The FISHER MANUFACTURING 5000-0012 is a right-hand, 3/4-inch check valve stem kit designed for use in plumbing and fluid-control applications where a check valve assembly requires stem replacement or service. The kit provides the components needed to restore proper one-directional flow control in an existing check valve body, making it a practical field repair solution. Licensed plumbers and pipefitters install this type of kit as part of routine valve maintenance or after identifying stem wear or failure during inspection. At 0.5 pounds, the kit is compact and easy to handle on the job.
This stem kit is suited for repair and maintenance work on 3/4-inch right-hand check valve assemblies in residential and light commercial plumbing systems. It is typically installed in water supply lines, hot water systems, or other fluid-handling piping where backflow prevention is required and stem integrity must be maintained for reliable valve operation.
Designed as an OEM-style replacement stem kit for 3/4-inch right-hand check valve assemblies. Verify valve body model and hand orientation before ordering to confirm fitment.
Installation should be performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure completely before disassembling the check valve body. Follow local plumbing codes, including applicable IPC requirements, when servicing backflow-control components. Do not reuse damaged stem components or force mismatched parts into the valve body.
