Copper-Flex 18 in Water Heater Connector

Copper-Flex water heater connectors facilitate the attachment of water heaters and related plumbing devices to main supply lines in exposed locations. These connectors feature a patented internal dielectric sleeve that isolates dissimilar metals within the waterway to inhibit galvanic corrosion, which removes the requirement for a separate dielectric union during installation. The corrugated hose construction requires minimal torque to achieve a seal against the included pliable rubber washers, even when connecting to rough nipple surfaces. Extended connector nuts provide increased thread-to-thread contact to ensure a secure, leak-resistant connection for residential plumbing systems.
