The Ultra-Pure Light Bearing Oil is a new addition to the brand, with this particular oil being used on rotating bearings on both the top and bottom of rotary valves. Slightly thicker than Ultra-Pure Professional Valve Oil, this light bearing lubricant is brilliant for any piston valves that may be missing plating or are simply worn from use. The synthetic, non-toxic and odorless oil is long-lasting and easy to apply; if your bearings and valves are slightly worn or leaky, this key oil can be used by simply applying a few drops down the slide tubes. Use the light bearing oil to prevent stuck valves on instruments that haven't been used in some time – they will be back to prime playing quality with ease.
