Markez was first introduced exclusively to existing Marco Rubber customers more than 15 years ago and has been market tested for more than a decade. The performance characteristics of Markez make it a worthy Chemraz® or Kalrez® alternative and warrant the price point for this FFKM material. More cost-effective than the brands it replaces, the investment in Markez is recouped through its many strengths, including wide-ranging chemical resistance and long life span. This means less frequent seal changes and repairs, fewer failures, and an increase in uptime — a productivity boost in the most demanding application.

Because it is proprietary, Markez is an FFKM material that Marco Rubber can design into any sealing solution — including custom shapes:

O-Rings
Popular sizes are available in stock with rush manufacturing options available.
