حلقة "O" Profitec Pro 800 P1012.4

Knew I'd kick myself if I didn't have a spare P1012.4 during a routine descale, so I grabbed this genuine replacement. It seated perfectly into the group head without any wrestling, and while it's a small part, it's the exact fit you want for peace of mind.

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.
