La San Marco 105 Steam/Water Valve Register Pin
Also called a reticulating plunger, this register pin is used across the La San Marco 105 line, including the multiboiler and “S” series machines.
COMPATIBILITY
- Fits: La San Marco 105, Serie New 105 multiboiler, New 105 S-E (steam and water units, Practical/Sprint 2/3/4 group “S” models)
- Replaces: La San Marco CCMMIN3320 (206949)
INSTALLATION
A valve-teardown-level swap best handled by a technician familiar with the 105’s steam/water valve assembly.
PRO TIPS
- This register pin (reticulating plunger) works alongside the valve body sold separately, if you’re rebuilding the valve, it’s worth inspecting the body’s seat at the same time, since a worn pin often means the mating seat has picked up wear too.
