Description

Add this inline check valve to any flared gas-in disconnect and protect your draft system! The check valve allows gas to flow out, but won't allow backflow of liquid into your gas system. Many manifolds and regulators already feature check valves, but this disconnect will keep liquid from ever entering your gas lines in the first place. Especially handy if you force carbonate your beer using the bev out dip tube!

Why we love it:  Because we've had beer shoot back into our gas line and that sucks. At some point you will have a keg that is pressurized more than the pressure in your gas system. This could be caused by different carbonation levels, a keg sitting at room temperature, etc. So for example if the pressure in your keg is at 20 psi and your regulator is set at 12 psi, when you connect your gas in quick-disconnect liquid shoots from the keg into the gas line. Eliminate that possibility with this ingenious fitting.

If you're looking for a ball lock disconnect with a built-in check valve, we highly recommend KEG729. However, the beauty of this inline check valve is that it can be used with any flared disconnect, including pin locks. If you don't want to part with your high-quality stainless steel disconnects, this inline check valve is for you!

I want some check valves on my kegs

Like the design

Because I spent too much money on regulators and I think a small investment to protect my equipment is a good idea.

Better than the post check valve
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.

Something I've needed for a while.
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!

Work perfectly
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.
