PEEK Plastic Seal Rings

Seal rings made from high-performance PEEK Plastic material molded by Minnesota Rubber and Plastics handle thermal expansion forces, are suited for use in a wide range of high performance applications, and can easily replace components made from metal or other types of plastic.

• Provides long operating life with chemical resistance and retention of mechanical properties up to 570 F (300 C)    
• Replaces metal components in assembles requiring high-performance seals in vehicle transmissions
• During operation acts as rotating planetary carrier for helical shaped ring gears in transmission assemblies
• Seal joints can be added to a design to minimize leaks or facilitate required fluid pass through when various mechanisms are actuated in a system
• Custom joint configurations molded into ring seals provide new options to ensure optimal fluid control while facilitating assembly of components
• Offers lower cost and requires less assembly time
• Weighs 50% less than many metal components
• Highly resistant to thermal degradation as well as attack by both organic and aqueous environments
