The SharkBite Tee Stop combines a SharkBite Push-to-Connect tee with a 1/4 inch Compression line and a quarter turn valve for easy on/off control of the supply line. This product is particularly useful for adding supply lines to fixtures such as dishwashers, humidifiers and ice makers. The Tee Stop also commonly serves as an alternative to a saddle valve. It can be used on Copper, PEX, CPVC or PE-RT tubing. The valve is easily rotated after assembly for easy installation, even in tight spaces.
