Circular Connector Seals

Circular connector seals are a component of circular connectors that form the environmental seal within the connector interface. Such seals are formed of a resilient, typically compressible material such as rubber or plastic and are mounted either within the connector between the mating surfaces, or between the connector and the cable as cable entry shields to prevent contaminants migrating along the cable towards the connector.

What are circular connector seals used for?

Circular connector seals are designed to withstand exposure to extreme temperatures, moisture and harsh engine compartment fluids and chemicals. Connector seals are necessary for a wide range of applications, in particular those that require sealed plugs, receptacles and power connectors.

Applications of circular connector seals
