UNS Advanced Check Valve
The UNS Advanced Check Valve acts as a one-way firewall for your CO2 system or air pump. When equipment is placed below the water line, it lets gas flow into the aquarium effortlessly but slams shut the second backflow begins, preventing water from siphoning back into your solenoid, needle valve, or air pump motor. Features advanced one-way sealing mechanics, tool-free push-in fittings, and heavy-duty solid construction that withstands pressurized systems. Fits standard 4/6mm airline or CO2-resistant tubing.
