A pair of safety rings & a pair of matching seals. Compatible with all 9Barista machines.
The safety ring requires two seals when installed, so reuse the seals when installing the second safety ring.
The safety ring is a fail-safe device which will safely depressurise the machine if it’s overheated. You’ll know you need to replace the safety ring if you notice water leaking from a small hole on the side of the ring.
Instructions on how to fit the replacement safety ring can be found here.
