Simplify your plumbing projects with the SharkBite brass push-to-connect frost-free sillcock. Ideal for working in tight spaces, the frost-free sillcock features an integrated vacuum breaker to prevent backflow and a mounting flange to secure the valve. The outside faucet valve of this sillcock features an integrated 1/2 inch push-fit inlet and 3/4 inch garden hose outlet, and a shut-off can be found at the inlet of the sillcock to drain the water and provide protection for the valve when freezing. These brass sillcocks work well with PEX, CPVC, PE-RT, SDR-9 HDPE, and copper pipes. The SharkBite brass frost-free sillcock features a push-to-connect mechanism for a watertight union, and allows for quick and easy installation, with no tools, crimping, glue, or soldering required, and can be installed in wet lines. Approved for behind-the-wall applications with no access panels, these plumbing sillcocks are suitable for freeze, emergency repairs, and home improvement projects. All SharkBite valves, clips, joints, and adapters are manufactured and tested in the USA.
