## Long description

Set of 2 original Tetra replacement valves compatible with Tetratec EX 400, EX 600 and EX 700 external aquarium filters. These replacement valves are designed to restore correct water flow and ensure reliable sealing in filter heads and connecting hoses. Supplied as a pair, the valves help prevent backflow and support consistent filtration performance after routine maintenance or part replacement.
Advantages
These original Tetra valves are manufactured to match the dimensions and tolerances of the corresponding Tetratec EX series components, ensuring a precise fit and reliable operation. Replacing worn or damaged valves restores proper one-way flow, reduces the risk of leaks and air ingress, and maintains stable water circulation in canister filter systems. The set of two allows simultaneous renewal of both inlet and outlet connections when required.

 Function: one-way/check valve to prevent backflow and maintain correct water flow
 Material: durable plastic and elastomer sealing elements suitable for aquarium use

How to use
Turn off and unplug the filter pump and close any external valves or hose clamps to stop water flow before beginning. Detach the filter head or hose connections according to the filter manual, remove the old valve(s) and inspect the surrounding sealing surfaces for debris or damage. Install each replacement valve in the correct orientation so the flow arrow or check direction matches the filter flow, ensuring a snug fit and intact seals. Reconnect hoses and fittings, reopen clamps or valves, then plug in and start the pump. Observe the system for leaks and verify consistent water flow and priming.
Usage recommendations
Inspect valves periodically during scheduled maintenance and replace at the first signs of wear, cracking or loss of sealing to prevent leakage and backflow. Use original replacement parts to preserve filter performance, and follow the filter manufacturer's instructions for safe handling and installation. When in doubt, check the filter manual for valve orientation and recommended service intervals.
