Value Collection B300 25 Black Iron End Cap 1 in Threaded

Product Description

The VALUE COLLECTION B300 25 is a threaded black malleable iron end cap rated for Class 150 service. It is designed to close off the open end of a threaded pipe run, preventing flow and protecting the line from contamination or damage. Built to ANSI/ASME B1.20.1 and ASME B16.3 standards, this fitting handles liquid and gas service up to 300 psi. The black finish is standard for gas distribution and low-pressure steam systems. Plumbers, pipefitters, and mechanical contractors install this fitting in new construction, retrofit, and maintenance applications where a reliable, code-compliant pipe closure is required.

This end cap is suited for residential and light commercial piping systems carrying gas, air, water, or steam at low to moderate pressures. The 1 inch threaded connection fits standard NPT pipe. It is commonly used in gas supply lines, compressed air systems, and hydronic heating systems where a threaded pipe termination must be capped and sealed. The malleable iron construction provides the strength and ductility required for threaded pipe assemblies in mechanical rooms, utility spaces, and underground service conditions.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1 inch NPT threaded malleable iron pipe systems in Class 150 gas, water, air, and steam applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC, and ASME B31 piping standards. Shut off and depressurize the pipe system fully before installing or removing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not overtighten; use a pipe wrench with a backup wrench on adjacent fittings to avoid stressing upstream joints.
