The Advanced Check Valve by Ultum Nature Systems is extremely durable and designed to handle high pressure while preventing the backflow of aquarium water into essential aquarium equipment. Backflowing water can cause permanent damage to air pumps and CO2 regulators.
The Advanced Check Valve is simple to install and easy to work with, preventing stuck tubing and eliminating any need to cut for removal. The Advanced Check Valve is ideal for longterm use and is a cost-effective option when choosing aquarium equipment. Suitable for use with planted aquarium CO2 equipment and aquarium air pumps.
