The GSF is a typical single-acting, o-ring energized, low-friction piston seal especially useful where smooth movement and location accuracy is required. The GSF design is based on the very successful GSJ (DEF Code)rod-seal design which has been proven in the market to be an excellent seal. High-performance materials, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and high-speed capabilities.
This seal is available in a variety of DEF’s high-performance materials to suit a wide range of demanding applications.
The GSF’s design eliminates the potential for stick-slip and its very low running friction makes it ideal for high-speed applications. In particular, this seal is well-suited for use in piston accumulators in conjunction with other DEF piston seals.
Here is an example of GSF seal below:
