Measure the inner diameter of your existing fittings or the opening you need to connect to, then select the pipe OD that matches. As a general guide: 20mm (≈3/4") suits small aquarium return lines; 25mm (≈1") fits standard pond pumps; 32mm (≈1-1/4") and 40mm (≈1-1/2") handle higher flow rates; 50mm (≈2") is typically used for main supply runs or larger filtration systems.

PVC pipe is generally considered safe for freshwater aquarium plumbing once fully cured. It is non-toxic and does not leach harmful chemicals under normal operating conditions. We recommend flushing the pipe with clean water before use and allowing any solvent cement joints to cure fully per the cement manufacturer's instructions.

Standard PVC can degrade with prolonged direct UV exposure. For outdoor installations, it is generally recommended to paint the pipe with a UV-resistant coating or use it in shaded runs. For fully outdoor applications, CPVC or UV-stabilized pipe variants are typically a better long-term choice.

This pipe is designed for solvent-weld joining using standard PVC solvent cement and primer. It is compatible with metric PVC fittings sized to match the listed OD. Always verify fitting inner diameter against the pipe OD before purchasing fittings. Threaded connections require appropriate threaded PVC adapters.

Wall thickness is 2mm for the 20–40mm OD sizes and 2.4mm for the 50mm OD size. Pressure ratings depend on temperature and installation method; for low-pressure aquarium and water feature applications (typically under 30 PSI), this pipe is generally adequate. For high-pressure plumbing, please contact us to confirm suitability.

Yellow coloring provides instant visual identification in multi-pipe systems, making it easy to trace specific lines in aquariums, water features, or DIY fluid routing setups. It is especially useful when running multiple pipe runs side by side and needing to distinguish between supply, return, or drainage lines at a glance.

Yes. PVC pipe cuts cleanly with a standard pipe cutter, hacksaw, or miter saw. Always deburr the cut end with sandpaper or a deburring tool before joining to ensure a leak-free solvent-weld connection. The listed 500mm (≈19.7") length can be cut down to suit your specific installation requirements.
