Sealing Experts Introduce Revolutionary Material

CoorsTek, a long-standing authority on seals and hardface seal components for a variety of severe-service environments, introduces a completely new line of sealsPolyGlydeTM self-lubricating seals.

Industry-Leading Performance

PolyGlyde seals offer exceptionally low heat generation in high-friction and high-stress environments. These seals provide vastly superior performance over traditional carbon materials:

         Runs much cooler – even in dry-running situations

         Leak-tight, impervious material

         Greater durability

         Less wear debris – runs much cleaner

         Broader resistance to chemical attack

         Suitable for fluid and gas applications

         Lapping of seal face not necessary

         Exceptionally stable

Hands-on Service Professionals

Whether you need one or one hundred thousand seals, CoorsTek offers exceptionally fast lead times and provides expert assistance with material selection to match your severe-service application.
