28 × 2 mm food-grade silicone O-ring for sealing the Gicar flowmeter, reference 6.9.10.22. The silicone is approved to the FDA standard for drinking-water contact and is rated to 180 °C. A sound seal keeps the water count reliable and prevents seepage into the electrical connection.
It is the sealing O-ring for the Gicar flowmeter, reference 6.9.10.22, fitted in the water circuit of the machine. Confirm the seal you removed: 28 × 2 mm.
What size and material is it?
28 mm outer diameter with a 2 mm section, in food-grade silicone approved to the FDA standard for drinking-water contact, rated to 180 °C.
Why does the flowmeter seal matter?
The flowmeter counts the water volume passing through so that each shot is dosed consistently. If the seal lets water past, you get drips and the count can drift.
When should it be replaced?
Whenever the flowmeter is taken apart, and as soon as damp or scale shows around the joint. It is a very simple part that prevents an electrical fault from seepage.
