What this ring does
The Cimbali stuffing gland ring 18x135x4 mm is a sealing component designed to keep water and steam contained at a specific junction point inside the machine, preventing pressure loss and leaks during brewing operation.
Signs it needs replacing
Over time, a stuffing gland ring loses elasticity due to repeated exposure to heat and pressure cycles. This typically shows as dripping water, visible moisture around the sealed joint, or a noticeable drop in brewing pressure and temperature stability.
