Kreul H311 mechanical key oil

Kreul H311 is a professional-grade lubricant engineered for high-precision woodwind keywork, packaged in a compact 8 ml dispenser. Developed in Tübingen, Germany, this formulation carries the legacy of the historic Hans Kreul workshop, known for manufacturing elite oboes and woodwind instruments.

The fluid is optimised for the high-tolerance screws, rods and tubes found on oboes, clarinets, bassoons and wooden recorders. Formulated for optimum stability, the oil resists gumming, oxidation and fluid migration under variable temperature conditions.

When applied it reduces friction, neutralises noise, and protects against moisture corrosion. It distributes evenly across moving parts, and for precise application the bottle is equipped with a needle-point applicator.
