Value Collection B300 20 300 End Cap 3/4 in Malleable Iron

Product Description

The VALUE COLLECTION B300 20 300# is a threaded malleable iron end cap designed to close off the end of a 3/4-inch threaded pipe run. Finished in black, this fitting meets Class 300 pressure standards and is rated for liquid and gas service up to 1500 psi. It conforms to ANSI/ASME B1.20.1 thread standards and ASME B16.3 malleable iron fitting specifications. Plumbers, pipefitters, and mechanical contractors install this type of fitting when terminating a branch line, capping an unused port, or pressure-testing a section of piping.

This end cap is suited for residential and light commercial piping systems carrying steam, gas, air, water, or other compatible media where a Class 300 malleable iron fitting is specified. The threaded connection makes it straightforward to install and remove without special tooling, which is useful in retrofit and maintenance situations where future access may be needed. It is commonly used in gas distribution, compressed air, and hydronic heating applications.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPT threaded malleable iron piping systems requiring a Class 300 end cap.

Installation Notes

A licensed plumber or pipefitter should install this fitting in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the pipe system completely before threading on or removing any fitting. Apply appropriate thread sealant or tape rated for the media being conveyed before making up the connection. Do not overtighten; use a pipe wrench sized for the fitting to avoid cracking the malleable iron.
