CMA Small Steam Valve Knob
Officially called the “Knob Steam Tap Rio” by CMA, this friction-fit knob fits any Astoria or Wega steam valve stem of the correct diameter, a quick, inexpensive fix for a cracked, loose, or missing steam knob.
SPECIFICATIONS
- Diameter: 39 mm
COMPATIBILITY
- Fits: Astoria and Wega (CMA family) steam valves using a 39 mm knob
INSTALLATION
Simple DIY press-fit installation, no tools required.
PRO TIPS
- This knob is a friction fit onto the valve stem’s knurled shaft, with no set screw, if your old knob spins freely without opening the valve, it’s almost always the knob (not the stem) that needs replacing.
