SharkBite Max push-to-connect stop valves are the fastest and easiest way to connect to PEX, copper, CPVC, or PE-RT stub-outs, which control and shut off water flow to fixtures or appliances. This newly designed fitting features a stainless-steel collet retainer which delivers additional strength and durability. SharkBite Max fittings and valves don’t require a PEX tube liner and a re-engineered body allows you to insert the pipe using less force and greater ease. The single lever quarter turn handle allows for quick control over water flow, especially in tight spaces. No soldering, clamps, unions, glue, or special tools required. After inserting the pipe, stainless steel teeth bite down and grip the pipe tightly while a specially formulated O-ring compresses around the pipe to create a watertight seal. The valve can be rotated after installation for quick adjustments, and removing the valve is just as fast with a disconnect tool, allowing them to be changed or reused. (SharkBite push-to-connect fittings are the fastest when compared to other conventual plumbing methods. All other comparisons relate to first generation SharkBite push-to-connect products.)
