Chesterton Introduces New Thermoplastic Sealing Material for Hydraulic, Pneumatic Cylinder and Press Applications
AWC808 Offers Cost-Effective, Durable Sealing For Light and Medium Duty Applications


GROVELAND, MA – December 5, 2017

A.W. Chesterton Company is pleased to announce the availability of its new AWC808 95 Shore A durometer thermoplastic polyurethane (AU) technology. This material was specifically designed to provide a high value, cost-effective sealing solution for standard fluid power applications in general and heavy industries. 

Thanks to its physical characteristic and chemical composition, this material is universally applicable, delivering optimum performance, reliability and productivity for hydraulic and pneumatic cylinders.  AWC808 will be 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 improve material resistance against mechanical stress/impact, pressure load and high-energy radiation. The excellent wear resistance and good friction properties offer improved reliability versus conventional rubber-based products, helping to extend cylinder mean time between repair (MTBR).

​AWC808 is a thermoplastic polymer ideal for use in light and medium duty hydraulic/pneumatic applications. Its long-term elastic memory increases sealing preload which helps to ensure maximum performance even when exposed to low system pressure.

Material Features:​

  • Designed for industry-standard applications in heavy industry: Metal Forming, Wood Based, Injection Molding, Tire, Hydropower
