Description
The Xylem-McDonnell & Miller 325600 150-14H is a pack of 25 head gaskets, designed to create a tight seal between the cylinder head and flange in hydronic heating equipment like boilers. These resilient gaskets prevent leaks and ensure proper operation by withstanding high temperatures between 400-800°F. Made for raised flange heads with 8 holes, each gasket measures 5 ½ inches in outer diameter and 3 ¼ inches in inner diameter. Replacing a worn-out head gasket can improve boiler efficiency and prevent costly leaks, extending the lifespan of your HVAC system.
