Inspect the O-rings for debris and for any damage. If there is any question
about the condition of an O-ring, we recommend it be replaced rather than
risk damage to the receiver and therefore your data. O-rings can be
purchased for VEMCO or locally. The replacement O-rings must be
PARKER #2-143 O-RING, 70 Bn NITRILE.
STEP 3
CAUTION:
O-rings can stretch with
continued handling. We advise that
undamaged O-rings not be used for
more than three deployments.
Always wear protective gloves when handling O-
ring grease!
Use your gloved fingers to evenly
spread O-ring grease (we suggest Molykote 55)
over the entire surface of the O-ring until the O-
ring is slippery but doesn’t have clumps of grease
on it. Too much grease can cause an O-ring to
“pop” out of the groove while the case is being
closed, giving little protection from water entering
the VR2Tx.
STEP 4
While you have grease on your glove, spread a very thin layer of the grease
– enough to make the area appear shinny – around the O-ring surface on
the inside of the Outer Cylinder (the smooth area between the threads and
the end of the case). You shouldn’t be able to see grease globs or streaks.
This thin layer of grease will make screwing the two pieces together again
much easier and will also help to create a better seal.
