## Long description

Replacement aquarium valves designed for use with Tetra EX500, EX700 and EX1000 Plus external filters. These spare/exchange valves allow controlled regulation of water flow and provide a sealed connection point that enables safe disconnection of the filter during routine maintenance. They are intended for freshwater aquarium systems where stable circulation and leak-free servicing are required.
Advantages
The valves offer precise flow control to adjust circulation rates without interrupting filtration. Their sealed coupling design reduces the risk of drips and leaks when disconnecting hoses for cleaning or component replacement. Manufactured to match the connection geometry and pressure characteristics of the corresponding external filters, they maintain system reliability and simplify maintenance procedures.
Suitable for
Replacement of worn or damaged inlet/outlet valves on Tetra EX500, EX700 and EX1000 Plus external filters
Routine filter maintenance and quick disconnection of hoses
Freshwater aquariums requiring controlled water flow and leak prevention during servicing
Key specifications
Compatibility: designed for specified external filter models in the Tetra EX Plus series
Function: adjustable flow control and sealed quick-disconnect coupling
Material characteristics: durable plastic components suitable for aquaria use
Connection type: hose-compatible coupling matched to original filter fittings
How to use
Install the replacement valve in place of the original inlet or outlet valve following the external filter manufacturer’s instructions. Ensure hoses are cut to appropriate length and pushed fully onto the coupling; secure any clamps if present. Use the valve control to set the desired flow rate and close the valve before disconnecting hoses to prevent water spillage. After maintenance, open the valve gradually and check for secure seals and correct flow.
Usage recommendations
Before installation, compare the spare valve to the original part to verify fit and orientation. Perform a leak check after connecting the valve and before leaving the system unattended. Replace valves showing visible wear, cracking or persistent leaks to maintain stable circulation and prevent water damage.
