Reducer Coupling for FNPT Piping

This white PTFE reducing coupling connects a two-inch female NPT thread to a one-half-inch female NPT thread. It is built for plumbing and pipe-fitting projects that require a step-down in pipe size. The fitting suits installers working with standard FNPT connections.

Installation and Common Issues

Thread the coupling onto clean male NPT ends using appropriate sealant or tape for a leak-free joint. Over-tightening can crack the PTFE body, while debris on threads often causes seepage. Ensure both pipe ends match the stated FNPT sizes before assembly.

Suitable Uses and Limitations

This coupler fits systems needing a direct reduction between the two specified FNPT diameters. It does not serve applications requiring a different thread standard, a larger step-down ratio, or a material other than PTFE. Buyers needing other connection types or dimensions should select a different fitting.

Questions about this item

How can I confirm the reducer coupling seals properly after threading it onto 2" and 1/2" FNPT pipes?

Tighten the white PTFE coupling onto both FNPT threads, then pressurise the system and check each joint for leaks; a dry, drip-free connection shows it is working as intended.

What comes in the box and do I need to buy thread sealant or tape separately?

The box contains the single 2" x 1/2" FNPT reducer coupling; PTFE thread tape or pipe dope is not included and must be purchased separately for a reliable seal.

Which version of this reducer coupling should I choose for a 2" female pipe reducing to 1/2" female pipe?

Select the white PTFE reducing coupling with FNPT threads on both ends, identified by part number 810089805, which matches the 2" to 1/2" size reduction.
