Fumoto's snap-on type plastic elbow converts a straight nipple to 90 degrees L-shaped nipple for improved hose connection. In addition to the existing N-series Engine Oil Drain Valves, the L-shaped plastic elbow fitting instantly converts the straight nipple to 90 degree nipple, allowing it to be used in tight areas where the clearance might be a problem. The 90 degrees bend will prevent the connected hose from kinking to insure full flow of oil from the oil pan with a simple flip of the lever. The Engine Oil Drain Valve replaces the conventional drain plugs to simplify oil changes.
