Coloured PVC Round Tube — Solvent Weld Pipe for Plumbing, Aquariums & DIY Builds
When a plain grey pipe just won't do — whether you're routing a visible aquarium return line, colour-coding a workshop plumbing run, or building a custom display frame — finding a coloured PVC pipe that actually fits standard metric fittings is harder than it should be. These solvent weld PVC round tubes are made for DIYers, aquarium hobbyists, and trade professionals who need both function and a finished look.
Each piece is a single length of rigid PVC round tube, available in seven colours (White, Grey, Blue, Orange, Red, Black, and Clear Blue) across nine outer diameter sizes from 20mm (≈3/4") to 110mm (≈4-3/8"), with wall thicknesses ranging from 2mm to 4.8mm depending on the size. Choose from three cut lengths: 100mm (≈3.9"), 200mm (≈7.9"), or 500mm (≈19.7"). Sold individually — select your colour, OD×thickness, and length using the variant options above.
Typical applications include aquarium and fish tank filtration pipework, residential and light commercial cold-water plumbing, hydroponics irrigation loops, cable management conduit runs, and structural framing for retail displays or workshop jigs — anywhere a solvent weld PVC pipe in a specific colour adds clarity or visual appeal to the installation.

Compatibility: Designed for standard metric solvent weld PVC fittings (elbows, tees, couplings, end caps) matched to the same OD. Not compatible with imperial push-fit or compression fittings without an adapter. Confirm your fitting socket size matches the OD you select.
✅ Key Features of These Coloured PVC Solvent Weld Pipes
-
🎨7 Colour Options — White, Grey, Blue, Orange, Red, Black, and Clear Blue allow colour-coded plumbing runs and visible aquarium pipework without painting or wrapping.
-
📐Wide Size Range — OD from 20mm (≈3/4") to 110mm (≈4-3/8") covers most residential plumbing, aquarium filtration, and light industrial applications in a single product line.
-
🔩Solvent Weld Ready — Smooth, consistent bore and outer surface ensures reliable adhesion with standard PVC cement for leak-free joints in cold-water plumbing and aquarium systems.
-
💧Moisture & Corrosion Resistant — Rigid PVC does not rust, rot, or corrode, making it a dependable choice for wet environments including fish tanks, hydroponics, and outdoor sheltered runs.
-
✂️Cut-to-Fit Lengths — Three pre-cut lengths (100mm, 200mm, 500mm) reduce waste and on-site cutting for common short-run connections, riser sections, and display frame segments.
-
⚖️Lightweight & Easy to Handle — PVC's low density makes these tubes straightforward to transport, position, and install without specialist lifting equipment, even for larger 90–110mm diameters.

❓ Frequently Asked Questions
How do I choose the right OD and length for my project?
Match the outer diameter (OD) to your fitting socket size — the socket ID should closely match the pipe OD for a solvent weld joint. For length, measure the gap between fittings and add at least 20mm (≈3/4") insertion depth per end. Available lengths are 100mm (≈3.9"), 200mm (≈7.9"), and 500mm (≈19.7"). For longer runs, multiple pieces can typically be solvent-welded end-to-end using a coupling.
What pressure rating does this PVC pipe handle?
Pressure capacity generally depends on OD and wall thickness — smaller diameters with proportionally thicker walls typically handle higher pressures. For structural or pressurised plumbing applications, please contact us to confirm the rating for your specific variant, and verify compliance with your local plumbing code.
Can this pipe be used outdoors or in wet environments?
PVC is inherently moisture-resistant and will not rust or corrode, making it generally suitable for outdoor use in sheltered or partially exposed installations. For prolonged direct UV exposure, applying a UV-protective paint or coating is recommended, as standard PVC can become brittle over time in direct sunlight.
What fittings are compatible with these pipes?
These tubes are designed for standard metric solvent weld PVC fittings — elbows, tees, couplings, reducers, and end caps — matched to the same OD. They are not designed for threaded BSP/NPT or compression fittings without an appropriate adapter. Always confirm the fitting socket ID matches your chosen pipe OD.
Are these pipes safe for aquarium and fish tank use?
PVC pipe is widely used in aquarium filtration and circulation systems. Once fully cured after solvent welding — typically 24–48 hours — the joint is generally considered inert and fish-safe. Always allow full cure time and flush the system thoroughly before introducing livestock or sensitive invertebrates.
How do I cut PVC pipe cleanly for a leak-free joint?
A dedicated PVC pipe cutter or a fine-tooth hacksaw produces clean, square cuts. After cutting, deburr the end with 120-grit sandpaper or a deburring tool to remove any burrs or swarf. A clean, square end is essential for full solvent weld contact and a leak-free joint. Wipe both surfaces with PVC cleaner/primer before applying cement.
Can I use these coloured pipes for decorative or display builds?
Yes — the seven colour options make these tubes well-suited for colour-coded systems, visible display runs, retail fixture frames, and creative DIY builds where aesthetics matter alongside function. Clear Blue in particular works well for visible aquarium return lines where water flow is part of the display.
