Al Cass Fast is the industry standard valve oil, and immensely popular worldwide. It was developed by Al Cass (1923–89), a mouthpiece manufacturer and consultant to the great names of the big band era.
Dizzy Gillespie himself requested and gave final approval of the oil. It also serves as an excellent slide and key oil.

Valve oil is essential for keeping all valved brass instruments in good playing condition. If you play regularly, we recommend every week removing each valve in turn, wiping it clean with a lint-free cloth, and applying a small amount (two or three drops) of valve oil before carefully refitting.
