FKM Fluorocarbon O-rings and Seals Last Longer
FKM o-rings and seals can help you reduce your lifetime costs by preventing seal failures, extending maintenance intervals, handling more aggressive fluids and higher temperatures, increasing safety and meeting stringent environmental regulations.
Reduce Your Lifetime Costs
FKM fluorocarbon o-rings far outlast o-rings made from nitriles and other general-purpose elastomers. That means you can extend service intervals and stretch maintenance budgets. FKM fluorocarbon has excellent mechanical properties, resistance to extrusion, resistance to chemicals and heat, retention of elastic properties over time and excellent resistance to atmospheric oxidation, sunlight and ozone.
Cut Unscheduled Downtime
FKM fluorocarbon o-rings and seals are so reliable they will help protect against unscheduled downtime. If you offer warranties on your products, you can extend the warranty periods with confidence.
Increase Temperature Capability
In many applications, rubber parts are stressed by accidental temperature excursions as well as by increases in operating temperatures designed to increase production. In some situations, FKM fluorocarbon o-rings can serve continuously at 204°C with excursions to 315°C.
Resist Aggressive Fluids
FKM fluorocarbon o-rings perform well in a wide range of aggressive fluid environments. They can tolerate changes in fluids and have more versatility for broader application.
Comply With Tougher Regulations
Environmental regulations have raised the stakes for leaks, spills, and emissions. FKM fluorocarbon o-rings and seals help guard against these problems to improve manufacturing and automotive operations.
Since its introduction in the 1950's, FKM fluorocarbon o-rings have solved sealing and other problems in major industries:
uses of FKM fluorocarbon o-rings include bonded seals, radial lip seals, caulks,
coatings, vibration dampeners, expansion joints, gaskets, o-rings, piston
seals, custom shapes, and stock rod and sheets.
The compatibility of FKM fluorocarbon with some important chemical media is shown in the table below. The capabilities of other elastomers shown for comparison can be helpful when you are considering changing materials to increase reliability or accommodate more severe operating conditions.
FKM fluorocarbon also offers mechanical ruggedness so o-rings, seals and components resist damage during installation and use. Basic mechanical property data listed show that FKM fluorocarbon compares favorably with other elastomers in tensile strength, range of hardness and resistance to compression set.
FKM fluorocarbon retains sealing force to prevent leaks even after compression for long periods in severe environments. After 100 hours in air at 150°C, it retains more than 90% of its original sealing force, while o-rings and seals of fluorosilicone, polyacrylate and nitrile retain only 70, 58 and 40% respectively.
FKM fluorocarbon has excellent resistance to atmospheric oxidation, sunlight and ozone. After 20 years of exposure to direct sunlight, o-rings and seals of FKM fluorocarbon showed no traces of cracking. Also, FKM fluorocarbon did not crack after one year in an atmosphere containing 100 ppm ozone.
