Value Collection B300 8 300 End Cap 1/4 in Threaded Class 300

Product Description

The VALUE COLLECTION B300 8 300# is a threaded malleable iron end cap rated for Class 300 service. It accepts a 1/4-inch threaded pipe connection and is finished in black. End caps of this type are used to close off the terminal end of a threaded pipe run, providing a secure, pressure-rated seal. Conforming to ANSI/ASME B1.20.1 and ASME B16.3 standards, this fitting carries a liquid and gas pressure rating of 1500 psi, making it suitable for moderate- to high-pressure piping systems. Plumbers, pipefitters, and mechanical contractors typically install this type of fitting in gas, steam, air, or liquid distribution lines.

This end cap is appropriate for residential and commercial piping applications where a threaded closure is required on a 1/4-inch pipe end. Common install scenarios include capping unused branch outlets, temporary or permanent line terminations, and maintenance shutoffs on compressed air, gas distribution, or hydronic systems. The black finish is standard for gas piping installations and is consistent with conventional malleable iron fitting practice.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as appropriate. Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly to ensure a leak-free connection. Do not overtighten; inspect for leaks after restoring system pressure.
