Better Brew S30 Pin Conversion Pack
The S30 conversion pack contains a high grade stainless steel pin for use with 8g CO2 bulbs, plus a small o-ring to fit inside the S30 valve. For conversion of an S30 valve, simply put the pin in and you have a 8g bulb version of the valve (use the S30 bulb holder for injecting the 8g bulbs). The S30 valve always contains a small o-ring inside.
