Al Cass “Fast” is a long-standing favourite for brass and woodwind players who want one reliable lubricant that simply works. It’s a petroleum-based, multi-purpose oil designed for smooth action on valves, slides, and instrument key mechanisms, and it’s formulated to resist gumming up or separating in changing weather conditions.

If you’re outfitting a student kit, stocking a band room, or you just want a dependable “grab-and-go” option for rehearsals and gigs, Al Cass is an easy choice.
