Castrol Braycote™ 631 RP is a rust-inhibited, oxygen-compatible grease formulated for use in aerospace, military, and critical industrial applications where both lubrication and oxygen system compatibility are required. Developed with a perfluoropolyether (PFPE) base oil and a specialized thickener system, it provides excellent stability in oxidizing environments, including exposure to pure oxygen, liquid oxygen (LOX), and other reactive chemicals.

Performance highlights:

• Oxygen compatibility, making it suitable for aerospace and life-support equipment

• Rust and corrosion protection, extending the life of components in humid or reactive environments

• Excellent thermal and oxidative stability, resisting breakdown under extreme conditions

• Low volatility, ensuring clean performance in vacuum and controlled environments

• Long-lasting lubrication, reducing wear on valves, seals, and fittings in oxygen service systems

Packaged in a 2 oz syringe, this format is ideal for precision applications, cleanroom use, aerospace maintenance, and laboratory environments requiring controlled, minimal dispensing of lubricant. Castrol Braycote 631 RP ensures safe, reliable lubrication and corrosion protection in the most demanding oxygen system environments.
