Anvil 2" x 1-1/2" Malleable Iron Hex Bushing

This Anvil hex bushing reduces a 2-inch female NPT opening to a 1-1/2-inch male NPT thread. It is built for plumbing and piping systems that require a durable, pressure-rated transition between different pipe sizes. The Class 150 malleable iron construction suits commercial and industrial installations where threaded connections are standard. Installers working with steam, water, gas or oil lines will find the fitting matches typical system requirements.

Sustained pressure and temperature performance

The fitting is rated for a maximum pressure of 300 psi at 150 degrees F and handles saturated steam up to 150 psi at 350 degrees F. Its service temperature range extends from -20 degrees to 350 degrees F, so it maintains integrity under continuous thermal cycling. These ratings reflect the ASME B 16.3 standard to which the bushing is manufactured, giving engineers a reliable baseline for long-term system design. It is not intended for pressures or temperatures beyond the listed limits.

Malleable iron build with hex driving flats

The Class 150 malleable iron body resists cracking under mechanical stress and vibration better than cast iron alternatives. External hex flats allow a standard pipe wrench to apply torque without damaging the fitting, speeding up installation and future maintenance. FNPT x MNPT threads seal with pipe compound or tape on standard NPT threads, so no proprietary tools or adapters are required. The fitting carries UL and FM approvals, confirming compliance with recognised safety standards for the listed applications.

Questions about this item

Does the Anvil 0318907680 hex bushing generate noise or heat when used continuously at 300 psi and 150°F?

The malleable iron construction and FNPT x MNPT threads contain no moving parts, so the fitting produces no operational noise or self-generated heat under the rated 300 psi at 150°F.

What existing pipe threads must be present to install the 2 in x 1-1/2 in FNPT x MNPT bushing?

You need a female NPT thread on the 2-inch side and a male NPT thread on the 1-1/2-inch side; the bushing simply threads between them.

Will this Class 150 malleable iron bushing mate with older ASME B16.3 fittings already in the system?

Yes, the Anvil 0318907680 meets ASME B16.3, so it threads directly onto legacy Class 150 malleable iron fittings of matching NPT size.
