Product description
- The Ista stainless steel check valves prevent backflow of water to CO2 equipment and air pumps.
- Please note these check valves are designed for use with high pressure such as CO2 systems so may not be suitable for standard air pumps.
- These check valves are very durable and last a lot longer than traditional plastic check valves. They will accept a standard air line connection (4mm internal 6mm external diameter).
- Ista specialise in planted aquarium equipment and supplies, so you can be sure that these check valves are one of the most advanced on the market and made to the highest possible quality.
