Beer CO2 Line Check Valve – 1/4" I.D.
The Beer CO2 Line Check Valve is recommended with every installation. Protect the beer gas blender from being filled with water when used in conjunction with bulk CO2 or a soda carbonator. Use with braided high pressure beer hose. The Pro-Line™ and Trumix® gas blender warranty only covers against water damage if a tee was installed.
