Vibrant M12 x 1.0 Metric Port Plug w/ Crush Washer

This is a Vibrant M12 x 1.0 metric port plug, designed to seal off threaded ports on your vehicle. It's made from 6061 aluminum alloy and comes in a black anodized finish. The plug includes a crush washer, which is crucial for creating a tight seal and preventing leaks when you tighten it down.

You'll use a plug like this when you've removed a sensor, fitting, or other component and need to close off the threaded opening. It's a simple but effective way to keep dirt, debris, and moisture out of sensitive areas like your engine or fuel system, and it stops any fluids from escaping.
