Single-acting piston seals are simpler in design than double-acting piston seals and are more suitable for applications where pressure only needs to be maintained in one direction.

Our GSD is particularly suitable for use as a single-acting piston seal with excellent sealing capabilities.
Its design has a small moving surface contact area to reduce friction and is suitable for high-precision positioning requirements and oil-free lubrication applications.We also supply single acting rod seals.
