Asc Engineered Solutions 390039774 Grooved X Fpt Adapter 4 in

Product Description

The ASC Engineered Solutions 390039774 is a grooved-by-female-pipe-thread (FPT) adapter fitting designed to transition between grooved piping systems and standard female threaded connections. Manufactured from ductile iron, this 4-inch adapter provides a reliable mechanical connection point in fire protection, HVAC hydronic, and industrial piping installations. At 4.50 pounds, the fitting is sized for 4-inch pipe and follows the Gruvlok product line specifications. Licensed piping mechanics and pipefitters install this type of fitting where a grooved mechanical joint must interface with a threaded pipe branch or equipment port.

This fitting is suited for commercial and industrial applications where grooved piping infrastructure meets threaded equipment connections. Typical scenarios include connections to threaded valve bodies, pump ports, or flanged transitions in wet-pipe fire suppression systems, chilled water loops, and condenser water distribution systems. The ductile iron construction handles the pressure and temperature demands common in these mechanical system environments.

Key Features

• Grooved inlet connects directly to standard grooved mechanical couplings
• FPT outlet accepts standard male-threaded pipe or fittings
• Ductile iron construction for strength and durability in pressurized piping systems
• 4-inch nominal size for compatibility with 4-inch grooved pipe systems
• Part of the Gruvlok fitting line for consistent system-wide performance

Compatibility

Designed as an OEM-style grooved transition fitting for 4-inch grooved piping systems requiring a female threaded outlet connection.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable codes, including NFPA 13 for fire suppression applications or local mechanical codes for HVAC hydronic systems. Depressurize and drain the piping system fully before removing or installing any grooved or threaded fittings. Verify that the grooved pipe end meets the appropriate groove specification for the coupling being used, and apply appropriate thread sealant to the FPT connection per manufacturer and code guidance. Do not over-torque threaded connections into the FPT outlet, as ductile iron threads can be damaged by excessive force.
