The hybrid gasket can be used in situations in which graphite seals won't be suitable, such as pipelines that are filled with oil.

Typically, these gaskets are fitted in sashes with openings to prevent draughts and enhance efficiency in energy use. However, they can also be found on fixed windows. As such, they are a key component of any uPVC window.

Hybrid gaskets offer superior performance on many levels, including increased room temperature tightness and crush resistance. They are also more durable than graphite-only gaskets and can withstand heavy torque loads without deteriorating or blowing out.

The hybrid material encapsulation improves the seal's performance when exposed extreme temperatures. The fluorocarbon coating on the base seal reduces lubrication movement, which is a concern when using traditional graphite gaskets.
