5) Place silicone lubricant on the components
then wipe clean. Be careful to wipe the poppet
(110) and poppet O-ring (109) thoroughly, re-
moving nearly all silicone to prevent foreign
materials from sticking to these components.
6) Inspect the spring (111) and clean or replace if
necessary.
5.5.3.2 Reassembly of the One-way Valve (103)
1) Insert the spring (111) in the valve body (112),
followed by the poppet (110).
2) The O-ring (109) should engage the poppet
(110).
3) Next, install the O-ring (108), wiper (107), on
the seat (106).
4) Tighten the seat (106) with a wrench while
holding the body in a soft jaw vice.
5) If the adapter (105) has been removed, it
should be wrapped with Teflon tape on the ta-
pered pipe threads and reinstalled at this time.
Tighten the adapter.
DANGER: Do not allow any excess
Teflon tape to cover the end of the adapter
(105), or to enter the one-way valve (104).
Loose pieces of Teflon tape can interfere
with the performance of the one-way valve
or the regulator and may block the diver’s
air supply. This could lead to death
through suffocation.
7) Reinstall the valve assembly (114) in the
sideblock (94a/b) and tighten.
