NOK Klüber BARRIERTA JFE 251V High Temperature Long-Life Fluorinated Grease
BARRIERTA JFE 251V is a high-performance fluorinated grease (PFPE grease) developed by Klüber Lubrication (NOK Klüber) as part of the BARRIERTA JFE series of high-temperature long-life lubricants. The series uses perfluoropolyether (PFPE) base oil with PTFE thickener, providing outstanding thermal and chemical stability. The product is designed for applications requiring reliable long-term lubrication under severe conditions. It has excellent resistance to oxidation, chemicals, solvents and fuels, while maintaining stable lubrication performance at elevated temperatures. BARRIERTA JFE 251V is suitable for high-temperature furnaces, drying equipment, packaging machinery, chemical plants and mechanical components involving rubber or plastic materials. Typical applications include bearings, sliding bearings, guides and seals.
