Alpha Valves and Unions Seal Kit helps to prevent loss of air, gas and water in most central heating systems. Many of the O-rings, gaskets, seals and washers are specific to a specific location within the boiler and are rarely interchangeable due to differences in size and thickness. They allow the system to be closed to reduce the possibility of leakage.
