Washdown Turn-Lock Connectors

When mated, connectors are protected against corrosion and washdowns. All have a multiple-ring seal and rubber housing to keep out liquid. They resist heat, oil, and chemicals. A quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection.

Plugs mate with female receptacles and sockets with an attached cover. Male receptacles mate with sockets without an attached cover.
