Chesterton AWC808 95 Thermoplastic Technology Provides Durable Sealing

A.W. Chesterton introduces new AWC808 95 Shore A durometer thermoplastic polyurethane (AU) technology specifically designed to provide a high value, cost-effective sealing solution for standard fluid power applications in general and heavy industries. Due to its physical characteristics and chemical composition, the material is universally applicable for hydraulic and pneumatic cylinders.  AWC808 is available in North America, Europe, the Middle East, Africa and Asia Pacific.

Chesterton AWC808 has a durometer of 95 Shore A hardness, and high tensile strength improves material resistance against mechanical stress/impact, pressure load and high-energy radiation. The wear resistance and good friction properties offer improved reliability versus conventional rubber-based products, helping to extend cylinder mean time between repair (MTBR), according to the company. Its long-term elastic memory increases sealing preload which helps to ensure maximum performance even when exposed to low system pressure.
