Profitec Pro 800 "O"링 P1012.4

I needed a spare for when the old one finally gave out, and this O-ring is exactly the right profile and durometer for the group head. It seated perfectly during my last maintenance round and now I can sleep easier knowing I have a backup.

Finally found the correct O-ring for my machine's group head after trying a few generic ones. It seated perfectly and stopped a slow leak I'd been dealing with for weeks. A little pricey for a single rubber ring, but you get the exact fit.

It's the right size and fit for the Pro 800, but for a single rubber ring the price feels a bit steep. It does the job for routine maintenance though.
