O-Rings
The Petrel-X has permanent O-rings installed in the head that are not meant to be replaced. The
head of the Petrel-X proper is torqued at the factory to prevent accidental opening.
The O-ring of the battery pack endcap is user-replaceable and should be visually inspected to
make sure it is properly seated in its groove. It should also be inspected for visible damage or
debris.
If the O-rings pass visual inspection and have been deployed for two months or less, they do not
need to be replaced.
If the O-rings fail visual inspection or have been deployed for longer than 2 months, they should
be replaced prior to re-deploying the Petrel-X.
All Petrel-Xs employ O-ring size
2-031/N70
in their endcaps.
Replacing O-Rings
To replace the O-Ring:
●
Remove the old O-ring, and clean all dirt away from the threads and grooves where it was
seated using a lint-free cloth, cleaning alcohol, and a soft-brush.
●
Apply a thin layer of seal lubricant (
MOLYKOTE 111
from Dow Corning) to the new O-ring.
●
Slide the new O-ring down over the threads of the endcap and into the O-ring groove.
It is very important to be aware of where the O-ring is sitting on the end-cap. If the O-ring is not
sitting perfectly in its groove, there will not be a perfect seal; this could cause fatal damage to
the unit.
Connector Grease (Remote Head)
The connector for every Petrel-X Remote Head and battery pack manufactured at Xeos is filled
with grease to protect the conductive material. If replenishing this grease, Xeos recommends
MOLYKOTE 44 Medium
