Value Collection -12128-1 Pipe Cap 1/4 Inch Npt Class 3000

Product Description

The VALUE COLLECTION -12128-1 is a forged carbon steel pipe cap designed to close off open pipe ends in high-pressure piping systems. Rated at 3000 psi and manufactured to Class 3000 standards, this cap is built for demanding industrial and mechanical applications where pressure integrity is critical. The black finish provides basic corrosion resistance during storage and installation. With a 1/4 inch NPT female thread connection, it threads directly onto male-threaded pipe ends to provide a secure, pressure-rated termination. Plumbers, pipefitters, and mechanical contractors working on gas and liquid distribution systems rely on caps like this for system pressure testing and permanent branch closures.

This cap is suited for use in residential and commercial piping systems carrying liquids or gases within the 3000 psi pressure rating. Its compact 1/4 inch size makes it a common choice for terminating small-diameter branch lines, capping test ports, or sealing unused outlets in manifold assemblies. The NPT thread form is the standard for pipe fittings across North American plumbing, HVAC, and industrial piping systems, making this cap broadly applicable in those environments. Sold in packages of 5 units per package.

Key Features

Compatibility

Designed as an OEM-style replacement or standard-use fitting for 1/4 inch NPT male-threaded pipe ends in Class 3000 carbon steel piping systems handling liquid or gas service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as relevant to the service. Depressurize and isolate the piping system completely before installing or removing any threaded fitting. Apply appropriate thread sealant or PTFE tape to the male threads before threading on the cap. Do not over-tighten; use a pipe wrench with steady, controlled force and confirm no leaks under pressure before returning the system to service.
