Video Transcript for Review of JR Products Propane - Adapter Fittings - 37207-30225

Michael: Hi, there. I'm Michael with Today we're going to take a quick look at a propane adapter fitting. If you are needing to connect two different kinds of propane hoses, this is the sort of thing that you would need. This one specifically is going to connect a 3/8" male flare fitting to a 1/4" male fitting. This is the 3/8" NPT female flare fitting, and then this is the female 1/4" NPT fitting.Mostly likely, you've got a trunk hose or an extension hose that you're trying to run from your propane tank to your regulator on your RV or travel trailer.

You've got those hoses, but you need to connect them. This is going to be the piece that you need. Depending on what kind of application, what fittings you have, you do want to make sure to check the fittings on your hoses to make sure that they are going to work with this adapter.If not, we do have other adapters available here at We also have a lot of different hoses with different fittings. It might just be easier for you, instead of trying to hook those two hoses together, just get a longer hose.

Depending on your set-up, obviously it's your call. But we do want to make sure that you're getting the product you need that solves your problem, so you can get back to enjoying your time outdoors.Go ahead and take a look at our other options if you're shopping around. If you already know this is the part that you need, it is a brass construction. It's going to hold up well. You're not going to have to worry about rust or corrosion.

It should make those connections nice and tight, so that you can power up all those propane-powered appliances. That's going to complete our look at the propane adapter fitting. Thanks for watching.

Fitting lets you connect hoses in your RV's propane piping. 2-Way connector ensures gas flows at full capacity.


Perfect fit to go between my propane grill and the quick disconnect hose that goes to my camper's low pressure propane system.


Just the part I needed to complete my propane connection to quick connect. Order was filled and delivered promptly.


I was only able to find this fitting through you. Easy to find and perfect Always a pleasure doing business with you!


I ordered this gas part for my husband. Ordering was easy and payment via PayPal also easy. Delivery was slightly delayed but that was the fault of the carrier not the supplier.


Looked all over Houston - big box, hardware & plumbing stores and could not find one.
I wanted to convert my fire ring hose connection to a quick disconnect.
The connection on the fire ring is a 3/8” male flare.
The quick disconnect fitting is a 1/4” male NPT.
This fitting was exactly what I needed.

This is my second order from trailer and the first order last year was exactly the part I needed.


Works perfectly for my propane grill.


Part fits and performs as expected. Propane service to rv bus.


I bought this fitting to install a quick connect fitting on my grill. The fitting seems correct in terms of size and thread. It attaches to my grill fine. However, the quick connect fitting doesn't screw all the way in. I don't know which of the two pieces is a bit off, but this is why I gave it four stars instead of five. I assume with some teflon tape and a wrench I'll be able to connect it OK, but don't know yet. Otherwise service from etrailer was great and I received the product quickly, even though it was during the holidays.


Perfect fit. It is a hard-to-find item not available in local stores.


I purchased this extension to use with my onboard propane tank to fuel a fire pit. We set up safely well away from the coach. Very pleased.


Was the exactly what I needed and was sent in a timely manner!!


Exactly what I needed delivered on time


Product is great, as described. Service from etrailer is the best around!


I went to two Ace Hardware stores and Home Depot in a vain attempt to find some combination of fittings to convert my Outland propane fire pit to low pressure propane quick connect for use with my travel trailer. Removing the hose & regulator supplied with the fire pit leaves a 3/8" male flare connection. The quick connect fitting has 1/4" Male NPT connection. Voila! This part is all that is needed to bridge the gap. Save yourself a trip and get one if you are making the same conversion.


Worked great and a good price! etrailer was the only place I could locate this adapter


Hard to find fitting but etrailer pulled thru again.


This is exactly what you've been looking for! We have a 24" Outland Firebowl propane fire pit and a 28" Blackstone griddle. Take the regulator hose assembly off and this little gem screws right on there. On the other end use some thread sealer and attach your quick connect propane fitting. Check for leaks and that's it, you're done.


Wired perfectly, thanks


Product was what I needed to connect my grill to trailer.


Perfect for the black stone cooktop we bought!! Made hookups much easier.


This is my 3rd time ordering from They are accurate and ship very quickly. You can't go wrong going through them for your needs. :)


Works perfect great shipping


Exactly the item I needed, hard to find. Thanks for having it, the quick shipment and sending out tracking info right away


Great communication and support and fast delivery.


Works great!

  • Is the JR Products 3/8 Inch Female SAE x 1/4 Inch Female NPT Fitting Left or Right Hand Thread
    The Propane Adapter Fitting - 3/8" Female SAE Flare x 1/4" Female NPT #37207-30225, like most propane fittings, is a standard right hand thread fitting. These fittings are typically used on propane regulators to adapt a pigtail hose with a smaller fitting. The only standard propane fittings that are left hand thread are POL fittings, like part # 204128-MBS.

  • How To Connect A Suburban Elite Griddle To A Disposable 16oz Propane Cylinder
    From what I can see there are a few different models with different connections, with the 3/8" male inverted flare (MIF) being the most common. If this is the case for you then you'll need the following parts: The Propane Adapter Fitting # 37207-30225 will connect to the 3/8" fitting on your griddle. From there you'll connect the 1/4" male NPT fitting of the Quick Disconnect Propane Hose # 37207-31195 to it. The female 1/4" NPT of the quick disconnect on the other end of the hose will...

  • How Do I Connect Griddle To Propane Tank
    If you have a 3/8" male flare fitting on the backside of your regulator that is attached to your griddle, you will need a 3/8" female fitting to make connection and the opposite end of hose will need to have the female POL Type 1 fitting. I suggest the MB Sturgis Propane Hose w/ Back Check - Type 1 x 1/4" MPT - 30", # 100473-30-MBS and then use the Propane Adapter Fitting - 3/8" Female SAE Flare x 1/4" Female NPT, # 37207-30225.

  • Adding A Quick Disconnect Propane Line To Your Grill
    For your Char Broil 4 Burner Propane Grill I recommend attaching part # 37207-30225 to the line coming off of your grill and then attaching part # 401132-MBS to that. Then you'll need a quick disconnect hose which will be part # 37207-31225 for a 6' hose and part # Item # 37207-31235 for a 12' hose I recommend using some thread sealant tape part # 37207-30025 to ensure your connections stay tight and to prevent any leaks. I've attached some videos to offer additional information for you.
