Glad Hand Seals

I like the type of gladhand seal shown on the left side of this picture... Way less likely to leak. Especially when trailers changed frequently there is almost no need to double check a red hose connection

 

You know. That's not a dumb question in the least.
From my testing they will work fine either way.
But I've always put the bigger end in the glad hand with the smaller donut part sticking out.
It protrudes out more for better seal.
I guess it could just come down to trial & error on what you like best.

 

SONOFAGUN!

According to him I've been doing it wrong.

 

LOL!
I tried using the neoprene ones and thought they were junk because they kept falling out, now i know i was installing them wrong!

 

WTF? Ive never had a problem with this. They never pop out the right way. He must get some crap cheap seals. I only use the ones with the stainless steel screen, to keep the bugs out when unhooked. The purpose of the larger seal face is to extend the seal surface area. If yours dont seal that way, your glad hands need to be replaced.

 

LOL I know Cetane. I've never had one come out either. And the "wrong" way is a heckuva lot faster I bet. Notice how the video was cut and edited as he was "finessing" it in there. Prolly took a half and hour and some cussing. Good post though. Thanks to the OP!
