CMA Sight Glass Gasket

Sealing gasket for the boiler sight glass (water level glass) on CMA-built espresso machines and the many brands that share this boiler design.

SPECIFICATIONS

  • Outside diameter: 16 mm
  • Inside diameter: 10 mm
  • Height: 8 mm
  • For use with 11 mm sight glasses only

COMPATIBILITY

  • Fits: Astoria CMA, BFC, Grimac, Lavazza, Orchestrale, Rio, Royal, Victoria Arduino, and Wega machines using an 11 mm sight glass

INSTALLATION

Simple DIY replacement, always replace both gaskets (top and bottom) when installing a new sight glass.

PRO TIPS

  • Confirm your glass diameter is 11 mm before ordering, this gasket won't seal properly on other glass sizes, and a leaking sight glass gasket is one of the most common causes of a slow drip under the boiler.
  • Snug the retaining nut down evenly and avoid overtightening, over-compressing this gasket can crack the glass tube.
