Rheem rtg20299ah Mixing Valve Outlet O-ring

Product Description

The RHEEM rtg20299ah is a replacement outlet O-ring designed for use in Rheem mixing valve assemblies. This small but critical sealing component prevents water leakage at the mixing valve outlet connection, maintaining system pressure and preventing water damage in the surrounding installation area. It is typically replaced during routine mixing valve service or whenever a leak is detected at the valve outlet. Plumbers and HVAC technicians servicing Rheem water heating equipment are the primary installers of this part.

This O-ring is suited for residential water heating applications where Rheem mixing valves are installed. Mixing valves are commonly found on tankless and storage water heaters to deliver tempered water at a safe, consistent outlet temperature. Replacing a worn or damaged outlet O-ring restores a proper seal and is a standard step during mixing valve disassembly, inspection, or replacement service calls.
