DAS double-acting piston seal

- Product description：The DAS double-acting piston seal in a robust five part assembly is designed specifically for one piece pistons in a wide range of medium duty applications.
The DAS double-acting piston seal in a robust five part assembly is designed specifically for one piece pistons in a wide range of medium duty applications. The seal is also suitable for two piece pistons.
Comprised of a nitrile rubber sealing element, two split support rings, and two split L-shaped bearings located either side of the seal, the well proven nitrile rubber sealing element is designed to be extremely wear resistant with multi-lips for efficient dynamic sealing with minimal low pressure friction and, when pressurized, will be protected from extrusion damage by the extending lips of the support rings.
The support ring is manufactured from a tough, flexible, wear resistant thermoplastic polyester elastomer (TPE) and scarf cut for assembly.
Both the L-shaped bearings and support rings are grooved to ensure that the fluid pressure properly energises the sealing element and to prevent the possibility of any pressure trapping within the seal assembly.
