Value Brand 1-1/4" x 3/4" MNPT x FNPT 304 SS Hex Reducing Bushing
A 304 stainless steel hex reducing bushing connects 1-1/4 inch female to 3/4 inch male NPT threads, rated to 3000 psi at 100°F and 2500 psi steam at 350°F
- 304 stainless steel resists corrosion and high temperatures
- Rated to 3000 psi at 100°F for high-pressure systems
- Withstands 2500 psi steam at 350°F in demanding environments
- Threads meet ANSI/ASME B16.11 for reliable sealing
- Hex profile allows secure tightening with a wrench
Threaded Pipe Adapter
This 304 stainless steel hex reducing bushing connects a 1-1/4" female-threaded pipe to a 3/4" male-threaded fitting. It is designed for industrial and commercial plumbing systems that require a secure transition between different nominal pipe sizes. The fitting meets Class 3000 pressure specifications and threads conform to ANSI/ASME B16.11 standards. It suits installers who need reliable corrosion and temperature resistance in threaded assemblies.
Replacing Mismatched Threads
Use this bushing when adapting an existing 1-1/4" female port to accept a 3/4" male pipe or component, eliminating the need for multiple separate fittings. The jump is worth it when a single-piece reduction simplifies assembly and reduces potential leak paths in high-pressure lines. It handles pressures up to 3000 psi at 100°F and steam pressures up to 2500 psi at 350°F. Do not select this fitting if the application requires a larger male thread or a different material grade.
Build Integration
The hex profile allows tightening with a standard wrench during installation into the female-threaded opening. The 304 stainless steel construction resists corrosion within specified environmental conditions, supporting system longevity. Ensure the mating threads match the ANSI/ASME B16.11 standard for a proper seal. This component frees up space by combining the reduction into one compact fitting rather than a nipple-and-coupling assembly.

Questions about this item
What size wrench fits the hex on this 1-1/4" x 3/4" reducing bushing?
The hex shape allows tightening with a standard wrench matched to the external hex flats on the 304 stainless steel body.
How do I seal the ANSI/ASME B16.11 threads when installing this 3000 psi rated bushing?
Apply PTFE tape or pipe thread sealant to the 3/4" male NPT threads only, then tighten into the female port without over-torquing the hex.
Will the 304 stainless steel require replacement due to corrosion in a 350°F steam system?
The 304 SS construction resists corrosion at the rated 2500 psi steam pressure and 350°F limit; inspect threads periodically for wear.
