Piston Valve Oils---PRO-OIL HYBRID 141-A7

The oil that resulted from this unparalleled effort employs synthetic and non-synthetic components, hence the name PRO-OIL HYBRID was chosen. The current formula (141-A7) is the first in a generation of maximum performance piston valve oils. This colorless and odorless oil does not contain kerosene, silicone, or Teflon, and therefore will not cause a build up. It is sold in a protective clear package, and contains important information about cleaning the valves and valve casings prior to the first application of HYBRID. When it comes to professional quality hyper-tight piston valves, no other valve oil compares to PRO-OIL HYBRID (141-A7). PRO-OIL HYBRID is guaranteed to be the fastest, longest lasting piston valve oil in world or your money back. No other company can or does make that claim.

Professional quality horns have valves which are carefully honed to more perfectly match their valve casings. They are generally lapped by hand using a procedure which yields a much smaller gap between the piston surface and the valve casing. This, in turn, results in a tighter fitting valve. There are significant benefits to this approach, but some precision valves are so tight that, without a special valve oil, the valves tend to seize in the casing after a short playing time. In other words, very small changes are exaggerated when playing a professional quality horn. Musicians who make their living with their horn require an oil that not only is exceedingly fast and smooth, but also an oil that must not slow down during their performance. To meet the challenge, we had to solve the paradox of two competing properties: high speed and endurance. In 1991, we embarked on a new research program based on 20 years experience, laboratory testing of numerous candidate components, and intensive field testing by more than 50 world class musicians working in all kinds of playing conditions.
