The CROWN INDUSTRIES CSC0612 is a stainless steel flexible water heater connector designed to link a water heater to supply and return plumbing lines. Constructed from stainless steel for corrosion resistance and durability, this connector measures 12 inches in length with 3/4-inch female iron pipe (FIP) threaded ends on both connections. It is used in residential and light commercial water heater installations where a flexible, corrosion-resistant connection is required between rigid supply piping and the water heater inlet or outlet ports. Licensed plumbers and mechanical contractors install this type of fitting as part of standard water heater service or replacement work.
This connector is suited for hot and cold water supply connections on residential tank-style water heaters. The 12-inch flexible length accommodates minor misalignment between the water heater port and the supply stub-out, reducing stress on the plumbing connections. The 3/4-inch FIP thread size is the standard connection size found on most residential water heater inlet and outlet ports, making this connector a common replacement or new-installation fitting for plumbing contractors.
Designed as an OEM-style replacement or new-installation connector for residential tank-style water heaters with standard 3/4-inch FIP inlet and outlet ports.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the cold water supply and drain the water heater before removing or installing any connectors. Apply thread sealant tape or pipe dope to all FIP threaded connections to ensure a leak-free seal. Do not over-bend the flexible connector beyond its rated flex range, and avoid kinking the connector body during installation.
