PVC Floor Flange Pipe Fitting Grey Wall Mount Fittings Solvent Weld 20mm~200mm

Match the inside diameter (ID) listed in the variant options to the outside diameter (OD) of your pipe. Standard uPVC solvent weld pipe OD follows nominal pipe sizing — for example, a DN20 pipe has an OD of approximately 20mm. If you are unsure, measure the pipe OD with calipers and select the matching socket size.

These flanges are designed for drainage, waste, and vent (DWV) and cold-water distribution applications. They are not rated for continuous high-pressure service or hot-water lines above approximately 60 °C. For pressure-rated installations, verify the pressure class with your local plumbing code requirements.

Yes. Rigid uPVC is inherently resistant to rust, oxidation, and attack from common drain chemicals, mild acids, and alkalis found in household and light commercial waste streams. It is not suitable for concentrated solvents or aromatic hydrocarbons.

Use a standard grey or clear uPVC solvent cement that meets your local plumbing standard (e.g., ASTM D2564 or AS/NZS 3879). Clean and dry both the pipe OD and the flange socket, apply a thin even coat of cement to both surfaces, push firmly together with a slight twist, and hold for 30 seconds. Allow the joint to cure fully before pressurising or flowing water.

The number and diameter of fixing holes varies by flange size. Smaller sizes (20–50mm) typically have 4 holes on a compact bolt circle; larger sizes (63–200mm) may have 4–6 holes. Use appropriate masonry anchors, wood screws, or stainless steel bolts depending on your substrate. Contact us to confirm hole dimensions for your specific size before purchasing fasteners.

Yes. The flat flange face is suitable for mounting against any flat, solid surface — concrete floors, timber sub-floors, masonry walls, or framed stud walls with a backing plate. Ensure the mounting surface is level and the pipe is properly supported to avoid stress on the joint.

Multi-piece packs (3, 5, or 10 Pcs) offer a lower per-unit cost and are ideal for new construction rough-ins, multi-outlet drainage systems, or keeping spares on hand for maintenance. Single-piece packs are best for one-off repairs or when you only need a single connection point.
