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.

Abrasion-Resistant Turn-Lock Extension Cords

NEMA L15-20 Plug

NEMA L15-20 Socket

Thick insulation protects the internal wires of these cords, so they can be used in high-traffic areas and over rough areas. The insulation also resists water. Give the connectors a quarter turn to lock in place; they remain secure in high-vibration applications.
