PVC Round Tube Pipe | 20mm–110mm OD | Blue, Grey & White | 200mm Length

Measure the inner diameter of any fitting or connector you plan to use, then select a pipe whose outer diameter (OD) matches. For example, a 25mm OD pipe typically fits standard 25mm push-fit or solvent-weld fittings. When in doubt, go one size up — it's easier to reduce than to expand. If you're replacing an existing pipe, measure the OD of the old pipe directly with calipers.

Wall thickness scales with OD: the 20mm, 25mm, 32mm, and 40mm sizes are generally 2mm thick; 50mm is typically 2.4mm; 63mm is typically 3mm; 75mm is typically 3.6mm; 90mm is typically 4.3mm; and 110mm is typically 4.2mm. These values are consistent with standard metric PVC pipe schedules. See the variant options for confirmed specs on your chosen size.

PVC is generally resistant to moisture and many chemicals, making it suitable for outdoor and below-grade applications in most cases. However, prolonged UV exposure can cause surface chalking and brittleness over time. For long-term outdoor use, consider painting the pipe with a UV-blocking paint or wrapping it. For underground use, PVC is generally well-suited as long as soil conditions are not highly acidic or contaminated with solvents. Contact us to confirm suitability for your specific environment.

Pressure capacity depends on OD, wall thickness, temperature, and the fluid being carried. Smaller diameters with proportionally thicker walls generally handle higher pressures. As a general guide, standard metric PVC pipe in these sizes is typically rated for cold-water pressures in the range used for residential supply and irrigation. For pressure-rated applications, contact us to confirm the specific rating for your chosen size before installation.

These pipes are designed to work with standard metric PVC push-fit and solvent-weld fittings that match the listed outer diameter. Common compatible fitting types include couplings, elbows, tees, reducers, and end caps. Always verify the fitting's stated pipe OD compatibility before purchasing — metric PVC fittings are sized by the pipe OD they accept, so a "25mm fitting" accepts a 25mm OD pipe.

PVC pipe can typically be cut with a fine-tooth hacksaw, a dedicated pipe cutter, or a miter saw with a fine-tooth blade. Always deburr and chamfer the cut end before joining to ensure a clean, leak-free fit. For permanent connections, use PVC solvent cement (primer + cement) following the manufacturer's instructions. For removable connections, use push-fit or compression fittings rated for the pipe's OD. Allow solvent-welded joints to cure fully before pressurizing.

No — Blue, Grey, and White variants are made from the same rigid PVC compound and offer equivalent mechanical and chemical properties. Color is primarily used for system identification: grey is commonly used in drainage and waste systems, blue is often used for cold water supply lines, and white is popular for visible or decorative runs. Choose the color that matches your system's convention or aesthetic.

Standard rigid PVC is generally not recommended for continuous hot water applications. PVC typically begins to soften at temperatures above approximately 60°C (140°F), which can compromise structural integrity under pressure. For hot water lines, CPVC or other heat-rated materials are generally more appropriate. These pipes are best suited for cold water, drainage, irrigation, and conduit use.
