Is there tips/tricks how you go about sealing up air leak on quick connectors? I have new cab air bag and it just seeps air. I've tried cutting off end and reinserting but still does it. I've heard heating end of air line before Install works.

Can u replace the quick connect ? Or is the one thats on the bag itself ? I think quick connects are always gonna leak a little bit... Ive had better luck with the brass ones rather then the plastic ones but they all leak eventually... Sometimes if ur cut is not perfectly straight on the air hose it will leak..sometimes the cut and reinsert works, i just got one to stop leaking like that but i know come winter time it will leak again..
How much is it leaking? Can u hear it ? Or u just spraying it with soap and water and making bubbles?Rideandrepair Thanks this. -
I can hear it leaking and it's brass quick connector on the bag itself. Very hard to get to since it's between fuel tank and frame

Well that really sucks. Especially if its a new bag.. You may just have to replace with new bag unfortunstely . i think those quick connects are internal and cant be changed... Me personally i may try to put a wrap of electrical tape or duct tape around the end of the hose and shove it back in there.. That may give you the clearence you need to stop it from leaking

In an emergency, you could try running a bead of superglue in the gap between the hose and the connector. But remove all the pressure from the system first.

You pop the ring off, use a paper lip to remove o ring. Usually the o rings are a bit fatter than average. Might not be in the HF special assortment pack. New o ring put ring back on. Best to get actual compression fittings with a ferule, and an insert. No more leaks. Last forever. Replace ferule only when changing air bag next time. Costs about the same. Any Hardware store. The Parker Store is a good source for them and the quick connects. While there, might want to get extra ferules in each size, and one each size quick connects, then when at Dealership get a foot of each size plastic line. It’s all cheap. Keep for emergency, add a couple brake hose mender couplers. One each size. Never be stranded. Good for a OOS chafed line. Avoid a road call.
D.Tibbitt Thanks this.
