Hexagonal 316 stainless steel reducing bushing with male and female threaded ends

Value Brand

Value Brand 2" x 1-1/2" MNPT x FNPT 316 SS Hex Reducing Bushing

SKU CH-9ZRR-2HQXF

Connects a 2-inch female NPT opening to a 1-1/2-inch male NPT thread using 316 stainless steel rated for 3000 psi at 100°F

  • Corrosion-resistant 316 stainless steel meets ASTM A182
  • Hex flats enable secure wrench tightening during installation
  • 3000 psi rating at 100°F handles high-pressure systems
  • ANSI/ASME B1.20.1 threads ensure reliable sealed connections
  • Reduces 2" FNPT to 1-1/2" MNPT for pipe adaptation

2-Inch to 1-1/2-Inch Hex Reducing Bushing

This 316 stainless steel hex reducing bushing connects a 2-inch female NPT opening to a 1-1/2-inch male NPT pipe or fitting. It conforms to ASTM-A-182 and ANSI/ASME B1.20.1 thread standards. The fitting is designed for wrench tightening via its hexagonal outer profile. It suits industrial plumbing systems requiring a durable size transition.

Sustained Pressure and Temperature Limits

The bushing carries a Class 3000 rating with a maximum pressure of 3000 psi at 100°F. For steam service the maximum pressure is 2500 psi at 350°F. These ratings reflect continuous operating limits rather than short-term burst values. The 316 stainless steel construction maintains integrity under prolonged thermal and mechanical stress.

NPT Thread Compatibility and Sealing Requirements

Threads follow the ANSI/ASME B1.20.1 taper standard and the fitting meets ASME B16.11 dimensions. No thread sealant is pre-applied and none is included, so the installer must supply appropriate tape or compound. The connection relies on proper thread engagement and sealant to achieve the rated pressure seal. It will not seal on parallel threads or without sealant.

Questions about this item

Does the 316 stainless steel fitting generate noise or heat when fluid runs through it all day?

The bushing is a passive component with no moving parts, so it produces no noise or heat of its own during continuous flow.

What thread sealant or tape must I already have to install this hex reducing bushing?

No pre-applied sealant is included, so you will need PTFE tape or pipe-thread compound compatible with 316 stainless steel and NPT threads.

Will the NPT threads on this 316 SS bushing match the NPT ports on my existing piping?

Threads conform to ANSI/ASME B1.20.1, the standard for NPT, so they will engage any matching NPT male or female port.
