Rubber Fab Kalrez Tri Clamp gaskets are a sealing product for use in food, beverage and pharmaceutical processing applications where FDA and Class VI compliance is required. Kalrez gaskets are specially designed to address thermal and chemical resistance, compression set issues and high static friction, which can cause intrusion in the process line. Their design solves these issues by offering high hardness, low stiction and a high temperature resistance. These properties enable increased MTBR (Mean time Between Repair). Because of its unique grey color, LS390 gaskets are easy to identify for proper material selection and application.
