- Connects 1" female to 3/4" male NPT threads
- 304 stainless steel resists corrosion in harsh environments
- Hex profile allows secure tightening with standard wrench
- Rated 3000 psi at 100°F for high-pressure systems
- Meets ASTM-A-182, ASME B16.11, ANSI/ASME B1.20.1 standards
Hex Reducing Bushing – 1" FNPT to 3/4" MNPT
This 304 stainless steel hex reducing bushing connects a 1 inch female NPT opening to a 3/4 inch male NPT thread. The hexagonal profile allows tightening with a standard wrench for secure pipe joints. It meets ASTM A182 material specification and ASME B16.11 dimensional standards. Thread sealant is not included and must be sourced separately.
Pressure rating and thread detail
Rated for 3000 psi at 100°F and 2500 psi steam pressure at 350°F under Class 3000 service. Male threads are cut to 11 1/2 TPI while female threads use 14 TPI per ANSI/ASME B1.20.1. The 304 stainless steel construction resists corrosion in water, oil and mild chemical lines. California Proposition 65 warnings apply for cancer and reproductive harm.
Deciding specification – pressure class
The Class 3000 rating determines whether this fitting suits the system’s maximum working pressure and temperature. Installers must verify that 3000 psi at 100°F or 2500 psi at 350°F steam covers the application. Buyers needing higher pressure classes or different thread standards should select another fitting.

Questions about this item
How do I install the 1" female NPT x 3/4" male NPT hex reducing bushing and what step is often missed?
Apply thread sealant to the NPT threads before tightening the hex with a wrench; sealant is not included and skipping it causes leaks.
What maintenance or replacement will the 304 stainless steel Class 3000 reducing bushing need over time?
Inspect threads and sealing surfaces periodically for corrosion or deformation; replace the fitting if thread damage or leakage appears.
What is the first pressure limit reached on the 11 1/2 TPI male and 14 TPI female threads under sustained high-temperature use?
The maximum steam pressure of 2500 psi at 350°F is reached before the 3000 psi water rating at 100°F.
