  • For 4mm internal diameter tubing.
  • Made of stainless steel.
  • Easy to install.
  • Attractive design.
 

Description

A check valve is used to prevent water back-flow or siphoning down the tubing when the pressure is turned off.  If water were to reach your electronic equipment such as your CO2 solenoid, or air pump it can cause it to flood and not operate, or risk electrical fire.  This simple item eliminates that possibility by not allowing air or water to flow in the opposite direction to which it is installed.

Instructions

  • Cut your CO2 tubing in the position you would like check valve.
  • Direction of flow is indicated by by arrow on the valve.
  • Push CO2 tubing onto corresponding inlet/outlet as far as you can.
  • Tip: Softening the tubing in freshly boiled water will make it easier to push the tubing onto the valve.

    Does exactly what it's supposed to- keeps that water from sneaking back down the tube when the CO2 is off. Does exactly what it's supposed to- keeps that water from sneaking back down the tube when the CO2 is off.

    No backflow at all. It’s way more stylish than those cheap plastic ones, and it fits snugly, ensuring a gas-tight seal. Arrived really fast too. No backflow at all. It’s way more stylish than those cheap plastic ones, and it fits snugly, ensuring a gas-tight seal. Arrived really fast too.
