The ASC ENGINEERED SOLUTIONS 361188204 is a forged steel threaded cap designed to close off the end of a threaded pipe or fitting. Built to a 3000 lb pressure rating, this cap provides a reliable, pressure-rated termination point in high-demand piping systems. The 1/4 inch connection size makes it suited for smaller branch lines and instrument connections. Forged steel construction delivers the strength and durability required in industrial and commercial plumbing, oil and gas, and mechanical piping applications. Licensed plumbers and pipefitters are the primary installers of this fitting type.
This threaded cap is used in systems where a pipe end must be sealed permanently or temporarily during pressure testing, system isolation, or line capping. The 3000 lb pressure rating suits it for use in higher-pressure piping configurations common in commercial mechanical rooms, industrial process piping, and maintenance scenarios where a steel cap is required over a brass or plastic alternative.
Designed as an OEM-style replacement and standard fitment for 1/4 inch threaded pipe ends in 3000 lb class forged steel piping assemblies.
Installation is typically performed by a licensed plumber or pipefitter. Always depressurize and isolate the line before installing or removing a threaded cap. Apply an appropriate thread sealant or PTFE tape to the male threads before hand-tightening, then wrench-tighten to a secure fit. Follow applicable codes including ASME and local mechanical codes for threaded fitting installation in pressurized systems.
