น้ำมันหล่อลื่นยามาฮ่า Valve Oil ทรัมเป็ต Regular
The Yamaha RVO Regular Superior Valve Oil is bases on a newly developed synthetic formula that is more consistent than mineral-based oil to provide superior performance in all playing environments. The RVO Regular Oil is made up of even-sized molecules to allow the oil to evaporate smoothly, guaranteeing a longer life with extremely responsive action. The Regular Superior Oil is designed for instruments with standard valve tolerances, such as student trumpets and is the same oil included with all Yamaha Student Series Instruments. The Yamaha RVO Regular Superior Valve Oil is available in a 1.28 ounce plastic bottle.
