HM, Your Professional CNC Aluminum Bungs Manufacturer

If you are looking for a professional supplier of high-quality aluminum bungs, HM can be your first choice. We offer a variety of aluminum bungs, including weld bungs, tank bungs, radiator bungs, gas cap bungs, and injector bungs.

If you need to customize your aluminum bungs to specific sizes, we can accommodate any dimensions based on your business requirements. Common sizes range from small bungs with 1/8″ or 1/4″ NPT threads to larger bungs with 1/2″ or 3/4″ NPT threads. We also provide color customization services, such as blue, black, red, or silver.

Our aluminum bungs are commonly made from 6061-T6 aluminum, a lightweight and corrosion-resistant material widely used in manufacturing and fabrication processes. When you need to deliver liquid or gas, it can create a leak-proof seal. Every HM aluminum bung is very durable, even in extreme conditions, and is easy to assemble.
