Russell Performance 1/8in Female NPT Weld Bungs (1/8in -27 NPT)

If you're fabricating a custom exhaust system or need to add a port for a sensor to a fuel tank, a weld bung is a handy part to have. This weld bung from Russell Performance gives you a clean 1/8 inch female NPT threaded port that you can weld onto steel or aluminum tubing. It's made from 6061-T6 aluminum, which is lightweight and easy to weld, and features a welding lip that helps prevent the threads from warping during the welding process.

This bung is designed to accept standard 1/8 inch - 27 NPT fittings, which are common for things like pressure sensors or drain plugs. Being made of aluminum, it's a good choice for custom fuel tanks or oil pans where weight savings might be a consideration. It's also made in the USA.
