EZ-A-201 EZ Oil Drain Vale Adapter (NPT3/4-14 x NPT 3/4-14) Thread Size

Some oil pans are designed with a recessed drain hole which may prevent the valve from being installed properly. If the valve can not be tightened all the way without hitting the oil pan wall, do not install the Drain Valve to your vehicle. Adapters are available for some models.
