U3523LF : SharkBite 1/4" x 3/8" Compression Stop Valve Connector, Push On

Sharkbite 1/4" (3/8" OD) X 3/8" Compression Stop Valve Connector. Converts 3/8" compression stop to SharkBite®

The SharkBite® Connection System uses an advanced push-fit design that works in two stages. When the tube is inserted into the fitting, in the first stage, it passes through a release collar and then through a stainless steel grab ring. The grab ring has teeth that grip onto the tube. At the second stage the tube is pushed through an O-ring protector which aligns the tube. The specially formulated O-ring is then compressed between the wall of the fitting and the tube before the end of the tube reaches the tube stop. Only when the tube has passed through the O-ring and reached the tube stop, is a secure joint created. The SharkBite® fittings have an integral Tube Support Insert that is effective in supporting PEX tubing to ensure the O-ring seals correctly on the outside of the PEX tubing. The Tube Support Insert is not required when using CPVC and copper tubing; however it is not necessary to remove the insert when using these materials.
