Brass fitting makes connecting and disconnecting your BrakeMaster air hose fast and easy.


The connector for my Air Force one supplemental breaking system had come off and drug on the ground ruining it. I had no luck finding one locally but etrailer had just what I needed. Fast service and it was just what I needed.



Still working a year later. Very happy.


Perfect fit, customer service outstandi ng


Great service thanks


After having searched extensively for air quick couplings for our motorhome and toad and having gone to more than a very fair number of possible suppliers, I happened to stumble on THAT was my lucky day! Price and service, I consider them the best in the country.
Give them a try and you'll be glad you did... I can vouch for that.
I got both the male & female couplings so I am good to go for awhile.
May your journey be a memorable one.
That shouldn't be a problem should one ever needs something can supply and deliver in almost the blink of an eye.


Hard to get replacement part arrived promptly & works as it should. Was easy to find on web site. The only down side was the shipping which cost more than double the product because I needed expedited shipping. Overnight would’ve been even more.



Working perfectly since Im more careful to ensure its connected properly!


I failed to verify that the pneumatic line to my dinghy was fully engaged, and when we arrived at our destination, I found that the line had come loose and had dragged during part of the trip. This fitting is an OEM replacement that completely repairs the damage.


My order of a air linel cord for the RoadMaster 9000 was delivered accurately and in a timely manner. All personnel were very helpful and very friendly. I will gladly do business with this company again!


I have often dealt with this company and their service has always been excellent. I highly recommend them.


Fit perfect on my air line for Air force 1 brake system.


Damaged when connecting air line disconnected from back of motorhome. Etrailer was the only place I could find it and was cheaper than paying shipping from manfacture


I ordered the connector from etrailer and received it very quick. Install on our toad was super easy and I’ve towed over 5,000 miles this past year without a single problem. Thanks etrailer for another fine product.


part was exactly what I needed. Air hose for my RV is repaired and installed. Dealer wanted several weeks to order a new hose when all I needed was this fitting.


It was a perfect match. I needed a replacement after the original got damaged. I could not find it at any of the local dealers. I was fortunate to find it on line.


This air coupler worked perfectly to hook up my brakes on the motorhome.


Hard to find air brake connector, as always can get anything we need at etrailer.


I bought this item to carry as a spare in case I damaged an air line. It's just like my original. It's nice to have piece of mind.


Excellent service supplying a hard to find item in a timely and affordable way.
I highly recommend


Had a hard time finding my part, etrailer had it though, so I ordered it, super fast shipping, right part, Thanks etrailer


Good quality fittings for your airlines!


The part I needed for my RV. I will shop etrailer again thanks


Just what I needed. Now I keep a spare connector with me on all trips.


I searched my city for this to no avail, thanks etrailer for stocking what I need!


Air fitting arrived fast and correct.


Ordered item on line got a confirmation right away. Shipped that day and rec’d item as advertised. Would recommend them for your purchases.




works great. you can expect many years of use out of this connector.
