A123 economic double acting piston seal set
A123 double acting piston seal is designed to be used in light duty hydraulic and pneumatic cylinders, and is intended for piston applications only.
A123 is a set of specially formed 98 Shore PU ring and a 70 Shore NBR energizing O-ring. It offers very good and economic static and dynamic sealing performance, simple low-height groove design, easy installation, and is suitable for standard housings, even in low speed working conditions. A123 seals are commonly used in light duty cylinders due to their efficient price-performance ration, and in case of necessity, they can also be used in pneumatic applications as piston seals.
Available in a wide range of metric and imperial dimensions.
