Galvanised malleable iron reducer coupling with female NPT threads

Value Brand

Value Brand 1-1/4" x 3/4" FNPT Galvanized Reducer Coupling

SKU CH-06ZR-C31XY

Galvanized malleable iron reducer coupling joins 1-1/4 inch and 3/4 inch FNPT pipes, rated 300 psi WOG and 150 psi steam, meeting ASME B16.3, B16.4, ASTM A197, A47, FM, NSF-61, AB1953 and UL standards

  • Reduces pipe from 1-1/4" to 3/4" for system flexibility
  • Galvanized malleable iron resists corrosion in water lines
  • Class 150 rating handles 300 psi at 150 °F
  • Meets ASME B 16.3, B 16.4, ASTM A197, A47 standards
  • NSF-61, AB1953, UL and FM listed for potable use

Pipe Size Reduction

The Value Brand galvanized malleable iron reducer coupling connects a 1-1/4 inch female NPT pipe to a 3/4 inch female NPT pipe. It is built to ASME B16.3 and B16.4 standards and carries FM, NSF-61, AB1953 and UL listings. The fitting suits water, oil and gas lines requiring a durable transition.

System Integration

The Class 150 rating allows use in standard residential and commercial plumbing assemblies. Female threads on both ends accept matching male NPT nipples or pipe lengths without adapters. Galvanized coating resists corrosion in potable water and compressed air systems. Installers must verify thread sealant compatibility with local codes.

Sustained Pressure Performance

Rated for 300 psi at 150 degrees Fahrenheit water, oil and gas service, the coupling maintains seal integrity under continuous operating loads. Saturated steam service is rated to 150 psi. The malleable iron body resists mechanical shock and vibration better than cast alternatives. It is not suited for pressures exceeding the stated limits.

Questions about this item

Will the Class 150 rating handle continuous 300 psi water pressure at 150 °F?

Yes, the fitting is rated for 300 psi WOG at 150 Degrees F and meets ASME B16.3 and B16.4 standards for sustained service.

Does the galvanized malleable iron run hot or leak during all-day steam use?

The coupling is rated for 150 psi saturated steam and FM approved, so it handles continuous steam duty without overheating or leaking.

Must the mating pipes already have FNPT threads to install this reducer?

Yes, both the 1-1/4 in and 3/4 in ends are FNPT, so the connecting pipes need matching male NPT threads.
