Value Collection B300 100 Black End Cap 4 in Threaded

Product Description

The VALUE COLLECTION B300 100 is a threaded black malleable iron end cap designed to close off the end of a 4-inch threaded pipe. It is used to terminate pipe runs in piping systems carrying liquids or gases, with a pressure rating of 300 psi. The black finish is standard for gas and industrial piping applications. Manufactured to Class 150 standards and conforming to ANSI/ASME B1.20.1 and ASME B16.3, this fitting is appropriate for commercial and industrial installations where code-compliant fittings are required. It is installed by licensed plumbers, pipefitters, and mechanical contractors.

This end cap is suited for use in gas distribution piping, water supply systems, industrial process lines, and fire protection piping where a threaded termination is required. The 4-inch size fits standard NPT threaded pipe and is commonly used in both new construction and retrofit applications. Its malleable iron construction provides the durability needed in demanding mechanical and utility environments. This fitting ships as a single unit and is typically kept as a working stock item by plumbing and mechanical contractors.

Installation Notes

Installation is performed by licensed plumbers or pipefitters. Shut off system pressure and depressurize the line completely before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to the male threads before assembly, in accordance with local plumbing or mechanical codes. Tighten to snug plus hand-firm turns — do not over-torque malleable iron fittings, as they can crack under excessive force.
