The ASC ENGINEERED SOLUTIONS 318900800 is a 2.5-inch black cast iron pipe cap designed to terminate the end of a threaded pipe run. Cast iron construction provides the durability and pressure handling expected in demanding plumbing, mechanical, and fire protection applications. The black coating is factory-applied and suited for exposed and concealed installations. Licensed plumbers and pipefitters install this fitting as part of threaded piping assemblies where a permanent or serviceable end closure is needed.
This cap is appropriate for residential and commercial threaded black iron pipe systems, including gas distribution, compressed air, steam, and hydronic applications where cast iron fittings are specified. Its 2.5-inch fitting size fits standard Schedule 40 and Schedule 80 black iron pipe of the same nominal diameter. Domestically produced, it meets the sourcing expectations of projects requiring domestic content compliance.
Designed as an OEM-style replacement or new-installation fitting for 2.5-inch threaded black iron pipe systems.
Installation is performed by a licensed plumber or pipefitter. Thread sealant or PTFE tape rated for the intended service should be applied to the male pipe threads before installing the cap. Shut off and depressurize the piping system fully before making any threaded connections or removals. For gas service, all work must comply with applicable local codes and IFGC requirements.
