O-ring 27x3.5 epdm De Dietrich 7611472

An O-ring with dimensions 27 mm inner diameter and 3.5 mm cross-section, made from EPDM rubber, is a sealing element resistant to heat, ozone, and aging. In boiler and burner systems, it is commonly used to seal flanges, valves, or pump connections, preventing leaks of water, gas, or oil. EPDM's excellent weather resistance makes it suitable for outdoor or high-humidity environments. During maintenance, replacing deteriorated O-rings is a cost-effective way to stop leaks and restore system pressure. This versatile seal ensures tight joints in heating equipment, contributing to efficiency and safety.
