Tapco 51122-0070A Check Stops

Product Description

The TAPCO 51122-0070A is a check stop fitting used to control or block flow within a plumbing or HVAC system. Check stops are service valves that allow technicians to isolate a fixture or component without shutting down the entire supply line. This part is typically installed by licensed plumbers or HVAC mechanics during new construction, retrofit work, or fixture service. The 51122-0070A provides a reliable shutoff point at the point of use, making it a standard component in supply line assemblies.

Check stops of this type are commonly used in residential and light commercial plumbing applications. Typical install locations include under-sink supply lines, toilet supply connections, lavatory faucets, and similar fixture shutoff points. The part is suited for use wherever a local inline shutoff is required to service downstream components without interrupting the broader supply system.

Key Features

• Inline shutoff function allows fixture isolation without full system shutdown
• Designed for use at the point of connection between supply line and fixture
• Compact form factor suited for tight under-cabinet or wall-box installations
• Compatible with standard supply line assemblies in plumbing service work

Compatibility

Designed as an OEM-style replacement check stop for residential and light commercial plumbing fixture supply connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the main water supply and relieve line pressure before removing or installing any check stop. Use appropriate thread sealant or tape as required by the fitting type. Do not overtighten connections, as this can damage the valve seat or supply line threads.
