Msi Products Inc A2040502 Malleable Iron Pipe Cap 1/8 in

Product Description

The MSI PRODUCTS INC A2040502 is a 150-pound class malleable iron pipe cap designed to close the end of male-threaded pipe. It provides a secure seal for system termination, pressure testing, or temporary shutoff in gas, steam, water, and air piping systems. Built to a heavy pattern design, this cap conforms to ASME B16.3 dimensional standards, ASTM A197 material specifications, and ASME B1.20.1 threading standards. The black finish indicates standard coating for malleable iron fittings. Licensed plumbers and pipefitters install these caps in both permanent and removable applications where maintaining system pressure integrity is required.

This cap is sized for 1/8-inch male-threaded pipe and is rated for use in systems operating within the 150-pound pressure class, appropriate for residential and light commercial piping. Typical applications include capping unused branch outlets, isolating sections during system testing, and providing temporary or permanent shutoffs in plumbing, HVAC, and steam distribution piping. Each fitting includes full lot traceability with material test reports available upon request, supporting quality and compliance requirements in inspected installations.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable codes such as the IPC and IFGC. Shut off and depressurize the system completely before removing or installing any threaded pipe cap. Apply appropriate thread sealant or PTFE tape to the male threads before threading on the cap. Do not over-tighten, as malleable iron fittings can crack under excessive torque.
