Oil Drain Valves

Cost-Effective Oil Drain Valves for the Aviation Industry in Garden City, MI

In 1995, we designed and developed a new 'push-and-twist to lock open' oil drain valve. It was a unique design that received a US patent. This series of oil valve now covers most aviation engines made. The oil valve will accept a 3/8“ hose to drain the hot oil into a proper container for disposal. The standout feature is that the valve stays in place and does not need to be removed during the oil draining process. This means that you only have to safety wire it once, not every time you change the oil.
