Spacefiller Quality Lubricants were developed to be the first ‘true’ lubricant for brass instruments. The biggest problem with brass lubricants is they are based primarily with petroleum distillates, are toxic and evaporated fairly quickly leaving a slight residue. This product practically eliminates that problem. Spacefiller Quality Lubricants are totally non-toxic, containing no petroleum distillates.
In developing Spacefiller, it was known that over 80% of brass instruments have their valves, piston or rotor, machined…thus we developed Spacefiller Ultimate I. It’s viscosity is suited to the tolerance of machined valves.
