A STEP FORWARD…
Aston Seals ® launches a new product.
The KHT, for its operational characteristics, is absolutely unique in the landscape of double-acting piston seals for medium-heavy applications where properties such as low friction, easy installation, compatibility to aggressive media, wide temperature capability, wear and extrusion resistance are required.
In hydraulic applications, a long service life is needed. To achieve this, the effectiveness of the sealing system is important.
Piston seals must operate for extended periods, under high pressure and friction.
Wear, extrusion resistance, compatibility to aggressive media and wide temperature range are vital to give long-term performance. While compact installation dimensions and easy installation are also essential.
Aston Seals developed the KHT to meet these criteria, provides the optimum sealing solution for industrial hydraulic applications.
The KHT piston seal
The KHT piston seal is composed of:
- an element in high resistance polymer on dynamic side which assures good sealing performance
- an O-Ring with low permanent deformation as energizing component on static side.
The compound
The dynamic element is a high resistance polymer specially developed by Aston Seals which 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. It provides better performance in low temperature environments keeping its good properties (“creep”, impact resistance, fatigue life) at high temperature.
Main advantages
- easy installation
- 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
