The ISTA Spring Check Valve’s stainless spring construction prevents water backflow in CO2 systems and air pumps.
How to use :

Type: spring check valve
Spring: stainless steel
Use: CO2 systems and air pumps
Connections: air tube fastening nodes at both ends
Suits CO2 systems and air pumps alike, on standard airline. The fastening nodes clamp the tube so it cannot burst off under pressure.
Fit it the right way round. Backwards it blocks the line; correctly, it is what stops tank water siphoning back down the airline into the pump or regulator when the power goes off — which is how air pumps flood and how tanks empty onto the floor.
One spring check valve with its air-tube fastening nodes. Airline is not included.
