FR44/70 - High performance
This green coloured fluorocarbon (FKM) based synthetic elastomer is compounded by James Walker to exhibit low compression set characteristics. With a nominal hardness of 70 IRHD, it proves an excellent grade for O-rings that work across a wide temperature range in media such as petroleum fluids and mineral-based hydraulic fluids, as well as many solvents.
It meets a number of regularly used specifications, where its distinctive green colour proves a valuable aid to easy identification. Working temperature range is -20°C (-4°F) to +200°C (+392°F).
