2 inch x 3 inch Black Steel Nipple

2" x 3" Black Steel Nipple – Schedule 40, Threaded Ends

The 2" x 3" Black Steel Nipple is designed for use in industrial and commercial piping systems requiring strong, pressure-rated connections. Manufactured from welded Schedule 40 black steel pipe, this nipple features precision-machined NPT threads on both ends to provide a secure, leak-resistant seal when installed with compatible fittings.

Commonly employed in steam, oil, water, and gas applications, this short-length nipple is ideal for connecting pipe segments, adapting to valves or fittings, or making equipment tie-ins in systems operating under moderate pressure. The black oxide finish provides a clean surface suitable for use in indoor, non-corrosive environments.
