	home	about us	Crouse-Hinds	employment

Features

• Exclusive construction of these patented WATERMATE electrical connectors permits underwater plugging and unplugging with electrical power de-energized.

• Pressure rated up to 20,000 psi or maximum 45,000 feet of sea water (except Series 53 which is rated up to 10,000 psi).

• Pressure balanced for easy engagement and disengagement in high pressure environments.

• 53 and B53 Series permit leak-proof hull penetration.

• Rubber-to-rubber contact of specially formulated neoprene provides total sealing integrity when properly installed and maintained.

• Locking sleeves are available for positive plug retention.

• B51 and B53 Series have a flanged body to retain locking sleeves.

ELECTRO SERIES 51 MALE

Applications

Some typical uses of underwater pluggable WATERMATE Plugs, Receptacles and Connectors are in power and/or control circuits for: • Underwater instrumentation and control packages

• Underwater cameras

• Sonar equipment

• Underwater electrical power distribution systems

• Underwater fighting systems

These underwater applications are frequently found in:

• Diving bells

• Submarines

• Ships

• Diving helmets

• Submersible pumps

For offshore marine installation of moorings, dock facilities, petroleum production platforms, etc.

Important Note:

Bulkhead connectors must be installed with pigtails on low pressure side of bulkheads or interior of vessels. Pressure on pigtail side must not exceed the pressure on external side of connector.

Installation, Maintenance, And Lubrication Instructions

These instructions are applicable for Series 51, 53, B51, B53, 59, 510, 52, 610 and 41 products.

Lubrication

To optimize the performance of these products, pins and sockets of mating connectors must be lubricated with silicone grease, (e.g. Dow Corning #4 or General Electric lnsulgreasee #635). Grease should be applied to the entire surface of each malecontact pin. A small amount of silicone grease should be placed inside the entry hole of the female socket. Products must be relubricated on a regular maintenance cycle.

Mating And Unmating

Connector must be well lubricated. Insertion should be accomplished with as little flexing as possible. Separation of multi-conductor connectors can be aided by flexing the connector head up to 150 to help the separation process. Flexing beyond 150 must be avoided.

Mounting Of Bulkhead Penetrators

For 59 and 510 Series - Drill holes with sufficient clearance for diameter of threaded body. Coat the rubber skirt on the bottom of connector with silicone grease to insure a good seal. Install washer and jam nut from low pressure side with sufficient pressure to keep connector from turning. Extreme bending of connector during mating may temporarily affect the seal. For 53 and 41 Series - Drill and tap hole to match thread size of connector. Lubricate the 0-ring with silicone grease to improve seal. Torque down hand-tight and, then add 1/4 turn more with a wrench. Bulkhead connectors must be installed with pigtails on low pressure side of bulkheads or interior of vessels. Pressure on pigtail side must not exceed the pressure on external side of connector.

Handling

Extreme flexing and rough handling will reduce the useful life of these connectors.

Dummy Connectors

Unmated connectors should not be exposed to water for an extended period. Dummy connectors should be used to purge water from the contact surfaces to reduce corrosion. Dummy female connectors will help to protect exposed pin contacts from possible physical damage.
