Corrosion Avoidance - Teledyne SeaBat T Series Operator's Manual

SAFETY PRECAUTIONS
A long range of chemicals will destroy the polyurethane, which includes, but are not limited to:
 Acids
 Automotive brake fluid
 Base
 Grease
 Halogenated hydrocarbons (carbon
tetrachloride, trichloroethylene)
 Hydraulic fluids
2.2.2.2 Wet-End Connectors
Use the wet connector lubrication kit (PN 1007252) to protect the wet-end connectors. Follow
these guidelines:
 Lubricate female connectors and dummy plugs with a silicone oil or equivalent
(silicone oil based). Observe the instructions provided with the lubrication kit.
 Lubrication intervals depend on mission type and frequency.
 DO NOT grease mating surface.
 Avoid nicks and cuts around contacts as these are the sealing surfaces.
 Elastomers can be seriously degraded if exposed to direct sunlight or high ozone
levels for extended periods of time.
 Do not overtighten bulkhead nuts.
 Grip main body of connector during mating or unmating. Do not pull on cable to
disconnect.
 Avoid sharp bends at cable entry to connector.
2.3

Corrosion Avoidance

It is important that your SeaBat™ system be properly protected from the corrosive effects of the
water in which the sonar head and SSP are submerged.
Take the following precautions to ensure the best usage of your SeaBat system.
 Maintain electrical isolation between the sonar head and the mounting structure.
 Ensure that the SSP is isolated from the vehicle metal frame to protect the
polyurethane- and rubber-molded connectors.
SeaBat T-Series Subsea Operator's Manual
Version 7
o Lubricate every 5 matings.
o Lubricate at regular intervals, even if the connectors are not mated/unmated,
in particular for UUVs where the dive tends to rub and wash out the lubricant.
o Lubricate twice a year when equipment is in storage.
CAUTION
 Ketones (MEK, acetone)
 Nitro hydrocarbons (nitrobenzene, aniline)
 Oil
 Ozone
 Petrol
 Phosphate ester
