/Sealant for Baggage Door Lock Cylinders
    The washer is not available but since you won't be taking this on and off, you can use some Loctite # LT37467 black gasket maker silicone to seal around that lock.

This is a U-bolt kit that will replace any existing hardware you've got and will use the existing mounting holes, or you can drill new mounting holes to match your crossbar spread.
