The Pre 21 Omni Condenser Assembly is made entirely of titanium and uses High Temp O-Rings. It is compatible with body length midsections (NOT compatible with stem midsections). It is not compatible with the M Tip or stem midsections.
*Note Due to some Machine changes there are now 3 small dimples on the condenser to help ensure the MP is secure. They do not affect the function or the exterior look of the device.*
