Duraline’s Industrial / Commercial Grade Quick disconnect Multi-Pin Connectors are constructed using the highest quality materials to insure long life and trouble-free operation. Each connector is thoroughly inspected and repeatedly tested during the manufacturing process. All Duraline connectors are molded in rubber permanently bonded to heavy duty cable. The connector’s unique seal designs isolates one contact from each other and creates a watertight seal allowing the mated pairs to be immersed in up to 6′ of water.
