Simriz® 498 High-Temperature Chemical Resistant FFKM

Simriz® 498 is the ultimate FFKM material outperforming every other FFKM material on the market. It’s unique patented material structure provides an outstanding long-term performance in nearly every environment. No matter if it’s extreme temperatures up to 325°C (617°F) or harsh chemicals or even overheated steam and hot water. Simriz® 498 is the best O-Ring Made for any application.

Why Use SIMRIZ® 498 over every other FFKM product:

  • Superior Long-Term Performance in Extreme Temperatures
  • Broadest Chemical Resistance to the Largest Number of Harsh Chemicals and Environments (e.g. strong acids, strong bases)
  • Outstanding Performance Under Steam and Hot Water Conditions
  • Low compression set resulting in an increased product life time
  • Without equal. Patented cross-linking system provides superior performance beyond the limits of every other competitor FFKM product
  • Vertically integrated. Freudenberg-NOK Sealing Technologies is the only vertically integrated O-ring manufacturer in the world
  • Cost efficient. As the only vertically integrated O-Ring manufacturer down to the monomers Freudenberg-NOK Sealing Technologies is able to provide the most cost efficient FFKM O-rings

Simriz® 498 compound is formulated to far exceed the requirements of AMS7257, resisting high temperatures up to 325°C and a broad range of harsh chemical environments including strong inorganic and organic acids, steam and water, MIL-PRF-23699 HTS turbine lubricants after these lubricants start to degrade.

Simriz® 498 compound is formulated to far exceed the requirements of AMS7257, resisting high temperatures up to 325°c and a broad range of harsh chemical environments including:

  • Strong Inorganic and Organic Acids
  • Steam and Water
  • MIL-PRF-23699 HTS turbine lubricants after these lubricants start to degrade

Simriz® 498 resists splitting  at high squeeze under high temperatures where most competitive products rupture in these conditions.

Simriz® 498 Success Standards Include:

  • Extensive Testing Beyond The Requirements Of AMS7257
  • Out-Performs Competitive Materials In O-Ring Compressive Stress Relaxation Compared To All Competitive Materials Based On Customer Testing
  • Extensive Flight Testing In High Temperature Aerospace Applications

*This xross reference is intended to assist the user in determining the suitability of various elastomers in many different chemical environments. The ratings are based on a combination of published literature, laboratory tests, actual field experience, and informed judgments. As laboratory tests do not necessarily predict end-use performance, users of Freudenberg-NOK products must conduct their own evaluations to determine application suitability.
Additional information can be obtained from other publications such as Chemical Resistance Guide for Elastomers published by Compass Publications.
The information given in this cross reference guide is believed to be reliable, but no representation, guarantees or warranties of any kind are made to its accuracy or suitability for any purpose.
Unless otherwise agreed mutually in writing, any technical advice furnished by Seller to Purchaser before or after delivery of the Products is provided “as is” and on a gratuitous basis, without charge, and on the basis that it represents Seller’s good faith judgment, but without warranty of any kind, and is accepted at Purchaser’s sole risk.
