Anvil International 0818900607 Black Malleable Cap 1 in

Product Description

The ANVIL INTERNATIONAL 0818900607 is a black malleable iron pipe cap rated at 150 PSI and manufactured lead free. It is used to close off the end of a threaded pipe run in gas, air, or low-pressure fluid piping systems. The fitting threads onto a male-threaded pipe end to seal it completely, preventing flow and protecting the threads during service or system modifications. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting as part of standard black iron pipe assemblies in commercial and residential applications.

This cap is suited for use on 1-inch black iron pipe systems in natural gas distribution lines, compressed air systems, and similar low-pressure piping applications. It is commonly installed during system modifications, pressure testing, or when capping off unused branch connections. The lead-free construction makes it appropriate for potable water-adjacent applications where lead-free compliance is required by local code, though installation teams should verify local authority having jurisdiction requirements before use. Note that this product is prohibited from shipping to California.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code or International Plumbing Code. Shut off and depressurize the pipe system completely before installing or removing any threaded cap. Apply appropriate thread sealant or PTFE tape rated for the intended service medium before threading the cap onto the pipe end. Do not overtighten, as malleable iron fittings can crack under excessive torque.
