3/8" Red Brass Nipple for High-Pressure Lines

The Zoro Select 462-080X is a Schedule 80 pipe nipple built from seamless red brass to ASTM B43 grade. It carries a 3/8 inch nominal bore and an 8 inch overall length with male NPT threads on both ends. The fitting suits air, natural gas, oil, potable water and steam systems in commercial and industrial piping.

Sustained Pressure and Temperature Performance

Rated for 276 psi at 450 degrees F, the nipple holds its seal under continuous steam or hot-water service up to 400 degrees F. The seamless red brass construction resists stress corrosion and erosion during long duty cycles without the fatigue seen in welded alternatives. Minimum operating temperature reaches -20 degrees F for cold-environment installations.

Class 300 Compatibility and Proposition 65 Notice

Threads conform to Class 300 fitting compatibility, matching standard heavy-pattern flanges and valves in the same pressure class. The 43/64 inch outside diameter fits corresponding couplings without adapters. California Proposition 65 warnings apply because the alloy contains a listed chemical; the restriction list for this item is currently empty.

Questions about this item

How hot does the red brass nipple get when steam runs through it at 276 psi all day?

The nipple is rated for a maximum operating temperature of 400 degrees F and a maximum steam pressure of 276 psi at 450 degrees F, so it handles continuous steam service within those limits.

Which fittings or pipe do I already need to connect this 3/8 inch MNPT nipple?

It has 3/8 inch MNPT threads on both ends and a Class 300 fitting compatibility, so you need matching 3/8 inch FNPT fittings or pipe rated for Class 300 service.

Will this Schedule 80 nipple thread onto older Schedule 40 brass pipe I have in place?

Both use the same 3/8 inch NPT thread form, so it will thread on, but the Schedule 80 nipple has a thicker wall and smaller inside diameter than Schedule 40 pipe.
