Aston SHTB Type

The Aston Seals SHTB is the optimal solution for industrial hydraulic applications. It can be used in the same housing normally destined to PTFE seal of which has similar technical and dimensional characteristics but, compared to it, better sealing capabilities, greater ease of installation and a lower cost.

The SHTB, composed of a high resistance polymer element on the dynamic side and an O-Ring as energizing component on the static side.

• Good sealing performance
• Low cost compared to the corresponding PTFE seal
• Easy installation
• Low friction and no tendency of stick-slip
• Returns to the size immediately after assembly
• Simple groove design and space-saving construction
• Excellent wear-resistance
• High resistance against extrusion
• Extended service life
• Good temperature resistance
