Question:

# F3025-1....Leaking air Ive tried two different T fittings and keep leaking air at the incoming air line. Ive made sure the 1/4 line has a nice clean and square cut and was pushed all the way into the fitting but it still leaks air. Any suggestions? Thanks!

For your Air Spring Union Tee like # F3025-1 the only troubleshooting you can do is what you have already been doing. The Tee fittings simply use a compression so pushing into place is all that is required. The clean 90 degree cut is also all that is needed on the tubing. Then you use soapy water to check for leaks.

The one thing that can be an issue is if the hosing is overly compressed when cutting like using a scissors for example. That is why the manufacturers make the tubing cutter # AL10530.

Since you've already replaced the tee fitting, I recommend trying the cutter or replacing the tubing with Firestone 1/4" Air Line Tubing - 22' Long, Red # F99ZR.
