Asc Engineered Solutions 390042588 Grooved Mpt Reducer 3x2.5 in

Product Description

The ASC Engineered Solutions 390042588 is a Gruvlok 7097 series eccentric reducer fitting designed to transition between grooved pipe ends and male pipe thread (MPT) connections. Sized at 3 inches by 2.5 inches and cast from ductile iron, this fitting handles reduction in grooved piping systems while maintaining a flat bottom alignment — a key requirement in systems where drainage or air elimination matters. At 5.60 pounds, it ships with a painted red exterior finish standard for Gruvlok-series components. Licensed plumbers and pipefitters install this fitting in commercial and industrial piping assemblies.

The 390042588 eccentric reducer fits grooved piping installations in commercial mechanical systems, including HVAC hydronic loops, fire protection piping, and industrial process lines. The eccentric geometry keeps one side of the pipe bore flat rather than centered, which supports proper drainage and prevents air pockets from forming at the transition point. This fitting is appropriate for above-ground and in-building piping runs where a grooved-to-threaded transition is required at a size reduction from 3 inches to 2.5 inches.

Key Features

• Eccentric reducer design maintains flat-bottom bore alignment for drainage and air management
• Grooved inlet end compatible with standard grooved coupling systems
• Male pipe thread (MPT) outlet for direct threaded connection
• Ductile iron construction for strength and durability in pressure piping systems
• Painted red factory finish for corrosion resistance and visual identification
• 3 inch x 2.5 inch size serves common commercial pipe reduction requirements

Compatibility

Designed as an OEM-style grooved fitting for use with standard grooved pipe coupling systems in 3 inch to 2.5 inch transition applications. Specific system compatibility should be verified against project piping specifications and applicable coupling manufacturer requirements.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes and the coupling manufacturer's assembly instructions. De-pressurize and drain the piping system fully before removing or installing any grooved fittings. The grooved end requires a compatible grooved coupling to complete the joint — do not substitute couplings rated for different pipe schedules or outside diameters. Verify thread engagement on the MPT connection using appropriate thread sealant or tape per local code requirements.
