This lets the hybrid gasket be used in applications where traditional graphite seals are not suitable for, like oil-filled pipes.

The gaskets are usually placed in opening sashes, to minimize draughts, and increase energy efficiency. However, they can also be found on fixed windows. They are an essential component of any uPVC window.

Hybrid gaskets provide superior performance on many aspects, including improved room temperature tightness and crush resistance. They are also more durable and can handle more torque than graphite gaskets only.
