HMParts Superseal 5 Pin Car Plug Connector Kit - 0.75-1.50mm² Waterproof Coupler Set

Need to fix a wiring harness or build a new one from scratch?

These HMParts Superseal connectors are the way to go.

This set gives you a 5-pin car plug coupler that’s waterproof, so it’s perfect for engine bays, exterior lighting, or any spot that gets wet.

It accepts wire sizes from 0.75 to 1.50 mm², which covers a lot of standard automotive wiring.

The brand is listed under a few names—HMParts and Einzel- und Großhandel Schneider Franz Xaver—but it’s the same high-quality KFZ-Kabelverbinder (that’s German for automotive connector).

It’s manufactured in China.

The EAN is 4250458128306.

These are great for repairs or custom projects where you need a reliable, weather-tight connection.

They click together securely and seal out moisture, dirt, and corrosion.

If you're rewiring a trailer or repairing a sensor plug, this is a pro-level fix.
