Frequently Asked
Do different colors connect together?
No — SB50 housings are mechanically-keyed (slightly different) to prevent fitting together with the wrong color. Different colors give you the option to have multiple connectors, with different purposes, and avoid accidental cross connection.
Do these fit other brands?
YES — Generally speaking these SB50 housings are designed to fit other brands of the same housing & color. However, it is recommended to purchase matching sets to eliminate the chance of a mis-match.
What does “chosen selection” mean for this kit?
Your kit contents match the variant you choose — including the housing color and the crimp pin size (to suit your cable). Make sure your selection matches your wiring and any existing connectors you’re expanding.
Can I Mix & Match Wire/Pin Sizes?
YES — You can use mixed wire/pin sizes, so long as the housings are matched and you are using pins suited for the housing. This is a great way to downsize wire after a long (upsized) run, and offer easy connections.
Are the crimp pins silver-plated copper?
Yes — the included crimp pins are silver-plated copper for excellent conductivity and improved corrosion resistance in real-world installs.
Can I use these for inverters, chargers, and solar gear?
Definitely. SB-style quick-disconnects are commonly used for battery banks, inverters, chargers, DC-DC chargers, and portable power builds where you want a secure connector that’s easy to disconnect when needed.
Do I need a special tool to install the pins?
A quality crimp tool for your chosen pin size is strongly recommended for the best connection. Hydraulic/Hex crimpers are not required, but are recommended.
After crimping, always tug-test the cable and verify the pin is fully seated in the housing.
It is recommended to perform a load test and check operating temperatures after you have assembled the connections
