Castrol Braycote™ 601 EF is a propellant-compatible, rust preventive grease formulated for use in aerospace, military, and critical industrial systems where protection against corrosion and compatibility with reactive chemicals are required. Manufactured with a perfluoropolyether (PFPE) base oil and a specialized thickener system, this grease offers excellent lubrication, long-term stability, and compatibility with liquid and gaseous oxygen (LOX/GOX).

Performance benefits include:

• Rust and corrosion inhibition, protecting metal components in highly reactive or humid environments

• Oxygen and propellant compatibility, making it safe for use in aerospace and missile applications

• Outstanding thermal and oxidative stability, resisting breakdown under high-temperature and oxidizing conditions

• Low volatility, ensuring clean, residue-free performance in vacuum and cleanroom environments

• Extended component life, minimizing wear on valves, seals, and fittings in critical systems

Packaged in a 1 lb jar, this size is ideal for maintenance teams, aerospace operations, and defense contractors needing bulk quantities for precision or assembly-line applications. Castrol Braycote 601 EF provides long-lasting corrosion protection, safe oxygen compatibility, and reliable performance under extreme service conditions.
