Fluidmaster b1h18 Water Heater Connector 18 in 3/4 Fip

Product Description

The FLUIDMASTER b1h18 is a braided stainless steel water heater connector designed to replace or upgrade an existing water heater supply line. It measures 18 inches in length and features 3/4 inch FIP x 3/4 inch FIP fittings on both ends. The construction uses a polymer core wrapped in braided stainless steel wire, which resists kinking and creasing even in tight installation spaces. Nickel-plated brass hex nuts provide a secure, easy-to-grip connection. Extra-long crimped stainless ferrules add durability at the connection points. This connector is lead free and meets code requirements for flexible water connectors. Plumbers and water heater installers use this part for both new installs and service replacements.

This connector is suited for residential and light commercial water heater installations where a flexible, code-compliant supply line is required. The 18-inch length accommodates standard water heater rough-in configurations and gives enough slack to work in confined utility spaces. The 3/4 inch FIP fittings are a common size for water heater inlet and outlet connections. The braided stainless exterior provides protection against abrasion and burst compared to unbraided polymer lines.

Installation Notes

Installation is typically performed by a licensed plumber. Shut off the water supply and drain pressure from the line before disconnecting the existing connector. Hand-tighten the FIP fittings first, then use a wrench to snug — do not overtighten brass fittings onto threaded ports. Verify there are no kinks in the connector after final positioning and check for leaks before returning the system to service.
