Washdown Turn-Lock Connectors and Cords
When mated, connectors meet NEMA 6P for protection 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 female sockets with an attached cover.
Male receptacles mate with female sockets without an attached cover.
