The KS piston sealing set made of wear-resistant Ultrathan® has been developed specifically for sealing floating pistons in dual media piston-type accumulators. It consists of two U-rings with differences in terms of design and compound. The shape of the seals makes the KS piston sealing set ideally suited for reliable, low-friction separation of different pressure fluids (oil/gas). Other applications include industrial shock absorbers and hydro-pneumatic elements such as feed and braking units, pressure converters, pressure transducers and working cylinders.

• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Assembly on one-part piston is possible.
• High extrusion resistance.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the chemical process industry.
• Suitable compounds available for special requirements of the food processing industry.
• Dimensions according to ISO 5597.
• Installation in closed and undercut housings.
• Further dimensions of machined series with short lead times available.

Range of application:
For hydraulic piston accumulators. Other applications include industrial shock absorbers and hydro-pneumatic elements such as feed and braking units, pressure converters, pressure transducers and working cylinders.
