1-1/4" x 1/2" 304 SS Hex Bushing

This 304 stainless steel hex bushing reduces a 1-1/4 inch male NPT thread down to a 1/2 inch female NPT thread. It suits plumbing and industrial piping systems requiring a durable, corrosion-resistant transition between different pipe sizes. The fitting meets Class 150 pressure ratings for general service.

Class 150 rated 300 psi working pressure

Constructed from 304 stainless steel conforming to ASTM A351, the bushing withstands a maximum working pressure of 300 psi and a maximum steam pressure of 150 psi. Threads conform to ANSME B1.20.1 standards. The hex profile allows secure installation with a standard wrench for reliable, leak-free joints.

Verify thread sizes and pressure needs

Confirm your system uses male NPT threads on the larger side and requires a female NPT connection on the reduced side. Ensure the 300 psi pressure rating and 150 psi steam limit match your application requirements. This fitting is not intended for systems exceeding these pressures or for non-NPT thread standards.

Questions about this item

What pressure does the Class 150 rating cap this bushing at?

The Class 150 rating limits the bushing to 300 psi maximum pressure and 150 psi maximum steam pressure.

What wrench size fits the hex on this 1-1/4 in by 1/2 in bushing?

The hex flats match standard 1-1/4 in pipe dimensions; use a wrench sized for that nominal pipe size to avoid rounding the corners.

How do you seal the MNPT threads without cracking the FNPT port?

Apply PTFE tape or pipe dope on the male threads only, then tighten one to two turns past hand-tight — over-torquing the female port is the common mistake.
