The 1/2 in. SharkBite Click Seal Faucet Connector is the easiest way to install a new Faucet Line. The valve is perfect for potable water and hydronic applications where a shut-off is needed. Just insert the pipe and the stainless steel teeth bite down and grip tight, while a specially formulated O-ring compresses to create a perfect seal. Disassembly is just as fast using the simple disconnect tool so fittings and valves can be easily changed and reused. They can even be rotated after assembly for easier installation in tight spaces. SharkBite Fittings are certified for potable water supply and hydronic heating applications. The "Click" Seal technology also means there is no need for tools, simply turn the Click Seal nut until it clicks and you have a secure seal.
