The Iwata Eclipse Packing Head (or O-Ring) is used in 2 places on your Iwata Eclipse Airbrush body: between the head cap and the body and between the back handle and the body. If you have the Iwata Hi-Line Airbrush, you will find one between the body and the back handle. Your packing heads may need to be replaced on a regular basis to keep your airbrush functioning at its best.
