EZ Oil Drain Valve EZ-106 30277 1.00 EZ Oil Drain Valve EZ-106

$ 23.95

The EZ Oil Drain Valve replaces the standard oil drain plug, making oil changes easier, saving valuable time and expenses. With just the push of a lever, you can easily change your engine oil without the mess! The EZ Oil Drain Valve is Constructed from corrosion-resistant forged brass, stainless steel, and a nickel-plated coating. Built to withstand extreme temperatures and harsh environmental factors such as salt, water, oil, chemicals... etc the EZ Oil Drain Valve is proven solid and will outlast your engine. With a complete length of only about 7/8" long, this valve only extends out a 1/2 more than the standard plug head from the oil pan. Will my EZ Oil Drain Valve open up on the road? No. The valve's effective locking system requires a double action mechanism to open it, this prevents any accidental openings. Unlike spring loaded gate valves, the heavy duty ball valve construction will withstand any engine vibration. In extreme conditions such as off-road, logging and agricultural applications (corn fields, brush areas..etc), you can add a "hose clip" around the body of the valve right above the lever (not included). This will provide additional safety and security. A typical hose clip can be purchased at any hardware store and will keep the level in the closed and locked position at all times. To keep things even cleaner during routine maintenance, the EZ Oil Drain Valve can be used with the optional Hose Ends (sold separately, see related items below). The Hose Ends easily screw into the valve body allowing you to attach a hose to the valve for convenience and cleanliness.
