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The glad hand is an out of date contraption and are a real pain hose to hose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??

A lowboy (RGN) uses quick couplers between the neck and the deck...I don't see how your situation would be any different really. I'll agree with the gladhands are out of date comment too...the quick connects last much longer and with some WD40 once in a while are much easier...no rubbers to wear out.

Just make sure you paint 'em red and blue so as not to confuse them.

Save your paint... one airline female connector on tractor end and other line male connector on tractor. Cannot be hooked up wrong...
As was said earlier, works great on lowbed gooseneck...;)

i've been running them for about 3 years. never had a comment. cool thing about them is when you are hooking up a trailer. air is already available at the hose. when you connect , your bags will start filling, making it easier to crank up the legs.saves a trip back into the cab for me.

I suggest using connectors that are totally brass or stainless. Tried using galvanized (which are the most common) and they were junk within a year. So rusty you couldn't hardly move them. Of course this is in Ohio and salt kills everything.

J... Same here in Massachusetts, the crap they use on roads in winter (salt, calcium chloride and whatever else) is brutal on vehicles...:gaah

All we use out here in Australia are quick couplers.

They work great, and when you hook up, trailer starts charging right away to fill the bags and tank.

We use this style on all our equipment.



We stopped using glad hands maybe 20-30 years ago.

We use Duo-matics on our dump trucks.

I looked in my inspection manual, and it says glad hands, but I do not see a problem, using a set of air line couplers, one quarter inch, Seem a little small but three eight`s would be plenty. You would want to have a set of adapters, just in case you had to use or move someone else's trailer. You also would need to have a set on you trailer just in case someone had to move your unit. I would ask the next time you get stopped and inspected by the MOT.

the only downfall i see to quick couplers is in winter weather. I can see them full of road salt, sand etc and ffrrrroooozzzzeeeenn. Go through it all winter with low bed detach connections...
As we dont have snow at all, salt may be an issue, We use them in all conditions, and we have red dust issues, but a good tap knocks all the dirt out before you couple.

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.
