ID 20-200mm PVC Water Supply Pipe Wall Mount Floor Flange Fittings Solvent Weld

Choose the Integrated Body when you are installing new pipework and the pipe end is free — you slide the flange onto the pipe before cementing the final joint. Choose the Split Body for retrofit or repair situations where the pipe is already fixed in place and cannot be threaded through a one-piece flange. The split body clamps around the pipe and is then secured to the wall or floor surface.

The size listed (e.g., 20 mm, 50 mm) refers to the pipe inner diameter (ID). Measure the internal bore of your existing pipe, or check the pipe's printed markings. Standard PVC pressure pipe is sized by nominal ID, so a 50 mm pipe takes the 50 mm flange. If you are unsure, contact us with your pipe's outer diameter (OD) and we can confirm the correct fit.

No. These fittings are manufactured from rigid PVC, which is rated for cold water and general water supply service only — typically up to approximately 60 °C (140 °F) under low pressure. They are not suitable for hot water heating systems, steam lines, or applications where sustained elevated temperatures are expected. For hot water service, consider CPVC or metal flanges.

Use a PVC primer and PVC solvent cement rated for pressure pipe, conforming to ASTM D2564 or an equivalent standard. Apply primer to both the pipe end and the flange socket, allow it to flash off briefly, then apply cement and push the pipe firmly into the socket with a slight twist. Hold for 30 seconds and allow the joint to cure fully before pressurising — typically 24 hours at room temperature.

The number of bolt holes and their spacing vary by pipe size — larger flanges have more holes to distribute load. Exact bolt-hole count and diameter are size-dependent; see variant options or contact us to confirm for your specific size. As a general guide, smaller flanges (20–50 mm) typically use M6 or M8 fasteners, while larger flanges (90–200 mm) may use M10 or M12. Always verify before drilling.

Yes. Rigid PVC is resistant to corrosion, UV degradation (when painted or shielded), and common fertiliser and water treatment chemicals, making these flanges well-suited for irrigation manifold anchoring, outdoor riser pipe support, and garden water supply systems. For permanently exposed outdoor installations, consider painting the fitting or using a UV-stabilised PVC cement to extend service life.

The colour (White, Blue, Grey) is primarily for visual identification and aesthetic matching — for example, Blue is commonly used in potable water systems for quick identification, while Grey is standard in many drainage and general plumbing applications. All three colours are the same PVC material and construction. Pressure ratings do not differ by colour; confirm the rating for your specific size if required.
