The Fumoto SX-series is an engine oil drain valve, designed to help users quickly and easily change the engine oil.

It is comprised of two distinct but fully integrated parts: the through bolt and oil-flow control body. These features allow the valve to be positioned for more convenient and easy oil changes.

The SX-series valve allows installation without an adapter on some vehicles that may have previously required one. A larger body and quad channels allow for improved flow rates and faster oil changes in certain sizes.
