Alisyn Valve Slide Key Oil is a premium synthetic oil that offers performance advantages to professional musicians and serious amateurs. Alisyn Oil is clean, clear and stain resistant to offer exceptional rust, friction, and anti-wear protection. Alisyn oil remains on valve and slide surfaces and does not accumulate in the valve caps. The action on brass and woodwind instruments is smooth and quick and the oil remains serviceable at temperature ranges from -80 degrees F to 400 degrees F, making Alisyn Oil a top choice for musicians that play outside, especially for marching band performances in the summer and fall. Alisyn Valve Slide Key Oil is available in a 0.6 ounce plastic bottle.
