3 Installing the Air Locker
15
Install the spring clip by first hooking both ends of the clip into the
small aligned cutouts of the seal housing and the adjuster nut, and
then snapping the clip into the groove of the seal housing using a
screwdriver. (Fig.9.)
Figure 9.
Check that the seal housing is now secured from rotating and that it
is still sitting flat against the adjuster nut.
3.7 Setting up the Bulkhead Fitting
Apply thread sealant to the threads of the bulkhead body.
Screw the bulkhead body into the tapped hole, and tighten.
Wipe the area clean of any excess thread sealant (inside and
outside of the housing).
Without using sharp, jagged tools such as pliers (your hands are
the best tool for this job), bend the seal housing tube on the outside
of the housing to approximate the finished profile. This will allow the
tube to be trimmed to a length that would allow it to protrude from
the bulkhead fitting. (Figs.11.,12. & 13.)
IMPORTANT:
The seal housing must still be able to freely float after the tube
is connected to the bulkhead fitting. Therefore, it is critical to
ensure that the tube is not under any tension. To avoid this
always leave the tube long enough so that a hook shape can be
formed between the seal housing and the bulkhead.
