1" x 1/2" 304 SS Reducing Bushing

This hex reducing bushing connects a 1 inch male NPT thread to a 1/2 inch female NPT thread. It is machined from 304 stainless steel for corrosion resistance in plumbing and industrial piping systems. The fitting conforms to material standard ASTM A-182 and meets ASME B16.11 for forged fittings.

Class 3000 rating for high-pressure lines

Rated for 3000 psi at 100 degrees F and 2500 psi steam pressure at 350 degrees F, this Class 3000 fitting suits demanding hydraulic and steam applications. Threads conform to ANSI/ASME B1.20.1 for reliable sealing with compatible pipe components. It requires matching NPT threads on adjacent pipe or fittings for proper assembly.

No gaskets or sealant included

The bushing ships as a single metal component without thread sealant, tape, or gaskets. Installers must supply appropriate pipe thread compound or PTFE tape to achieve a leak-free joint. No additional hardware or software accessories are bundled with this fitting.

Questions about this item

How long can the 304 stainless steel body hold 3000 psi at 100 degrees F before creep becomes the limiting factor?

The fitting is rated for 3000 psi at 100 degrees F under Class 3000 per ASTM-A-182; sustained use at that pressure and temperature stays within the material design limits.

Does the hex bushing radiate enough heat to require insulation when steam runs at 2500 psi and 350 degrees F continuously?

At 2500 psi steam and 350 degrees F the surface reaches steam temperature; personnel protection or process insulation is recommended per normal piping practice.

Which thread standard must the mating pipe and port follow so the MNPT x FNPT connection seals without leaks?

Threads conform to ANSI/ASME B 1.20.1 and the fitting meets ASME B 16.11, so both male and female ports must be cut to that same taper standard.
