The Y-Strainer with 40 Mesh and Double Check Valve is a durable brass plumbing component designed to protect water systems by filtering debris while preventing backflow. Featuring a 40-mesh stainless steel screen, the Y-strainer effectively captures dirt, sand, and other particles that can damage valves, pumps, and appliances. The integrated double check valve provides added protection against reverse water flow, helping maintain system efficiency and water quality.
