Original Anti-keystone Concept

 

  • Uncompressed, conventionally braided packing creates voids between the rings.

  • On compression, conventionally braided packing creates hardened pressure points that can cause excessive shaft/sleeve wear.

 

 

UNCOMPRESSED ANTI-KEYSTONE®I PACKING:

  • Becomes square-shaped on initial installation

  • Eleminates the need for extra compression thereby preventing excessive shaft/sleeve wear!
