  • Corrosion-resistant 316 stainless steel construction for demanding fluid and gas lines
  • Male 2 inch NPT to female 1-1/4 inch NPT reduces pipe size securely
  • Hexagonal 62.5 mm profile allows standard wrench tightening for leak-free joints

  • Manufactured to MSS-SP-114 and ASME B1.20.1 standards ensuring thread compatibility

Reducing Bushing for Pipe Transitions

This hex reducing bushing connects a 2 inch male NPT pipe or fitting to a 1 1/4 inch female NPT counterpart. It is machined from 316 stainless steel that meets ASTM A351 standards for corrosion resistance. The fitting suits installers who need a durable transition between different pipe diameters in fluid or gas systems.

Class 150 Rating and Wrench Flats

Rated for Class 150 pressure specifications, the bushing handles steam, air, natural gas, oil, potable water and non-potable water within the limits of that class. Its 62.5 mm hex flats accept a standard wrench for secure tightening without damaging the fitting. Threads conform to ASME B1.20.1 and MSS SP 114 standards for reliable sealing.

Sustained Service in Corrosive Media

The 316 stainless steel body resists corrosion during continuous exposure to aggressive fluids and elevated temperatures allowed by the Class 150 rating. An overall length of 35.5 mm keeps the installed profile compact while maintaining full thread engagement. No thread sealant is pre-applied, so the installer selects a compound matched to the specific medium and operating conditions.

Questions about this item

What is the maximum pressure class this 316 stainless steel bushing is rated for?

The bushing is rated for use within Class 150 pressure specifications according to MSS-SP-114 standards.

How much heat does the fitting generate during continuous steam service?

The fitting itself generates no heat; it conducts the temperature of the steam flowing through it, and 316 stainless steel resists corrosion at those temperatures.

Which wrench size fits the 62.5 mm hex on this reducing bushing?

A 62.5 mm wrench or adjustable spanner fits the hex flats for tightening the 2 inch male NPT into the mating fitting.
