Bulkhead Set-up
Step 1
Drill holes in bulkhead or panel to
accommodate 5502 coupling half and
ange mounting screws. Remove dust
cap before positioning on bulkhead.
Mount male coupling in half by sliding
flange over end of coupling (before
brazing tubing) and attaching to bulkhead
with self tapping sheet metal screws.
Reinstall dust cap before brazing.
Step 2
Braze tubing ends using running water
bath, chill blocks or wet rags on coupling
bodies to prevent seal damage.
Step 3
Remove dust caps and plugs if used,
making sure that component synthetic
seals are intact.
Step 4
Wipe off coupling seals and threaded
surfaces with a clean cloth to prevent the
inclusion of dirt or any foreign material
in the system.
Step 5
LUBRICATE rubber seal in male half
with refrigeration oil. Thread coupling
halves together by hand to insure proper
mating of threads. Use proper size
wrenched (on coupling body hex and
on union nut) and tighten until coupling
bodies “bottom” or a denite resistance
is felt. Using a marker or ink pen, mark a
line lengthwise from the union nut to the
bulkhead. Then tighten an additional 1/8
to 1/4 turn. The misalignment of the line
will show the degree of tightening. This
nal turn is necessary to insure that the
knife edge metal seal bites into the brass
seat of the coupling halves, forming the
leakproof joint. If torque wrench is used,
use the torque values listed in the 5500
series torque specications.
