Asc 390038503 Grooved X Mpt Swaged Nipple 3x2 in

Product Description

The ASC Engineered Solutions 390038503 is a Gruvlok 7078 series grooved x male pipe thread (MPT) swaged nipple designed for transitioning between grooved piping systems and threaded connections. This fitting accepts a grooved pipe end on one side and provides a male NPT threaded outlet on the other, allowing installers to bridge grooved mechanical joint systems with threaded equipment connections. The fitting is manufactured from ductile iron, offering the strength and durability required for demanding commercial and industrial piping applications. It measures 3 inches on the grooved end by 2 inches on the threaded end and weighs 5 pounds.

This swaged nipple is suited for use in commercial HVAC hydronic piping, fire protection, and industrial process piping where a grooved-to-threaded transition is required. The swaged design reduces the outlet from 3 inches to a 2-inch MPT connection in a single fitting, eliminating the need for an additional reducing coupling or bushing at the transition point. Plumbers, pipefitters, and mechanical contractors working on grooved mechanical piping systems will encounter this fitting in equipment room installations and riser transitions.

Key Features

• Grooved inlet end compatible with standard Gruvlok 7078 series grooved mechanical couplings
• Male pipe thread (MPT) outlet for direct connection to threaded valves, equipment, or fittings
• Swaged body transitions from 3 inches to 2 inches in a single piece
• Ductile iron construction for high-strength, pressure-rated performance
• Eliminates need for separate reducer and threaded nipple at grooved-to-thread transitions

Compatibility

Designed for use with Gruvlok 7078 series grooved mechanical coupling systems on 3-inch grooved pipe with a 2-inch MPT threaded outlet connection.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes and the manufacturer groove specifications. Depressurize and drain the system fully before removing any existing fittings or installing this nipple. Verify that the grooved pipe end meets the required groove dimensions for the coupling being used, and apply appropriate thread sealant to the MPT threads before making the threaded connection.
