PTFE impregnation with corner braiding of abrasion-resistant aramid fibers creates this highly durable, non-contaminating, and long life packing. The strategic location of the resilient para-aramid fibers increases this braids abrasive resistance, while limiting shaft wear. Available as either spool stock or pre-cut rings, this product is useful in many different rotational applications.

  • Overview

Features and Benefits:

  • Combines the utilitiy of PTFE infused Synthapack yarns, with the toughness of para-aramid yarns to improved abrasion resistance and longer packing life
  • Abrasion resistance while limiting shaft and sleeve wear for lower operational costs
  • Surface lubricant for easier run-in
  • Versatile, multi-use packing means lower inventory stocking costs
  • Reduction in shaft and sleeve wear lowers operational costs
  • Versatile, multi-use packing means lower inventory stocking costs
