Weld-On NPT Female Port for Aluminium Fabrication

These aluminium weld-on adapters provide a female NPT connection on fabricated aluminium tanks, pipes and other compatible components. The raw aluminium weld base is designed for permanent welding, with the internal tapered NPT thread providing the fluid connection.

Female NPT Connection

The female NPT connection uses a tapered thread for connection to a compatible male NPT fitting. Use suitable PTFE tape or thread sealant.

Designed for Aluminium Fabrication

The weld base is supplied with a raw, uncoated aluminium finish suitable for welding into compatible aluminium components.
