Easy Alignment Coupling for Pipe Systems

This Anvil 0320201791 coupling connects pipe sections using a steel body rated to Class 150. It suits installers who need a straight FNPT joint on 3/4 in pipe without specialised tools. The design simplifies alignment during assembly for drainage and general piping work. Buyers needing larger diameters or different thread types should select another fitting.

Class 150 Pressure and Temperature Limits

The coupling withstands 150 psi at 450 Degrees F and operates from -20 Degrees to 150 Degrees F. These bounds define safe service for steam, water or compatible fluids in standard plumbing circuits. Systems running above 150 psi or beyond the stated temperature range require a higher-class component. The API Specification 5L listing confirms the material standard for the pressure envelope.

Steel Construction and FNPT Connection

The steel body resists mechanical stress and corrosion in typical indoor and protected outdoor runs. Female National Pipe Thread ends accept standard male pipe threads for a sealed joint without welding. The Easy Alignment feature reduces cross-threading risk during hand tightening. Installers should verify thread compatibility and apply appropriate sealant for the service fluid.

Questions about this item

What does the Class 150 rating mean for this 3/4 in steel coupling?

Class 150 indicates a maximum working pressure of 150 psi at 450 °F, so the coupling is rated for that pressure and temperature combination in service.

How does the 150 psi @ 450 °F rating translate to everyday plumbing use?

The coupling handles up to 150 psi at temperatures up to 450 °F, and the listed range extends down to -20 °F, covering typical hot-water and steam lines.

What does the FNPT connection type on this coupling cap in practice?

FNPT means female National Pipe Taper threads; the connection seals on the thread taper and is limited to the coupling's 150 psi / 450 °F rating.
