Hetman? Musical Instrument Lubricants achieve the optimum balance between quick action and protection of vital components. Hetman? lubricants are formulated in special viscosity grades that meet the specific requirements of the artist, and best suit the individual character of the artist's instrument. Performers are afforded the feel and confidence of a smooth, consistent action, while the longevity of their treasured instrument is prolonged by the unique formulation of each lubricant.

#4 - A ligher viscosity synthetic lubricant formulated for tighter-fitting valve slides and for valve slides of longer length (e.g. 3rd valve slides.) Provides rapid slide action when making intonation adjustments. Protects against corrosion and wear.

#5 - Original (Tuning Slide Oil) formula. A medium viscosity synthetic lubricant for first and third valve slides. Maintains seal and smooth slide action when making intonation adjustments. Protects against corrosion and wear.

#6 - A heavier-viscosity synthetic libricant for looser-fitting valve slides and for valve slides of shorts length (e.g. 1st valve slides.) Improves slide tube seal. Prevents binding when making intonation adjustments. Protects against corrosion and wear.
