SharkBite Max flexible water heater connectors are the fastest and easiest way to connect your water heater to existing pipes in your home. A newly designed stainless steel collet retainer delivers additional strength and durability and provides a 200 psi pressure rating. SharkBite Max connectors do not require a PEX tube liner, and a re-engineered body allows you to insert the pipe using less force and greater ease. No soldering, clamps, unions, glue, or special tools required. After inserting to pipe, stainless steel teeth bite down and grip the pipe tightly while a specially formulated O-ring compresses around the pipe to create a watertight seal. The durable corrugated stainless-steel hose is a great option for areas that require hard piping but is still flexible enough to connect to water lines in tight spaces that don't line up. Available in additional lengths (12 in. to 24 in.) and with integrated ball valve shut off.
