Vibrant M16 x 1.5 Metric Aluminum Port Plug with Crush Washer

This is a Vibrant M16 x 1.5 metric port plug, made from 6061 aluminum alloy and finished in black anodize. It comes with a crush washer, making it ready to seal off exposed ports on your engine or fabrication project. These plugs are a straightforward way to prevent leaks and stop dirt, debris, or other contaminants from getting into open ports.

Using a plug like this is common when you're modifying an engine, rerouting lines, or cleaning up a custom build. The aluminum construction is lightweight, and the included crush washer helps create a solid seal against the mating surface. It's a simple part, but it plays an important role in keeping your engine bay clean and your fluid systems secure.
