Ultra-Pure UPO-Classic Black Label Classic Valve Oil

Are your valves in need of some serious help? Look no further than Ultra-Pure’s Black Label Classic Valve Oil, the ultimate lubricant for old, well-worn rotary valves. Its formula is thicker than Ultra-Pure’s Professional Valve Oil, helping fill in the gaps between valves and their casings. Its thick and slick consistency allows valves to move without sticking. Horn players at Sweetwater note its fast-acting power — just a small drop under each valve cap will get your valves moving at top speeds! However, if you’re struggling with chronically sticky or frozen valves, we recommend trying a heavy-duty lubricant like Ultra-Pure’s Linkage Lever & Key Oil.
