Re: sealing leaks

Are the leaks at the threaded joints, or elsewhere?

For pipe thread joints:
5 wraps of PTFE tape and 3/4+ turns after finger tight. Make sure that the first thread is not taped and that there is no tape on the front face of the male fitting. Clean off old tape and re-tape if the fitting is being reused. PTFE tape does not seal well if reused.

If the leaks are out of the "One Touch" style tube fittings--The NUMBER 1 OFFENDER is the tube ends NOT being cut square. If tubes are cut at a slant, or not cut cleanly, the o-ring seals at the bottom of the fittings will not make a good seal all around the tube.
