The FISCHER brand Glass CO2 Check Valve is a high quality , modern looking glass CO2 check valve. A must have for any tank with CO2 injection, a check valve prevents water from your aquarium from siphoning back into fragile and expensive CO2 equipment such as regulators and solenoids. Mountable both inside and outside the tank, this is a modern, small and unobtrusive check valve. A wise investment to protect your equipment from damage - at such an affordable price, there is no reason not to get one.
Hand crafted in the instantly recognisable 'typical' check valve shape, this clear glass check valve is a tried and tested design. Each check is hand made and unique - varying ever so slightly in shape, length and appearance, helping to achieve a natural looking planted aquarium.
Using a check valve couldn't be simpler, simply mount inline from your regulator to your diffuser, ensuring that the narrower end is facing down. If you are using other accessories such as bubble counters, then insure that the check valve is the last accessory before the solenoid/regulator.
Compatible with DIY yeast and pressurised CO2 systems.
High quality, hand crafted glass ensures every piece is unique and original.
Can be mounted both inside and outside the aquarium.
