Pig Tail Proof Coil For Sample Valve

  • The clamp-on dispensing coils have a lot of names; Sample Coil, Pig Tail, Proof Coil. 
  • If your beer is carbonated in a Unitank or Brite Tank, you can’t simply open up the sample valve or you’ll have a cup (or face) full of foam. The Pig Tail Proof Sample Coil must be used with a lever-style TC Sample Valve which is available separately.
  • The beer in the bright tank was fully carbonated, under pressure. A pigtail's long length of narrow-gauge stainless-steel created resistance to the beer flow along its length, at a rate almost equal to the pressure in the tank.If the brewer had simply opened the sample valve without coil, With no resistance to keep the carbonation dissolved, the beer would have spewed out as foam.
