This Seal Kit is used in the Hydraulic Assembly 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 size and thickness.

They enable the system to be closed to reduce the possibility of leakage.
