Asc Engineered Solutions 390039766 Grooved Fpt Adapter 3 in

Product Description

The ASC Engineered Solutions 390039766 is a GRUVLOK 7087 series grooved x female pipe thread (FPT) adapter designed to transition between grooved-end piping and threaded pipe connections in mechanical piping systems. Built from ductile iron, this 3-inch adapter delivers the structural integrity required for commercial and industrial piping installations where grooved couplings meet threaded fittings. Licensed plumbers, pipefitters, and mechanical contractors install this fitting in hydronic, fire protection, and process piping systems that combine grooved and threaded components.

This adapter is suited for applications in commercial buildings, industrial facilities, and institutional projects where grooved piping infrastructure connects to threaded branch lines, valves, or equipment ports. The 3-inch size fits mid-range piping runs common in HVAC hydronic loops, chilled water systems, and fire sprinkler mains. It is part of the established GRUVLOK 7087 product family, which is a recognized standard in grooved mechanical piping.

Key Features

• Ductile iron construction provides high strength and impact resistance for demanding piping environments
• Grooved inlet end is compatible with standard grooved coupling systems for tool-free mechanical joining
• Female pipe thread (FPT) outlet transitions the grooved system to standard threaded pipe fittings or equipment
• 3-inch fitting size fits common mid-range commercial and industrial piping runs
• Part of the GRUVLOK 7087 series, a widely used standard in mechanical and fire protection piping

Compatibility

Designed as an OEM-style grooved piping adapter for use with standard 3-inch grooved mechanical coupling systems and standard female pipe thread connections in commercial and industrial piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes, including IFGC and IPC references where applicable. Depressurize and drain the piping system fully before removing or installing any grooved or threaded fittings. Verify that groove dimensions on the pipe end conform to the manufacturer specification for the GRUVLOK coupling being used. Apply appropriate thread sealant or PTFE tape to the FPT connection per standard practice before making up the threaded joint.
