FN Lube and FN Lube Plus are purpose-designed O-ring lubricants developed to reduce installation friction, protect sealing elements, and support consistent performance across a wide range of industrial and maintenance applications. Developed in collaboration with Klüber Lubrication, part of the Freudenberg Group, both lubricants are engineered to ensure material compatibility when used together with Freudenberg-NOK Sealing Technologies sealing solutions.
