Frequently Asked Questions
How does a compression fitting seal?
As you tighten the nut, it presses a brass or plastic ferrule onto the tubing, compressing it against the fitting body to form a watertight seal. No heat or solder is needed.
Do I need thread sealant on compression fittings?
The compression seal itself needs no tape, but the threaded end going into another fitting should get PTFE tape or sealant. Do not over-tighten, which can crush the ferrule.
