(b) On tubing of 1/16, 1/8, and 3/16 inch diameter, tighten only 3/4 turn.

On tubing with 1/16, 1/8, or 3/16 inch diameter, tighten 3/4 of a turn.

F. Application of Teflon Tape Thread Sealant
All male pipe (tapered) threads of the oxygen system should be sealed with 3M No. 48 teflon tape.
Teflon tape should not be used on straight threads. Do not use any other lubricants in place of the
teflon or on any other threads.
(1) Wrap tape on the threads, starting with those farthest from the opening, in the direction of the
thread spiral. Circle the threads, making sure that each side of the tape has a slight overlap.
(2) Wrap the tape such that it does not extend beyond the last thread on the fitting at the opening.
The tape should then be pulled till it separates. Do not cut tape, it will not stick properly.
