Victaulic fd77425x14 Reducing Tee 4x4x2.5 in Ogs Grooved Sch 10S

Product Description

The VICTAULIC fd77425x14 is a Series 425 SS grooved reducing tee designed for piping systems that require a stainless steel fitting with reliable mechanical groove connections. Constructed from 304/304L stainless steel, this tee joins a 4-inch run to a 2-1/2-inch branch outlet using OGS grooved end connections. Rated for Schedule 10S wall thickness, it is suited for light-wall stainless pipe applications. Licensed plumbers, pipefitters, and mechanical contractors install this fitting in commercial and industrial piping systems where corrosion resistance and fast grooved assembly are required.

This reducing tee is used in commercial and industrial piping systems including fire protection, HVAC hydronic distribution, process piping, and potable or recirculated water systems where stainless steel is specified. The OGS grooved end style is designed to accept standard Victaulic-style mechanical couplings, allowing faster assembly compared to welded or flanged alternatives. It is appropriate for above-ground or concealed installations where Schedule 10S stainless pipe is used throughout the system.

Key Features

• 304/304L stainless steel construction provides corrosion resistance in wet and chemically active piping environments
• OGS grooved end style on all three outlets for mechanical coupling installation without welding
• 4 x 4 x 2-1/2 inch nominal size reduces branch outlet from a full-bore 4-inch run
• Rated for Schedule 10S wall thickness, compatible with light-wall stainless pipe
• Series 425 SS fits within the standard Victaulic grooved fitting product family

Compatibility

Designed for use with Schedule 10S stainless steel pipe in OGS grooved piping systems. Compatible with standard Victaulic-style grooved mechanical couplings rated for 4-inch and 2-1/2-inch pipe sizes.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes. Depressurize and drain the piping system completely before cutting into an existing line or removing any fittings. Verify that pipe ends are properly grooved to OGS specification and that coupling gaskets are seated correctly before tightening. Do not exceed the coupling and pipe system pressure ratings for the installed configuration.
