This is a single O-ring for a coffeemaker/espresso machine. It measures approximately 5/16-inches in outer diameter and has a 3/16-inch inner diameter. This O-ring attaches to the tube, which is connected to the upper boiler. It acts as a water-tight seal to prevent liquid from leaking between these two connected parts. Due to the high temperature and wet conditions, this rubber O-ring is subject to wear and may require replacement.
