Value Brand

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

SKU CH-5ZQR-KYT6T

Galvanized malleable iron hex bushing connects 2-1/2 inch male NPT to 3/4 inch female NPT for Class 150 plumbing at 300 psi

  • Reduces 2-1/2" male thread to 3/4" female thread for pipe transitions
  • Galvanized malleable iron resists corrosion in water and air systems
  • Rated 300 psi at 150 °F for high-pressure service
  • Meets ANSI B1.20.1 threading standard for reliable seal
  • Class 150 fitting handles saturated steam up to 150 psi

Connection Size and Thread Type

This galvanized malleable iron hex bushing connects a 2-1/2 inch male NPT thread to a 3/4 inch female NPT thread. It is designed for plumbing systems requiring a secure reduction between dissimilar pipe diameters. The fitting meets ANSI B1.20.1 specifications for thread dimensions and engagement.

Pressure and Temperature Limits

The Class 150 rating supports a maximum pressure of 300 psi at 150 degrees Fahrenheit for water, oil, or gas service. Saturated steam pressure is limited to 150 psi. Operating temperature range extends from minus 20 degrees to 150 degrees Fahrenheit, covering typical residential and commercial environments.

Capacity and Application Fit

The bushing comfortably handles standard water, oil, and gas distribution within the stated pressure and temperature envelope. It runs out when system pressure exceeds 300 psi or when steam pressure surpasses 150 psi. Installations requiring higher pressure ratings or temperatures above 150 degrees Fahrenheit need a different fitting class.

Questions about this item

Which size combination should I select for a 2-1/2" male pipe thread reducing to a 3/4" female thread?

This bushing provides exactly that reduction — 2-1/2" MNPT on one end and 3/4" FNPT on the other — so a single unit covers the transition you need.

What does the 300 psi rating mean when the fitting is installed in a water, oil or gas line?

It indicates the maximum non-shock working pressure at 150 °F; the fitting is also rated for 150 psi saturated steam within the same temperature range.

How does the ANSI B1.20.1 thread standard affect sealing on this galvanized malleable iron bushing?

The taper threads conform to ANSI B1.20.1, so they seal with pipe sealant or tape and engage fully in Class 150 galvanized malleable iron ports.
