AS568-147 Simriz 485 Broad Chemical Resistance (FFKM) O-Ring

SIMRIZ® 485 Chemical Resistant FFKM Material

Operating temperature: +20°F to +446°F (-7°C to +230°C)

Why Use SIMRIZ® 485 over every other competitor FFKM product:

• Broad chemical resistance in a large number of harsh chemical 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
• Demonstrated performance. Successfully used in many customer applications
• 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

TYPICAL APPLICATIONS:

• Pumps
• Valves
• Paint Spray Equipment
• Mechanical Seals
• Dispenser Systems
• Vacuum Components

Simriz® 485 performs well in a wide variety of harsh chemicals as well as under overheated steam and hot water conditions. Its outstanding performance combined with the cost efcient price structure makes Simriz® 485 the perfect match for nearly every application in the chemical process industry.
