Wedge gaskets are similar in design to bubble gaskets but with an elongated form at the top, instead of a flat edge.

This allows the hybrid gasket to be used in situations where traditional graphite seals are not suitable, such as oil-filled pipes.
Typically, these gaskets are placed in sashes that are open to reduce draughts and increase efficiency in energy use. However, they can be located on fixed windows. They are a key component of any uPVC window.
Hybrid gaskets can offer superior performance in several ways, including increased room temperature tightness and crush resistance. They are also more durable and can withstand more torque than graphite gaskets only.
The encapsulation of the hybrid material improves the seal's performance when it is exposed to extreme temperatures. The fluorocarbon coating that is placed on the core seal reduces lubrication movement, which can be a problem when using traditional graphite gaskets.
