Rancilio Sight Glass O-ring - 12 x 18 x 3.2mm
Replacement o-ring seal for the boiler sight glass on Rancilio's older S and Z series machines. This is the current version Rancilio supplies; the original 12 x 20 mm o-ring is no longer available.
SPECIFICATIONS
- Dimensions: 12 x 18 x 3.2 mm
COMPATIBILITY
- Fits: Rancilio older S and Z series boiler sight glass
- Replaces: earlier 12 x 20 mm o-ring version (discontinued)
INSTALLATION
Simple DIY replacement - drain the boiler pressure first, then swap the o-ring at the sight glass fitting.
PRO TIPS
- A weeping or drippy sight glass is almost always this o-ring hardening from years of boiler heat cycling - replace it proactively during routine descaling rather than waiting for a leak.
