IP67 4-Pin Aviation Connector – 30A, Welding-Free, Screw Terminal, Industrial Plug Socket Set

Working on an industrial or automotive project that needs a tough, waterproof connection?

These 4-pin aviation-style connectors are exactly what you need.

The best part?

No welding required—both ends use screw terminals, so you just strip your wire, screw it down, and you're connected.

It's a male + female set, rated at 30A and IP67 waterproof, so it's fine for outdoor or wet environments.

The socket mounts to a panel, and the plug connects securely.

Wire gauge compatibility is wide—from 3/0 AWG down to 2 AWG—so it handles thick cables.

It's got 4 pins, 2 poles, and handles both AC and DC.

MPN is CLSP21-CLS-MHJ-4P.

If you're into custom wiring, battery setups, or industrial machinery, these connectors make life easy.

No soldering, no mess, just solid connections.
