Moen 1423, Tub and Shower Balancing Spool

Moen 1423 Balancing Spool for Moentrol Single-Handle Tub/Shower Valves

The Moen 1423 is a replacement balancing spool specifically engineered for use with Moentrol single-handle tub and shower valves. This component plays a critical role in pressure-balancing systems, maintaining a stable water temperature during pressure fluctuations in the supply lines.

Constructed for long-term durability, the 1423 balancing spool helps prevent sudden changes in water temperature by regulating hot and cold water pressure within the valve body. It is essential for maintaining consistent performance in Moentrol valves, particularly in residential and commercial installations where pressure changes can occur due to simultaneous fixture use.
