The chemical name of PTFE is Polytetrafluoroethylene, and it is the most slippery substance on earth. It is found in many everyday usages such as non-stick pans, Gore-Tex rainwear and in dental floss. Its unique properties transform ordinary valve oil into an extraordinary lubricant, the microscopic particles acting as minute ball-bearings.
Denis Wick is pleased to set a new standard in brass instrument lubrication with innovative new product. Developed in association with trumpet expert Will Spencer, Denis Wick Advanced Formula Valve Oil is already acclaimed as a favourite by many leading brass players. It gives modern valves a very silky feel, is exceptionally long-lasting and remains unaffected by extreme weather conditions, so no more problems of slow, sticky valves in hot weather due to evaporation.
Its lack of residue makes it a great favourite amongst horn-players, who don’t want to be taking valves apart to clean out gunky residue.
Its ability to carry on lubricating between applications makes it the most useful oil for instruments where evaporation can be a problem, such as the tuba, euphonium, and instruments with Thayer valves.
The oil is light and fast, and works equally well in piston and rotary valves. Its special properties work in the smallest piccolo trumpets and the largest tubas.
