Al Cass 341 2.0 fl. oz. Valve, Slide & Key Oil

Al Fast Cass Valve Oil has a unique formulation that’s capable of mind-bending speeds, ensuring that you'll be able to keep up with the band — no matter how fast the tempo gets!

It's excellent on valves, but also a great trombone slide oil and lubricates keys on other instruments too. This oil is so tough that it won’t separate in any weather conditions.
