75075305 AS568-257 DUPONT KALREZ 7090
- Exceptional thermal stability and compression set resistance | Outstanding seal force retention properties and response to temperature cycling effects | Excellent mechanical properties | Lower coefficient of thermal expansion (CTE) versus other Kalrez® parts thus minimizing the need to increase the free volume of the seal gland when upgrading from fluoroelastomers (FKM) to perfluoroelastomers (FFKM)
