The SharkBite Water Heater Connectors are used in residential and commercial applications to connect the hot and cold supply lines to the water heater and add the option to shut off water supply at your convenience. The connectors are EPDM knitted with braided stainless steel. They are available in 12 inch, 15 inch, 18 inch and 24 inch length. The SharkBite connection allows the installer to connect to copper, PEX and CPVC tubing eliminating the need for an additional transition fitting.
