2. 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 (part #10-568) to all three inside surfaces of the groove, being
careful not to trap any dirt, hairs or lint.
3. Select the proper O-ring and make sure it is not damaged. Lubricate it with a very light
film of silicone grease to ease its installation. The correct order and orientation is as
follows (assuming the o-rings have been removed): Install the main o-ring first by sliding
it over the electronics housing (it is too small to fit over the sensor cap). Install the back
up o-ring making sure that the concave part faces toward the sensor end and will mate
with the main o-ring. The flat part of the backup o-ring must mate flat with the o-ring
backing wall. Make sure there are no twists in either o-ring.
4. 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.
Many 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. Routine replacement of O-rings, therefore, is cheap
insurance.
