Value Brand Reducing Coupling Malleable Iron 3/4 NPT x 1/2 NPT Class 150

SKU CH-64RF-WBZY9

Malleable iron reducing coupling joins 3/4 NPT to 1/2 NPT female threads in Class 150 galvanised finish

  • Reduces pipe size from 3/4 to 1/2 NPT
  • Malleable iron construction handles Class 150 pressure rating
  • Galvanised finish resists corrosion in plumbing systems
  • Female NPT threads on both ends ensure secure connections
  • Brand new ZORO SELECT fitting ready for installation

Reducing Coupling 3/4 NPT to 1/2 NPT

This galvanised malleable iron reducing coupling connects a 3/4 inch NPT female thread to a 1/2 inch NPT female thread. It is rated for Class 150 service in plumbing and piping systems. The fitting suits installers who need a straight, durable transition between two different pipe sizes.

Replaces worn or mismatched threaded joints

Use this coupling when an existing 3/4 inch female port must accept a 1/2 inch male pipe or fitting. The jump is worth it whenever a reducer bushing would leave insufficient thread engagement or when a straight coupling keeps the run aligned without extra elbows.

Holds pressure under continuous service

Malleable iron construction resists cracking under sustained pressure and thermal cycling better than cast iron alternatives. The galvanised coating protects the threads during long-term exposure to moisture. Thread count of 14 per inch ensures a tight seal that remains stable under constant load.

Questions about this item

What thread sizes does the 3/4 NPT x 1/2 NPT reducing coupling use?

The coupling has a 3/4 inch female NPT thread on one end and a 1/2 inch female NPT thread on the other, both with 14 threads per inch.

How do I install this malleable iron reducing coupling without damaging the threads?

Apply PTFE tape or pipe thread sealant to the male threads only, then hand-tighten before using a wrench for one to two turns; over-tightening can crack the Class 150 iron.

Will the galvanized coating on this Class 150 coupling need replacement over time?

The galvanized finish protects the malleable iron from corrosion; inspect periodically for white rust or red rust, and replace the fitting if the coating is breached or threads show leakage.
