Leak-Proof Design: Built in one-piece construction to minimize weak points and prevent leaks during long-term use. Easy to Install: Designed for quick, hassle-free setup even in busy commercial kitchens. This wall mount installation kit is compatible with most wall-mounted commercial faucets that have G1/2 female inlets, ensuring a secure, tailored fit for stainless steel sinks. Each elbow adapter uses a combination of plastic washers and flexible rubber washers, working together to create a superior sealing performance and stable water , reducing maintenance and downtime. Simply connect the longer end of the elbow to the back of the wall mount faucet, then attach the shorter end to the water line. Secure the faucet against the stainless steel sink using the lock nuts and washers, and apply water tape on threads to further reduce leakage risk.
