Reliance Worldwide 437012 Flexible Water Heater Connector 12in

Product Description

The RELIANCE WORLDWIDE 437012 is a corrugated flexible water heater connector designed for hot and cold water supply connections on residential and light commercial water heaters. Built from corrugated stainless steel with nickel-plated brass nuts and a nitrile rubber sealing washer, it handles temperatures from -40 to 180 degrees F and is rated to 125 psi. The 3/4 in FIP x 3/4 in FIP connections fit standard water heater inlet and outlet ports. This connector complies with no-lead laws, making it suitable for potable water installations. Licensed plumbers and experienced service techs are the typical installers.

This connector is suited for residential water heater installations where flexibility is needed to align supply lines with heater connections. The corrugated body allows for slight angular adjustment during installation, reducing stress on threaded fittings. At 12 inches in length, it fits most standard water heater rough-in configurations. It is used in both new installations and replacement service calls where the existing connector has corroded or failed.

Installation Notes

Installation is performed by licensed plumbers or qualified service technicians. Shut off the water supply and relieve line pressure before removing the old connector. Hand-tighten the FIP nuts first, then use a wrench to snug — avoid overtightening, which can damage the sealing washer or distort the corrugated body. Verify no leaks under full supply pressure before returning the system to service.
