Compare the required internal and external diameter, length and connection type. Then select hose by the metre, a fixed length, connector or splitter to match the system.
Choose sera aquarium hose by internal and external diameter
sera aquarium hoses are available by the metre and in fixed lengths, with different internal and external diameters. This category also includes connectors and a hose splitter with tap. Hose, connector and splitter must match the intended water or air connection.
Measure the connection nozzle and compare the stated hose dimensions before ordering. The internal diameter determines whether the hose fits the connection, while the external diameter affects compatible clamps and fittings. Colour and length do not determine compatibility.
Route the hose without sharp bends, tension or unnecessary restriction. Secure pressurised or critical connections with suitable fittings and check them for leaks before operation. Replace hoses that have hardened, cracked or become permanently deformed.
