RMMR Valve Oil

RMMR Valve Oil is a petroleum brass valve oil. It is designed for smooth piston valve action on trumpets, baritones, euphoniums, tubas, and other piston-valve brass instruments.

This is a practical everyday oil for students, school programs, and brass players who need a dependable case-bag lubricant. As with any valve oil, it works best on clean valves and should not be mixed heavily with unknown oils already on the instrument.
