Harsh Environment Straight-Blade Plugs, Sockets, and Receptacles

Rated NEMA 6P, 13, IP66, and IP69K when mated, connectors withstand oil/coolant spraying; temporary submersion; high-pressure, high-temperature washdowns; and are corrosion resistant so they can be used in marine environments.

Plugs have a multiple-ring seal to keep out liquid when mated. They have a locking ring that screws together with sockets and receptacles so connections remain secure in high-vibration applications such as oil drilling and mining operations.

Sockets and receptacles have an attached cover that creates a watertight seal when not in use.

Note: The current rating of your plug should not exceed that of your socket or receptacle.

Washdown Straight-Blade Connectors and Cords

All connectors have a multiple-ring seal and rubber housing to keep out liquid. They resist heat, oil, and chemicals. When mated, connectors meet NEMA 6P, NEMA 12, and either IP67 or IP69K.

Connectors that meet IP69K resist high-pressure washdowns.

Plugs mate with female receptacles and female sockets with an attached cover.

Male receptacles mate with female sockets without an attached cover.

Note: The current rating of your plug should not exceed that of your socket or receptacle.
