A gasket is a mechanical seal designed to fill the space between two surfaces. Its purpose is to prevent leakage or seepage, both into and out of the joint between the two surfaces. For example, where two solid metal surfaces meet – like a join in a pipe. We use a gasket because the seal can never be perfect, therefore a gasket fills that gap and ensures that no liquid or gas can escape or enter the joint.
A Vital Part of Any Exhaust
Gaskets are a vital part of any exhaust and are generally made up of numerous sections. Vehicles especially, require an effective gasket otherwise, exhaust pipe fumes can escape into places they’re not wanted. For example, the passenger cabin or into the environment. Or, not having passed through the catalytic converter, meaning that the vehicle is considered unroadworthy.
Wide Variety of Gasket Material Available
Gaskets are made from a range of materials, with solid material gaskets commonly using sheet metal. Exhaust gaskets in particular, are regularly made of steel or copper, especially at the head gasket. The head gasket is the gasket which is used in the joint between the engine block and the cylinder head. Older technology tended to rely on composite materials of asbestos or graphite, but these were particularly prone to blow-outs.
If exhaust gaskets are left to degrade, gases can leak through and require a replacement. In more extreme circumstances, a gasket can blow – particularly if it is made of aluminium. This is because aluminium has a high thermal expansion rate. As a result, this can cause damage to the engine block. This can be very expensive to repair, so we advise regular service and care. Additionally, head gaskets should be fit by a professional, as they need to be tightened to a particular torque using a torque wrench. Subsequently, if this is done incorrectly it can result in complete head gasket failure.
