S30 Keg Barrel Spare Parts S30 valve, for barrels and kegs The new S30 valve for your keg comes in high grade stainless steel. The S30 valve can be equipped with a small piercing pin if you want to use 8g CO2 bulbs (use the bulb holder below to screw these onto the valve). You can insert and remove the pin and easily switch between using S30 cylinders and 8g bulbs. For convenience, the valve comes in two versions - either pre-equipped with a piercing pin for 8g bulbs, or plain for use with S30 cylinders. Whichever version you get, it is as simple as removing/inserting the pin to change version. When you remove or insert the pin, you need to temporarily remove the small o-ring inside first (use a knife or small screwdriver - carefully). S30 bulb holder for 8g bulbs The S30 bulb holder comes with a Stainless Steel thread insert so it is practically impossible to wear it out, something that is often a problem with "compatible" products (make sure you get the stainless steel insert, or it won't last very long!). S30 Pin Conversion Pack If you have a plain S30 valve, simply buy a S30 conversion pack (pin + o-ring), put the pin in and you have a valve that works with 8g bulbs. Although it would be possible to just put the old o-ring back of course, we have included a new o-ring with the pack to make sure there is still a perfect seal. S30 cap for pressure barrels (kegs) The S30 cap comes complete with either of: S30 cap, plain; S30 stainless steel valve (for S30 cylinders); S30 pin version stainless steel valve (for 8g bulbs) This cap fits all barrels with a 4" opening and guarantees that your S30 system works smoothly. Make sure you have an S30 cap if you use your keg with S30 cylinders!
