Value Collection B300 10 300 End Cap 3/8 in Threaded Class 300

Product Description

The VALUE COLLECTION B300 10 300# is a threaded malleable iron end cap used to close off the end of a pipe run in gas and liquid piping systems. Finished in black, this fitting meets Class 300 standards and carries ratings for both ANSI/ASME B1.20.1 and ASME B16.3, confirming dimensional and pressure conformance. With a 1500 psi pressure rating, it is suited for demanding service conditions in commercial and industrial piping. The 3/8 inch threaded connection allows straightforward installation with standard pipe threading tools. Plumbers, pipefitters, and gas fitters install this fitting as a permanent or serviceable end closure on threaded pipe assemblies.

This end cap is appropriate for residential and commercial piping systems carrying gas or liquid media. The 3/8 inch size fits common branch and service line diameters found in gas distribution, steam, and water piping. The threaded connection style suits schedule 40 and schedule 80 pipe systems where NPT fittings are standard. It is a practical choice for capping unused outlets, test ports, and branch tees during system installation or modification.

Installation Notes

This fitting is installed by licensed plumbers, pipefitters, or gas fitters working under applicable codes including IFGC and IPC. Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten to a firm, leak-free connection using a pipe wrench. Do not overtighten malleable iron fittings, as the material can crack under excessive torque.
