455 Balanced Regulator Installation
Exhaust System Installation
1.2.3 Exhaust System Installation
NOTE
Every effort is made to ensure that this,
and any of Kirby Morgan’s regulators, are
interchangeable among the wide variety
of helmets and masks that Kirby Morgan
produces. 40 plus years of producing
thousands of helmets has resulted in
some variations. Please be aware that the
final alignment of the regulator may have
variation from unit to unit, and this in no way
will affect the function and/or performance
of the finished 455 regulator.
EXHAUST SYSTEM NOTE:
Each Quad and Tri-
Valve exhaust assembly can be removed and
replaced onto the exhaust flange of the regulator
as a complete unit. If assembled using the indi-
vidual components, special attention is required
to ensure the exhaust valves are correctly orien-
tated and seated inside the exhaust whiskers. If
replacing valves or rebuilding the exhaust valve
assembly by individual components see Quad
Valve and Tri-Valve section in our modular manual
1. Insert the opening on the exhaust main body
onto the exhaust outlet of the water dump valve,
while at the same time aligning and inserting the
threaded mounting tube on the regulator, into the
mounting hole on the pod.
2. Install the tie wrap around the quad main
exhaust body and tighten. Cut and remove excess
tie wrap.
This tie wrap can also be preinstalled
prior to step one.
3. Inspect the regulator mount nut for
contaminants and damage. Use a tooth brush
to clean threads as needed. Lightly lubricate the
regulator mounting tube threads and the sealing
O-ring with Christo-Lube
®
.
4. Install the sealing O-ring, then thread the
regulator mount nut onto the regulator, finger
tight ONLY.
