I use the poly glad hand seals. Red and blue. Last MUCH longer than the rubber ones.

Used to have to replace the rubber ones every 4-6mths. The poly ones usually a couple of years.
I am guessing a bit cheeper than the quick disconnects.

Absolutely! Poly hold up very well. Need to get the correct style though. One is better than the other.

This is the style you want with the narrow lip-



The usual wide lip seals tear that lip off and damage the rest of the face quicker.

The Iowa80 truckstop www.iowa80.com is in my backyard, of sorts. ;) But, most any big truck parts store should have them.

Don't have the answer but I have see a lot of show quality trucks with quick connects, maybe call a custom shop ,

The glad hand is an out of date contraption and are a real pain hose to hose
quick couplers would make your trailer harder to steal also.
There must be DOT couplers out there some where,Vaccuum over hydraulic uses quick couplers, they must be DOT??
Glad hands separate from other if you forget to unhook them, that's why they are how they are. Do that with quick connects and you'll be replacing them if you ever forget. If you ever do.

way less air flow through a quick coupler than a glad hand.

Try this. build air till compressor shuts off then shut the truck off, push red button in with no trailer and time till button pops out. install quick coupler and put the male end into that you are going to use. Then build air and time how long it takes to bleed down, it will be longer.

Another is freezing through the coupler even in above freezing temperature. Any gas flowing from a high pressure to a low pressure will freeze at the choke point. Think about when you drain your shop compressor in the middle of summer the drain will freeze. It is possible that when charging a trailer freezing could occur at the quick coupler because of the restriction.
