Step 1 Clean up the two threaded joints that need to be sealed and keep them clean.
Step 2 Wrap the end of the teflon tape around the inner threaded interface, usually 4-5 turns, and then cut the tape. Step 3 Thread the male connector onto the tape-wrapped female connector and tighten, then test the performance
Tips: The winding direction should be consistent with the rotation direction of the two interfaces.
