Value Brand 1/2" MNPT x MNPT Black Pipe Nipple Schedule 40 3 1/2 in

1/2" Schedule 40 Black Steel Nipple

This 1/2 inch nominal pipe size nipple connects two female-threaded components in air, gas, non-potable water or oil lines. The carbon steel body features a black finish and electric resistance welded construction for structural integrity. Male NPT threads on both ends allow direct installation into compatible fittings without additional adapters. It is manufactured to Schedule 40 wall thickness standards for standard pressure service.

Rated for 300 psi at 150 Degrees F sustained

The fitting handles continuous operating pressure up to 300 psi at 150 Degrees F in liquid or gas service. For saturated steam applications the maximum working pressure is 150 psi at 350 Degrees F. The welded seam maintains strength under these sustained thermal and mechanical loads without the fatigue risk associated with threaded-only joints. California Proposition 65 warnings apply for chemical exposure during handling or installation.

Verify thread size and schedule match your system

Confirm the mating components use 1/2 inch NPT female threads and require Schedule 40 wall thickness before ordering. The outside diameter measures 53/64 inch, so check available clearance in tight assemblies. Ensure the 3 1/2 inch overall length fits the required spacing between connection points. This nipple is not suitable for potable water systems or pressures exceeding the stated ratings.
