4.9 Setting Up the Bulkhead Fitting
NOTE : Use an automotive brake line tubing cutter to cut the
seal housing tube. Never use a hacksaw for trimming
the steel tube as this will leave metal fillings in the air
system.
 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).
 Insert the free end of the seal housing tube into the bulkhead fitting
until it protrudes approximately 8mm [5/16”] through the other side.
 From the outside of the housing, assemble the small O-ring over
the top of the short length of seal housing tube protruding through
the bulkhead fitting.
 While holding the seal housing tube into the bulkhead fitting, insert
the small drilled end of the center compression nut over the
extended tube as shown in the assembly diagram (Fig.13.), and
screw it into the bulkhead body, and lightly tighten.
