Denis Wick DW4930 Advanced Formula Valve Oil with PTFE
PTFE is the most slippery substance on earth. Its unique properties transform ordinary valve oil into an extraordinary lubricant, the microscopic particles acting like minute ball-bearings.
Denis Wick sets a new standard in brass instrument lubrication with this 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. It 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 from the smallest piccolo trumpets to the largest tubas.
