Value Brand 1/2" MNPT x MNPT Black Pipe Nipple Schedule 40 1.5 in

Black Steel Pipe Nipple 1/2" MNPT

This black steel pipe nipple connects two female NPT fittings in plumbing and gas systems. It meets ASTM A-53 Type E and ASTM A-733 Grade B standards for Schedule 40 welded pipe. The electric resistance weld construction provides reliable strength for residential and light commercial installations. Builders and maintenance technicians use it to extend or join threaded pipe runs.

Sustained Pressure Rating 300 psi

The fitting handles a maximum working pressure of 300 psi at 150 degrees Fahrenheit during continuous operation. Its Schedule 40 wall thickness of 109/1000 inch maintains structural integrity under constant load without deformation. The welded seam meets Grade B specifications for long-term durability in water, air, and oil lines. Steam service is rated separately at 150 psi WSP for heating applications.

Threaded Ends Seal Without Gaskets

Tapered MNPT threads on both ends create a metal-to-metal seal when tightened, eliminating the need for separate gaskets or O-rings. The 53/64 inch outside diameter fits standard 1/2 inch nominal pipe tooling for quick assembly. Black steel construction resists mechanical damage during installation and service. The 1.5 inch overall length suits tight connections where space is limited.
