O-Ring Considerations
The 8242XS End Cap assemblies use a standard O-ring to provide watertight integrity to the Electronics
Housing. Under normal usage, proper care, and lubrication, the O-ring should provide several years of
usage. However, like the batteries, the O-ring is an inexpensive component, which is absolutely critical to
the successful operation of the entire system. Depending on the frequency of use, it is a good practice to
periodically replace the O-ring. It is essential to inspect the O-Rings and sealing surfaces before and after
each deployment.
Prepare the sealing surfaces for assembly by cleaning with a lint-free towel or swab, moistened (if needed)
with alcohol. Inspect for scratches or nicks which could impair the O-ring’s ability to provide a seal. Apply
a light coat of O-ring lubricant (EdgeTech recommends Parker Super O-lube, be sure to use only silicone
grease) to the Housing and O-ring to facilitate insertion of the end cap. Make sure the lubricant is
compatible with Nitrile rubber. Inspect the O-ring for damage such as tears, dimples, or other defects in
the rubber. Replace any O-ring that is questionable or old. Lightly coat the O-ring with lubricant. Protect
O-Rings when stretching them over large diameters.
CAUTION!
Applying too much lubricant to the O-ring can compromise the seal.
CAUTION!
The ends of the housing are O-ring seating surfaces. They must be
protected while the unit is disassembled. Any scratches will impair the
performance of the O-Rings and may result in leaks.
Additional O-Rings
There are additional O-Rings that provide the watertight integrity to the Housing. These are located on
the Purge Port, T-Shaft, and On/Off Actuator Plug or Dummy Plug. Check and replace these O-Rings
periodically.
O-Ring Service Disassembly
If you are servicing O-rings or wish to inspect the Release End:
1.
Follow the disassembly instructions in
2.
Clean, Inspect, and lightly Grease the O-rings as shown in
EdgeTech recommends the use of Parker Super O-lube, be sure to use only silicone grease.
