Denis Wick Advanced Formula Valve Oil contains PTFE (Polytetrafluoroethylene) which is an extremely slippery substance. It is found in many everyday usages such as non-stick pans and 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 this innovative product. Developed in association with expert trumpet builder and repairer 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. 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.
