Replacement of the seal kit for the coffee brewing unit (brewer) in Jura coffee machines helps eliminate Error No. 8, excessive noise, and coffee leakage into the coffee grounds container. Often, only one or both seals of the block piston are damaged. The kit includes Jura seal for block piston 0.357X3.55 (2 pcs.) and Jura silicone lubricant (5 g).
