Markez ® O-Rings – High Temperature O-Rings & High Pressure O-Rings

Markez ® high performance perfluoroelastomer O-Rings (FFKM) offer unmatched value for demanding sealing applications. Produced from nearly identical ingredients as higher priced brands, Markez ® compounds are used for high temperature o-rings and high pressure o-rings and chemical resistant o-rings that deliver similar performance to major FFKM brands, with temperature resistance up to 625oF, at a significantly lower cost. Our proprietary processing allow us to supply seals under an inch in size more efficiently. Introduced exclusively to existing customers over 15 years ago, we now have the experience and capacity to offer Markez ® high temperature o-rings and high pressure o-rings to the world.

Markez ® compound number Z1028 is our most popular general purpose FFKM compound due to its relative low cost and broad range of chemical and temperature resistance up to 610 ºF (320ºC). Popular sizes are available in stock with rush manufacturing options available. Used as a cost effective alternative to Kalrez ® 6375, 4079 and 7075 in countless applications across various industries like Petro-Chem, Paint and Ink applications where resistance to harsh solvents is required. We welcome the opportunity to assist you in selecting the compound that provides the best value for your application. Our FFK O-Ring specialist engineers look forward to presenting the test data examples of why Markez ® offers the best value in the industry.

FFKM Dupont® Kalrez®, Markez®, Chemraz®, Perlast®, Isolast®, Parofluor®, Perfluorelastomer
Common Names:  Perfluoroelastomers, FFKM
Trade Names: Chemraz®, Kalrez®, Markez®, Isolast®, Parofluor® , Perlast®.

General Description: Perfluoroelastomer (FFKM) is a highly fluorinated elastomeric family of compounds that provide the most resistance to chemicals and high temperature than any other elastomer in the market.   FFKMs are considered the elastomeric equivalence to PTFE (Teflon) due to its excellent chemical and temperature resistance. Features:

• Excellent chemical resistance to most chemicals.
• The highest temperature resistant elastomeric material in the market.
• Can be molded into o-rings, X-rings and a wide variety of custom shapes.
• Available in many different compound and colors targeted for specific applications and markets
• Compounds available to meet FDA, USP Class VI and Explosive Decompression Resistance requirements.

Limitations:

• Molten alkali metals
• Dynamic applications

Temperature resistance:

• -46o to 327o C (-51o to 620o F).  Depends on compound and application.
