Al Cass.
Fast — the original valve, slide, and key oil. Multi-purpose, odourless, temperature-stable, used by brass players the world over since 1962.
“Probably the No. 1
valve oil in the world.”
The atelier’s line, set above the door (and on the bottle): “Probably the No. 1 Valve Oil in the World.” The brief that follows: a multi-purpose, odourless lubricant for trumpets, cornets, and all brass instruments — “does not stick and does not dissolve” across temperature extremes.
Read the catalogue and the catalogue is the bottle: Fast, valve / slide / key, 2 oz with dropper tip. Released in 1962 and on the bench of working brass players ever since.

A working bottle
One formula.
Fast — valve, slide and key in one bottle. Multi-purpose, odourless, temperature-stable; doesn’t stick in the cold, doesn’t thin out under stage lights. 2 oz, dropper tip.
The catalogue is one product because the formula has held since 1962 — the brief at Al Cass has always been the lubricant that gets out of the way of the player.
