Description
The Kalrez® LS390 perfluoroelastomer is a gasket for use in applications where FDA and Class VI compliance is required. This Tri-Clamp gasket is designed to address thermal, chemical resistance, compression set, and high static friction issues, which can cause intrusion and dead space in the process line. Which increases the risk of contamination and leakage
Description
Kalrez® LS390 has been designed to address these issues by offering high hardness properties, low stiction, excellent chemical resistance, and temperature resistance up to 220°C (428°F). These properties enable increased MTBR (Mean time Between Repair). Because of its unique grey color, LS390 seals are easy to identify for proper material selection and application.
