SP21 2Pin-12Pin Panel Mount Waterproof Connector IP67,Aviation Plug and Socket,Industrial Electrial Power Connector (3Pin)

Looks like pretty good quality but shipping was slow

I used the male and female version to add a battery bank to my paxcess portable solar generator.

A solid connector , for a good price. It uses a fine tread , makes it a little difficult to get the nuts or cap on. Would not like to do that outdoors in a freezing cold. The lanyard is a little clumsy. But for this price, I'm OK with it.Will use more of this brand.

I suppose for many, the use of a spanner wrench to disconnect the plug from the base is obvious. But if you don't have a collection of spanner wrenches you can use a small screwdriver - as shown in the photo attached. The product itself is perfect for my needs.

Does the trick, exactly what I was looking for to finish my project and works perfectly.

Easy to Insall

Threading cap or mounting screw back on next to impossible without cross-threading due to too fine thread and soft plastic body. The exit hole for the 2 wires is huge and impossible to secure and waterproof the wires on the plug end. No obvious way (or instructions) to remove pins to solder wires without melting the body of the plug and Jack. Length of panel mounted side too short to go through anything but the thinnest material.

These are a good connector for water tight connections.
