A pioneer in the category, Spacefiller™ Quality Lubricants were developed to be the first ‘true’ synthetic lubricant for brass instruments. Many legacy lubricants are primarily based with petroleum distillates, have a strong odor, evaporate fairly quickly, and leave a residue that tends to ‘gunk’ up valves, rotors, and casings over time. Spacefiller™ Quality Lubricants are completely non-toxic, odorless and practically eliminate that problem.
