CMP Hydroseal™ 25923-209-000 Clear 1-1/2" Socket 3-Way Diverter Valve with Unions, PVC. This Hydroseal™ Diverter Valve is designed for superior performance with professional features. Its dial wheel has 32 different stop settings for perfect control. Each stop can easily be located to always set the diverter to the same position. The Hydroseal™ "T" Gasket seal functions better than using simply an O-ring. The Teflon® coated silicon seal requires no lubrication for maintenance-free performance. The clear design makes it easy to observe flow and see if debris is lodged in the diverter. The extra visibility also means you can see exactly where the diverter is set.
