NPT Weld Bung – Steel
Finish Line Factory’s precision made, high quality NPT Weld-on Bungs are ideal for the delivery of fuel, oil, water, air, or any fluid of your choice.
Our fittings provide strength in extreme conditions and are easy and fast to assemble. We only use high-quality seals and o-rings to provide a leak-free seal, especially when used with volatile liquids like racing fuels and some oils/coolants. Additionally, each of our fittings is given either a matte or polished finish to provide your vehicle’s fluid delivery system a quality look, feel, and performance.
