Rancilio Boiler Drain Screw, Old S-Series & Classe 10

Rancilio calls this the "GRUB INOX M12X14" (part #37091214), a threaded drain screw found in the old S-Series and early Classe 10 boilers. Rancilio has since replaced this design with a tube-and-expansion-valve assembly, so this is now an out-of-production item with limited remaining stock.

COMPATIBILITY

  • Fits: Old Rancilio S-Series and old Classe 10 boilers
  • Replaces: Rancilio 37091214

INSTALLATION

Simple hand-tool swap during boiler service, best done with the boiler drained and cooled.

PRO TIPS

  • Since this design has been superseded by a tube-and-expansion-valve setup, this screw is a like-for-like replacement only, it won't upgrade your boiler to the newer drain configuration.
