Value Collection B300 25 300 Threaded End Cap 1 Inch Class 300

Product Description

The VALUE COLLECTION B300 25 300# is a Class 300 black malleable iron threaded end cap designed to close off the end of a threaded pipe run. Rated to 1500 psi for liquid and gas service, this fitting meets ANSI/ASME B1.20.1 and ASME B16.3 standards, making it a code-compliant choice for demanding piping applications. The black finish is standard for gas and industrial piping systems. At 0.56 pounds, the cap is sized for 1 inch threaded connections and is sold individually. Plumbers, pipefitters, and gas fitters rely on this class of fitting for secure, pressure-rated pipe terminations.

This end cap is suited for residential and commercial piping systems where a threaded termination point is required. Common applications include natural gas distribution lines, compressed air systems, steam lines, and industrial fluid piping where Class 300 malleable iron fittings are specified. The black finish is the industry standard for gas service piping, and the Class 300 rating gives it a significant pressure margin over standard Class 150 fittings, making it appropriate for higher-pressure installations.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas fitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), and the International Plumbing Code (IPC). Shut off and depressurize the pipe system completely before installing or removing any threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium before threading the cap onto the pipe. Do not overtighten; use a properly sized pipe wrench and follow standard trade practice for malleable iron fittings.
