Developed for musicians seeking the highest quality lubricants, the three different viscosities of Superior Valve Oils meet the needs of a variety of piston valve clearances and provide greater stability in varying temperatures and environments.
- Light Oil is ideal for instruments with a tight piston clearance and music styles demanding fast valve action.
- Regular Oil is intended for instruments with regular piston clearance and players of all levels.
- Vintage Oil works best on instruments with a large piston clearance, such as low brass and vintage instruments.
