Silence Cap for SVEA 123 New Model, OPTIMUS 8R,99 RADIUS 46 Stove
Applicable Burners: Svea 123 New Model, Optimus 8R, Optimus 99, etc. Since burners directly preheat the fuel tank (e.g., Svea 123, Forevus, etc.), the heat from the tank can cause the filler port to harden quickly, so replace the fuel tank frequently.
