Match the outer diameter (OD) to your fittings or bulkhead connectors. For example, 20mm OD (≈3/4") is typically used for small aquarium return lines, while 40–50mm OD (≈1-1/2"–2") suits larger pond pumps and sump systems. Always measure your existing fittings before ordering. The 500mm (≈19.7") length can be cut shorter on-site if needed.

Rigid PVC pipe generally handles working pressures of up to 100–150 PSI at room temperature, depending on wall thickness and diameter. For aquarium and pond gravity-fed or low-pressure pump systems, these tubes are generally more than adequate. Avoid use in high-pressure industrial applications without confirming the pressure rating with us first.

Yes. Rigid PVC is inherently resistant to moisture, algae, and mild chemicals, making it suitable for outdoor pond plumbing and water garden installations. For prolonged UV exposure, consider wrapping or shading the pipe, as extended direct sunlight can cause gradual surface fading over several years. In most pond and garden irrigation setups, this is not a practical concern.

This tube is sized by outer diameter (OD) and is generally compatible with metric PVC slip fittings, bulkhead fittings, and solvent-weld couplings of the matching OD. For threaded connections, use a threaded adapter. Always verify the fitting's socket inner diameter matches the pipe OD before purchasing. It is not sized to US Schedule 40 NPS standards.

Rigid PVC is widely used in aquarium plumbing and is generally considered fish-safe once fully cured and rinsed. It does not leach harmful chemicals into water under normal aquarium conditions. If using solvent cement to join sections, allow adequate cure time (typically 24 hours) and flush the system thoroughly before introducing fish.

That depends on your project layout. A single 500mm (≈19.7") section is typically enough for a short return line or overflow standpipe. For a full sump loop, pond filter circuit, or multi-tank manifold, ordering 2–4 pieces at once saves on shipping and ensures consistent color and wall thickness across your build.

Yes. Rigid PVC cuts cleanly with a PVC pipe cutter, hacksaw, or miter saw. Deburr the cut end with sandpaper or a deburring tool before joining to fittings to ensure a leak-free solvent-weld or push-fit connection. The smooth-bore interior makes it easy to achieve a clean, square cut.
