All Hetman Musical Instruments Lubricants offer superior lubricating qualities, are longer-lasting than other lubricants, and are completely compatible with conventional petroleum-based lubricants, thereby avoiding potential gumming problems. The viscosity of each lubricant is carefully formulated for its specific purpose and assures both fast, positive action and vital protection against wear and corrosion.

Light Tuning Slide Oil A light-viscosity synthetic lubricant designed for tighter fitting valve slides and for valve slides of linger length. Provides rapid slide action when making intonation adjustments. Protects against wear and corrosion. Brush cap applicator.

Medium Tuning Slide Oil Medium-bodied synthetic oil was developed for trumpet first and third valve slides. Maintains seal and smooth slide action when making intination adjustments. Brush cap applicator.

Heavy Tuning Slide Oil A heavier-viscosity synthetic lubricant designed for looser fitting and shorter length valve slides. Improves slide tube seal. Helps prevent binding of shorter slides when making intonation adjustments. Brush cap applicator.
