Space-grade lubricants

The Castrol Braycote and Brayco ranges deliver ultimate performance in the harshest conditions - from the ocean floor to outer space.

Space grade lubricants

Mission-critical lubricants

The unique formulations of our lubricants deliver the ultimate performance in the most extreme vacuum environments - keeping advanced space technologies moving in conditions where failure is not an option. Wherever equipment is pushed to the extreme, there is a Brayco lubricant to help maximise its reliability.

Vacuum-environment products chosen by NASA

Designed to perform for extended periods in extreme conditions, Castrol Brayco oils and Braycote greases are renowned for reducing the risk of contamination and mechanical failure.
