Value Collection -12128-2 3/8 Inch Npt Pipe Cap Class 3000

Product Description

The VALUE COLLECTION -12128-2 is a forged carbon steel pipe cap designed to close off the end of a threaded pipe run. Finished in black and rated to Class 3000, this cap handles high-pressure liquid and gas service up to 3000 psi. The 3/8 inch NPT female thread seats securely on standard tapered male pipe threads, creating a leak-resistant termination point. It is a standard component in pressure piping systems where a permanent or semi-permanent dead end is required. Plumbers, pipefitters, and mechanical contractors install this type of fitting during new construction, system modifications, or pressure testing procedures.

This cap is suited for use in residential and commercial piping systems handling liquids or gases at elevated pressures. The Class 3000 rating makes it appropriate for steam, compressed air, oil, natural gas, and hydraulic service lines where a standard Class 150 or 300 fitting would be undersized. It is a common stock item used when capping unused branch outlets, isolating a section of pipe, or completing a pressure test setup.

Compatibility

Designed as an OEM-style replacement and standard stock fitting compatible with 3/8 inch NPT male-threaded pipe ends in Class 3000 rated pressure piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable code requirements such as the International Plumbing Code or ASME B16.11 for forged fittings. Isolate and depressurize the piping system fully before threading on the cap. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not overtighten, as forged fittings can crack the mating pipe thread if excessive torque is applied with power tools.
