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


great and quick service. second time i have used your products, they always as ordered. thanks for the prompt attention to my needs.


Exactly the part that I needed thanks. Whenever I need parts of my RV I would definitely go through etrailer.


Found while making a search for a part that could not be located in New Mexico, Arizona, Utah and Colorado. The part was originally back ordered. Lori B got involved and found the part under a different manufacturer. It shipped immediately and arrived on time. Then, which seldom ever happens, Lori B followed up to indicated the part had been delivered to the address. Confirmed it is there. I am very impressed with Lori B and her customer service skills. Refreshing!!!!!


would like to see better identification of what your items fit. I used standard delivery options, that took about a week longer longer than anticipated. If my unit was in a repair center, that would have been a issue for what was needed. Personal very helpful.


Product was what I needed, price was not a choice, pay it if you want it! Took quite a while to get it, but it arrived as advertised!


Perfect just what I needed .


Arrived quickly


Quality items for sure! Not inexpensive, but they're currently doing their job, of which I bought them for!


Helped me finish up on my Brakemaster install between our motor home and Jeep - everything works great!


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.


On a recent trip I broke an air line connector in my towing brake system. Four RV stores in 3 states didn't have the part, but then I found it on etrailer. Ordering was easy and the correct part arrived quickly. Very happy with both their product selection and their service.


Product good! USPS shipping bad!!!


The website and ordering process made this so easy to select the correct parts. The tracking process after ordering was a great help since it was sent to a campground. We received the product in the timeframe we selected for shipping. We would order again and would recommend it to everyone.


Adapted to standard air hose connector for checking operation of BrakeMaster and Brake-Away on "tow'd" without having to connect to motorhome.


Product was delivered in a timely manner. This connection was for the air line that went from my motorhome to the breaking system on my car. Had looked locally for connection for over a month. Very pleased!


This part was a hard to find piece. You had what I needed and it was sent to me in a reasonable time.
This part helped me purge my inline air tank for the air braking system on my car.
Thanks for your help.


Purchased these to replace existing connectors, old ones would come disconnect on the road. New ones road tested perfect. Etrailer are the only ones that sell these separate and don't cost an arm and a leg. Delivery was prompt.


They fit and function just right


Exact replacement that was needed to repair my Roadmaster air system. It was shipped and received in a timely manner.


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


Item as described


Had the part I needed. Booked marked and will be purchase here again.


Great service, fast shipping


A hard to find replacement part in local brick & mortar stores. After ordering I was notified item was back-ordered but only waited a few days for shipment. Very happy with communications and service.


you guys have always provided the best customer service, that's why I only buy from you guys when you have the product I'm looking for. Thanks for the follow up........ I have never had ANY company do that before, and that says a lot because I have been buying stuff for 60 years.

After a year and 3 trips coast to coast your product still works like a charm, never had a single problem with it. Thanks for the follow up.
