Asc Engineered Solutions 390202042 Flange Adapter

Product Description

The ASC Engineered Solutions 390202042 is a grooved end flange adapter designed to connect grooved-end piping systems to flanged components. This fitting bridges two common pipe connection standards, allowing a grooved mechanical joint on one end to mate with a standard flange face on the other. At 3 inches in diameter and 7.5 inches in length, it suits a range of commercial and industrial piping configurations. Licensed plumbers and pipefitters typically install this adapter in hydronic, fire suppression, and process piping systems where transitioning from grooved to flanged connections is required.

This adapter is suited for applications where grooved piping infrastructure must tie into flanged valves, pumps, or equipment. It is commonly found in commercial mechanical rooms, industrial process lines, and fire protection systems. The 3-inch size fits standard 3-inch grooved pipe ends and pairs with a matching flange on the opposing connection point. Installation is typically performed by licensed pipefitters or plumbers working on medium to large diameter piping runs.

Key Features

• Transitions from grooved pipe end to flanged connection in a single fitting
• 3-inch pipe diameter accommodates standard medium-size piping runs
• 7.5-inch overall length provides clearance for bolt access on the flange face
• Designed for use in grooved mechanical piping systems per Gruvlok 7788 series specifications
• Suitable for commercial and industrial hydronic, fire suppression, and process piping

Compatibility

Designed as an OEM-style grooved end flange adapter for use in 3-inch grooved mechanical piping systems requiring a transition to a flanged connection.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes. Depressurize and drain the piping system fully before removing any existing fittings or installing this adapter. Verify flange bolt pattern and gasket seating surface alignment before torquing fasteners. Follow the applicable ANSI or ASME flange standard and the grooved coupling manufacturer guidelines for groove dimensions and coupling selection.
