The 3/4-in SharkBite x 3/4-in FIP x 18-in SharkBite corrugated stainless steel water heater connector allows you to easily connect your hot and cold water supply lines to your water heater. After applying pipe thread tape to the FIP nipples on your water heater, thread the FIP end of the water heater connector onto the tank and tighten with channel locks. Then simply push the SharkBite push-fit end onto copper, PEX, or CPVC pipes and your water heater is connected. The corrugated stainless steel lines are available in different lengths from 12-in to 24-in and are also available in braided stainless steel. SharkBite water heater connectors will decrease the amount of time and effort needed to install a water heater in your home and are the fastest way to complete your project.
