The ASC Engineered Solutions 390030302 is a grooved painted cap designed to terminate the end of a grooved pipe in mechanical piping systems. Manufactured from ductile iron and finished with a protective paint coating, this cap installs using standard grooved coupling hardware to seal off a 6-inch pipe end. It is well suited for HVAC, fire protection, and industrial piping applications where a secure, leak-resistant pipe termination is required. Licensed pipefitters and mechanical contractors are the primary installers of this fitting in both new construction and retrofit piping systems.
This grooved cap is intended for use on 6-inch grooved pipe systems in commercial and industrial environments. The grooved end connection method eliminates the need for welding or threading at the termination point, allowing for faster installation and future serviceability. It is a common component in mechanical rooms, rooftop HVAC equipment connections, and process piping layouts where grooved-end fittings are the specified joining method.
Designed as an OEM-style grooved fitting for use with standard grooved coupling systems on 6-inch nominal pipe in commercial mechanical and industrial piping installations.
Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical codes. Depressurize and drain the piping system completely before installing or removing any grooved fittings. Verify that the pipe end groove dimensions conform to the specifications required by the grooved coupling manufacturer before assembly. Inspect the gasket seat and coupling housing for damage prior to final torquing of the coupling fasteners.
