Seals
Rubber seals are made by forcing the uncured rubber through a die while it is under heat and pressure. This uncured rubber is then vulcanized, i.e. heated, to cause a chemical reaction which cures the rubber.
Rubber seals are a multi-purpose bit of kit that allow you to seal off two different surfaces or two opposite surfaces (interior, exterior). This prevents Water damage, water leakage, corrosion, weathering and also provides an air tight barrier which will prevent the loss of air/heat.
