Main Application

Massa-CF93 is recommended for static and dynamic application seals, mostly used for U-seals, wiper seals and packings in standard hydraulic systems. Due to its outstanding hydrolysis resistance it can be used in the most common hydraulic fluids and oil in water emulsions. Additionally, it is a recommended material for offshore applications.
