This lets the hybrid gasket be used in applications where traditional graphite seals fail for, such as oil-filled pipes.
Gaskets are usually installed in opening sashes, to minimize draughts, and increase efficiency in energy use. However, they can be located on fixed windows. They are an essential component of any uPVC windows.
Hybrid gaskets can offer superior performance in several ways, including increased room temperature tightness and crush resistance. They are also more durable than graphite-only gaskets and can withstand heavy torque loads without degrading or blowing out.
