O-ring d.17.96x2.62 (10 ps) De Dietrich 7656971

An O-ring with dimensions 17.96x2.62 mm is a versatile sealing element used in many boiler and burner applications to prevent leaks at joints and connections. This size is commonly found in gas valves, water pumps, and other components where a reliable seal is essential. Over time, O-rings can dry out, crack, or become compressed, leading to leaks that affect system performance. Replacing a worn O-ring is a simple and inexpensive fix that can resolve many common issues. Made from durable elastomer, this O-ring provides an effective seal against gas, water, and oil in heating equipment.
