O-ring 14.5x3 (5 ps) De Dietrich 7665267

The O-ring 14.5x3 is a sealing ring used in various connections within heating systems to prevent fluid or gas leaks. As a small but vital part of boiler spare parts, it ensures tight seals in water or gas circuits, such as at pipe joints or valve connections. In burner spare parts, O-rings maintain pressure integrity and safety. Replacing worn O-rings during boiler maintenance and repair is a simple yet effective way to prevent leaks and system inefficiency.
