The filter screen within the coupling is designed to capture any large particles that may pass through the pipes, preventing clogs or damage to downstream plumbing components. The coupling itself is made from durable materials such as PVC or ABS plastic, which are resistant to corrosion and can withstand exposure to a wide range of chemicals and fluids commonly found in plumbing systems. Overall, the McAlpine 1 1/4" In-Line Screened Filter Pipe Coupling is a reliable and effective plumbing component that can help prevent costly and inconvenient plumbing issues. ・ Available in ¾", 1", 1¼", 1½" and 2" sizes
