The RECTORSEAL H-3402 FF-18 is a corrugated stainless steel flexible connector designed for water heater installations. The corrugated stainless steel construction allows for flexible routing between the water heater inlet or outlet and the supply piping, accommodating minor misalignment and reducing stress on threaded connections. With a 0.75 inch diameter and an 18 inch length, this connector suits standard residential water heater rough-in configurations. Plumbers and mechanical contractors install this type of fitting as a code-compliant, durable alternative to rigid pipe connections at the water heater stub-outs.
This connector is suited for residential and light commercial water heater hookups where a flexible, corrosion-resistant connection is required at the hot or cold water inlets. The 0.75 inch by 18 inch size matches common water heater port dimensions and typical clearance distances found in closet, alcove, and utility room installations. Its flexible design helps absorb slight movement or vibration from the water heater during normal operation.
Designed as an OEM-style replacement flexible connector for residential and light commercial water heater installations with 0.75 inch inlet and outlet connections.
Installation is performed by a licensed plumber in accordance with the International Plumbing Code and local authority requirements. Shut off the cold water supply and drain the water heater before disconnecting or replacing connectors. Do not over-tighten fittings on corrugated stainless steel connectors, as excessive force can damage the corrugations or sealing surfaces. Inspect threads on the water heater and supply line before installing to ensure clean, undamaged connections.
