The ASC Engineered Solutions 390030229 is a grooved painted cap designed to terminate the end of a grooved pipe system. It installs at the end of a pipe run to seal off flow and pressure within the line. Constructed from ductile iron and finished with a painted coating for corrosion resistance, this cap is suited for mechanical piping systems found in commercial HVAC, fire protection, and industrial plumbing applications. Weighing 2.46 pounds and sized for 4-inch grooved pipe, it provides a durable, pressure-rated termination point. Licensed pipefitters and mechanical contractors typically install this fitting as part of a grooved mechanical coupling system.
This grooved cap is used in commercial and industrial piping systems where a grooved-end pipe termination is required. Common applications include chilled water, heating hot water, condenser water, and fire sprinkler distribution systems. The 4-inch size fits standard grooved pipe ends and connects using a standard grooved mechanical coupling, eliminating the need for threading or welding at the termination point.
Designed as an OEM-style replacement or new-installation grooved pipe cap for use with standard 4-inch grooved mechanical piping systems in commercial HVAC, fire protection, and industrial plumbing applications.
Installation is performed by licensed pipefitters or mechanical contractors familiar with grooved piping systems. Isolate and depressurize the affected pipe section and drain the line before installing or replacing the cap. A standard grooved coupling and the appropriate gasket for the service medium are required to complete the connection. Follow applicable codes including NFPA 13 for fire protection systems and local mechanical codes for HVAC and plumbing applications.
