Found leak – how do you tighten up this connector?
Hi All,
I found the leak in the front of our bus – it’s this red line. I can move the line around and the leak will alter, stop, etc… so it’s this line.
But – how do you “re-do” this connetcion to stop the leak? Here is what is is:
I’ve only really ever used the sort of push in type with the orange ring around it. I’m not familiar with this connection. Any help is appreciated!

Go buy a DOT approved Compression fitting, and replace that Push n Lock fitting you have. To get the line out, push in on the line, at the same time, hold the brass ring down, and pull the line out. A small open end wrench will sometimes help hold pressure against the ring, while you pull the line out.

Walt,
All of us with coaches that have predominantly push in fittings at some point will have to address leaks because as they age the rubber seal tends to dry out and not seal as well.
Compression fittings are reliable, re-useable, and last a long time so as Jerry suggests try to get a compression fitting to replace the leaker. If you have sufficient slack in the red plastic line you can cut it instead of struggling to pull the hose because you need to cut the hose a little anyway so the end going into the compression fitting ferrule is smooth and free of damage.
Make sure your air pressure in the brake system is zero or expect air to escape when you separate the hose and fitting. The first time you separate hoses and fittings under pressure unexpectedly it gives you a rush.
Don’t get under your coach without supporting it, and especially when doing anything on the pneumatic system. The red color indicates that is your secondary brake circuit.

Replace it Walt, those old fittings will usually not re-seal even if you cut off the line for a new bite. As the others have said, DOT compression is best, but I’ve use the black DOT push ins with good success.
