D28 M11 Ceramic Ring is the ceramic ring that seats the nozzle and isolates the sensor circuit. Outside diameter 28 mm, nozzle thread M11. Height was not stated on our spec sheet. A cracked ring throws the height sensor off and ruins the pierce. Replace it with the nozzle, not after the cut goes bad. Compatible consumable, not an OEM part. Pairs with D28 nozzles on the M11 ceramic interface.
When to use
Ceramic ring: Replace when it cracks or chips, or after a head crash. Match Ø and nozzle thread.
