CMA Flat-Sided Steam Valve Knob
This flat-sided steam valve knob fits any CMA-built machine, including Astoria and Wega models, and ships complete with its tension spring and securing spring already installed. New knobs seat very tightly on first installation, that’s expected, not a defect.
COMPATIBILITY
- Fits: Astoria, CMA and Wega steam/water valve shafts
- Works with: valve shaft tension spring (included)
INSTALLATION
DIY-friendly, though expect to apply firm, even pressure since the knob is a tight press-fit when new.
PRO TIPS
- A dab of food-safe silicone lubricant on the shaft makes seating a snug new knob considerably easier and helps prevent future seizing.
