Watts 825203 4 Inch Flanged Cast Iron Wye Strainer

Product Description

The WATTS 825203 is a 4-inch flanged cast iron wye strainer designed to filter debris and particulates from pipeline systems in commercial and industrial plumbing and HVAC applications. The strainer features a 1-1/2-inch female pipe thread (FPT) blowdown port, allowing technicians to flush accumulated debris without fully removing the strainer body from the line. Built to 125-pound flange pressure class standards, the 825203 is a durable, heavy-duty unit weighing 64 pounds. Licensed plumbers and pipefitters install this fitting in water distribution, heating, and process piping systems where inline filtration is required to protect valves, pumps, and other equipment.

The 825203 is suited for 4-inch flanged piping installations in residential and commercial mechanical rooms, boiler rooms, and industrial process lines. The cast iron body handles the demands of high-flow systems where robust construction is necessary. The flanged end connections conform to standard 125-class drilling patterns, making this strainer compatible with existing flanged piping infrastructure. The integral FPT blowdown connection allows for routine maintenance without system shutdown, reducing service time in active piping systems.

Key Features

• 4-inch flanged connection rated to 125-pound flange class
• Cast iron body construction for durability in commercial and industrial service
• 1-1/2-inch FPT blowdown port for easy debris flushing without line removal
• Wye-style strainer geometry provides low pressure drop across the fitting
• Heavy-duty build at 64 pounds suits demanding mechanical and process piping applications

Compatibility

Designed as an OEM-style replacement or new-install wye strainer for 4-inch flanged piping systems operating within 125-pound class pressure ratings in commercial plumbing, hydronic heating, and industrial process applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the International Plumbing Code (IPC) and local mechanical codes. Shut down and depressurize the pipeline fully before installation or service. Orient the wye strainer with the screen pocket in the downward position where possible to allow gravity-assisted debris collection and effective blowdown. Use appropriate gaskets rated for the service pressure and temperature at the flanged connections.
