La San Marco Lever Group Piston Gasket
Black rubber piston gasket that seals the piston bore in La San Marco lever groups. This is the primary seal responsible for holding brew pressure during the lever stroke, once it wears, you'll see brew water sneaking past the piston instead of building pressure through the puck.
SPECIFICATIONS
- Dimensions: 50 x 31 x 10 mm
COMPATIBILITY
- Fits: La San Marco lever group piston bore
- Replaces: SM_7
INSTALLATION
Requires removing the piston from the group, a job for an experienced technician familiar with lever groups.
PRO TIPS
- A worn piston gasket shows up as a lever pull that feels progressively softer or spongier and a shot that never quite pressurizes, even with fresh coffee and a good grind, if backflushing and a new group gasket don't fix a weak-pressure symptom, check this piston seal next.
