This is an authentic OEM replacement part that has been sourced directly from Jenny. This petcock is also known as a drain valve, and it is commonly used on air compressors. It is located on the air tank of the compressor and it allows you to drain the air and moisture from your tank. While air is being pressurized by your compressor a layer of moisture can build-up in the tank, this condensation can lead to corrosion in the tank. By draining the air and moisture you will help extend the life of your compressor, and you can prevent the pressure in the tank from building up to unsafe levels. Before you are finished using your compressor, and before you store it you should drain the air. The valve will commonly need to be replaced because it has become corroded, rusted, leaky, or stripped down. This drain valve has sealant on the threads, which helps to ensure the connection is air tight. Before you begin replacing this part make sure you have disconnected the power to your compressor, and drain all of the air from the tank.
