Almost killed a Dist. valve with blow back. this solved the problem.

Worked perfectly didn’t jam up. The other less expensive brand I purchased got stuck shut within a week while these kept on trucking.

Works as it should. Easy to install no more back ups.

No more beer backing up into the CO2 gas line when the tank goes empty

I was tired of moving my 5 gal kegs and seeing beer in the CO2 line. I switched to check valves to eliminate the issue. However the post check valves seemed to have a leak. I thought I had defective post check valves and bought brand new ones which cause all the CO2 to empty from the keg and the CO2 tank. After switching to the inline check valve I have not had any keg or CO2 tank to empty overnight.

Very happy with this product. I force-carbonate my beers in Corney Kegs inside my kegerator. I have always had problems with beer in the gas lines when carbonating multiple kegs at once. This nifty little gizmo solves that problem and I wish I had it long ago. Easy to use without any tools to connect/disconnect. Highly recommended!

Ever have beer get into your gas line? I hate that. This keeps that from happening. Happy now.

Stops beer from back following out my co2 inlets if I forget to vent off keg pressure before putting a keg on tap at serving pressure if it was already at a higher pressure for carbonation. Also keeps lines clean if using a soda bottle with carbonation cap and shaking to force carb small samples. Over all saves on potential line cleaning on all CO2 lines.
