  • 3/4" MNPT to 1/2" FNPT adapts pipe sizes easily
  • Forged steel construction delivers mechanical strength under stress
  • Hex profile allows secure wrench tightening during installation

Galvanized Hex Bushing 3/4" MNPT x 1/2" FNPT

This galvanized hex bushing connects a 3/4 inch male NPT thread to a 1/2 inch female NPT thread. It is forged from steel and finished with a galvanized coating for corrosion resistance. The fitting carries a Class 3000 pressure rating. It suits plumbers and maintenance technicians reducing pipe sizes in water or air lines.

Sustained load behavior

The forged steel body and galvanized finish are built to handle continuous pressure up to the Class 3000 rating without deformation. Threads are cut to NPT standards for a reliable seal that holds under steady system pressure. The Zamak 3 die-cast construction provides structural integrity during prolonged thermal cycling. It resists the creep and leakage that can appear in lower-grade fittings over time.

Class 3000 pressure rating

This single specification defines the maximum working pressure the bushing can safely contain. Buyers must verify that their system pressure stays within this limit before installation. The rating also determines compatibility with applicable piping codes. Systems exceeding Class 3000 require a higher-rated fitting not supplied here.

Questions about this item

Does this galvanized hex bushing generate any noise or heat when installed in a continuously pressurised water line?

No, the fitting is a static forged-steel component with no moving parts, so it produces no operational noise or heat.

What existing pipe threads must be present for this 3/4 in male NPT by 1/2 in female NPT bushing to connect?

The system needs a 3/4 in female NPT opening and a 1/2 in male NPT pipe or fitting to accept the two ends.

Will the Class 3000 rating and galvanized finish hold up when joined to older galvanized pipe of the same thread standard?

Yes, both ends use standard NPT threads, so the bushing threads directly onto legacy galvanized pipe without adapters.
