Aston KHT Type

The piston seal type Aston Seals KHT is composed of:

• A dynamic seal element that, due to the special design, improves the pressure distribution and drastically reduces the friction. It is made of a special high resistance polymer that provides a winning combination for many parts and components: it gives the flexibility of rubbers, the strength of plastics, and the process-ability of thermoplastics. It increases the performance and service life in applications where properties such as abrasion resistance and tear strength are critical. Conical shaped notches allow the seal to energize without risk of extrusion of O-Ring.

• A standard size O-Ring with low permanent deformation as energizing component on the static side.

• Easy installation on a solid piston
• Returns to the size immediately after assembly
• Low friction and no tendency of stick-slip
• Simple groove design and space-saving construction
• Excellent wear-resistance
• High resistance against extrusion
• Extended service life
• Good temperature resistance
