In the front end of my DS 4304 there is an air hose coupler for primarily a tow truck connection to maintain emergency brakes released. Does anyone out there know which type of coupler this is? I believe they are divided into A,B,C,D categories/types. I need to convert my air hose to the same type fitting.

Didn't know that's what that coupler was for. I use mine to air up my tires. There are two types of couplers, A and I/M. Mine on my 2017 is the I/M type.

My connectors look like this----

They have a wide section near the end. They are not one of the most common used but are easy to find.

Can't answer as to which one you have but when you DO determine which one, buy a spare male fitting, put it into a plastic wrap and tie it to the female coupler.
Then if you ever need to be towed, and I hope you don't, the tow truck driver will have the correct fitting to connect to your coach so he can release the air brakes. Trust me, it may save you a lot of frustration.

Mine is industrial vs Automotive.

I have the female on the manifold up front for towing...funny the tow truck has the same.

I've since made a male-male adapter, in case I need to be towed again.
