If the O-ring is scratched, cut, distorted, perished or defective in any other way it must be replaced. If any of the surfaces
of the O-ring groove are scratched, pitted or otherwise damaged, the logger may need to be returned to RBR for
refurbishment: please contact us for advice.
Replacing an O-ring
Lever the O-ring from its groove. Use a soft plastic or wood tool; do not use a metal screwdriver or any
other tool which may scratch the surfaces of the O-ring groove, doing so will probably render the end
cap useless. Slide the O-ring out of its groove and off the logger. The O-ring may need to stretch quite
a bit as it is pushed off; this requires some effort but can be done by hand.
Thoroughly clean the O-ring groove, taking great care not to scratch or damage it in any way. Inspect it
carefully, and contact us for advice if it appears damaged. Apply a light film of silicone grease to all
three inside surfaces of the groove, being careful not to trap any dirt, hairs or lint.
Select the proper O-ring, see part numbers below, and make sure it is not damaged. Lubricate it with a
very light film of silicone grease to ease its installation.
Install the new O-ring by pushing it into place and popping it into its groove.
When the new O-ring is in place, inspect it once more for scratches and dirt, and wipe away any
silicone grease deposited on the end cap.
Most experienced users of oceanographic equipment replace all O-rings before every deployment as a matter of
routine. The cost of an O-ring is negligible compared with the cost of the instrument and its deployment. Therefore,
routine replacement of O-rings is cheap insurance.

The single most important item of maintenance on any RBR submersible data logger is the care of the O-rings. Any kind
of water leak can damage the circuitry beyond repair and cause complete data loss. Every logger's seal depends upon
its O-rings, not the end cap tightness. Therefore, proper O-ring maintenance is crucial.
O-rings may lose elasticity over time due to pressure, even when the logger is not deployed. We strongly
suggest that the O-rings be replaced regularly, for example, before every deployment, or after a change of
batteries, or at least once a year.
