Ista Stainless Check Valve for Co2, Silver

I didn't want to skimp on a check valve to protect my expensive regulator this seems to fit the bill Nicely fits snug with the black CO2 hose and does not appear to restrict the outflow it is just one of those things you hope to never have to test but it is nice to have the peace of mind when you have the best installed

Works well. was a little nervous buying this check valve since I know nothing of the brand. But directions are simple and it does prevent back siphon of water into my solenoid.

I dislike the fact this is my second defective one. Product quality is non existent

Ordered 2 and both were defective.

Great value for the money paid m, have sadly had to order from another seller at a higher price as they have none in stock but what they sent me was brilliant, worth it for a Co2 system just to be safe

Funktioniert einwandfrei, schützt super die co2 anlage. Würde ich immer wieder kaufen.

Using one of these for more than 3 months without any issue so far. Ordered another one recently and is working good as well. Looks sturdier than the plastic ones and has better connectors to avoid leakage.

Nice slim line non return valve.Does the job fine.

Bereits nach nur 4 Monaten musste ich heute feststellen, dass das Rückschlagventil anfängt zu rosten, und kein Wasser mehr zurück hält. Der Schlauch unterhalb des Ventils war heute Morgen komplett mit Wasser gefüllt.Ich bin enttäuscht!
