A 316 stainless steel hex bushing reducing MNPT 1-1/2 in to FNPT 1-1/4 in at Class 150 pressure rating

  • Reduces 1-1/2 in male to 1-1/4 in female NPT threads
  • 316 stainless steel resists corrosion across air, gas, water, oil and steam
  • Class 150 rating handles 300 psi operating and 150 psi steam pressure
  • 7 mm hex flats allow secure wrench engagement during installation
  • Meets ANSI B1.20.1 and low-lead rules for potable water systems

1-1/2 in MNPT to 1-1/4 in FNPT Bushing

This 316 stainless steel hex bushing reduces a 1-1/2 inch male NPT thread to a 1-1/4 inch female NPT thread. It is designed for piping systems requiring a durable, corrosion-resistant transition between these two nominal sizes. The fitting carries a Class 150 pressure rating with a maximum operating pressure of 300 psi. It complies with ANSI B1.20.1 threading standards.

Suitable Fluids and Incompatible Needs

The material and threading suit air, natural gas, non-potable water, oil, potable water, and steam service up to 150 psi steam pressure. Low-lead compliance supports potable water installations. Buyers needing a different thread standard, a larger or smaller reduction step, or a material other than 316 stainless steel should look at alternative fittings. Systems exceeding the Class 150 pressure envelope require a higher-rated component.

51.7 mm Hex and Schedule 40 Fit

The hex measures 51.7 mm across flats, providing the wrench engagement needed for installation torque. Overall length is 35 mm. The bushing is compatible with Schedule 40 pipe dimensions. Verify that the available wrench clearance and pipe schedule match these figures before purchase.
