Reducing Coupling 2 in x 1/2 in FNPT

This malleable iron reducing coupling connects a 2 inch female NPT pipe to a 1/2 inch female NPT pipe. It is rated for Class 300 service in plumbing and piping systems. The fitting is supplied new and ready for installation.

Replaces direct-size couplings and bushings

Use this reducer when joining pipes of different diameters without adding extra fittings. The jump is worth it when a single transition piece saves labour and potential leak paths compared to multiple adapters. It suits systems threaded to NPT standards with 11 1/2 and 14 threads per inch respectively.

Handles Class 300 pressure duties

The malleable iron body provides the mechanical strength required for Class 300 rated piping. It comfortably handles the pressure and temperature range implied by that class. Headroom ends where system pressure exceeds the Class 300 rating or where non-NPT threads are encountered.

Questions about this item

Will the 2 in FNPT end with 11 1/2 threads per inch match my existing pipe?

Yes, the larger end uses 2 in FNPT with 11 1/2 threads per inch, a standard taper thread for Class 300 malleable iron fittings.

Do I need thread sealant on both the 2 in and 1/2 in FNPT connections?

Apply PTFE tape or pipe dope to the male threads before engaging either FNPT end; the 1/2 in side has 14 threads per inch, so wrap clockwise three to four turns.

How often should I inspect the malleable iron body for corrosion?

Check annually for rust or scale, especially if the water supply is acidic; replace the coupling if wall thickness shows visible loss or leaks appear at the threads.
