Alpha Hydraulic Assembly Seal Kit is used to give a seal to prevent the 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 their specific size and thickness. They enable the system to be closed to reduce the possibility of leakage.
