PVC 45 Degree Elbow Pressure Fittings Adhesive Water Pipe Fitting ID 20mm~ 200mm

Match the fitting's inner diameter (ID) to your pipe's outer diameter (OD) minus the wall thickness — or more simply, to the pipe's nominal bore. For example, a 20 mm nominal uPVC pipe typically has an OD of approximately 25 mm; the 20 mm fitting socket is sized to accept that pipe. When in doubt, measure your pipe's OD with calipers and contact us to confirm the correct socket size.

These are pressure-rated fittings designed for use on pressurized cold-water systems. The exact pressure rating (PN class) varies by size — larger diameters typically carry a lower PN rating. Refer to the variant-specific details or contact us to confirm the PN rating for your chosen size before installation on mains-pressure lines.

No. These uPVC fittings are rated for cold-water service only (generally up to 60 °C / 140 °F at reduced pressure). They are not suitable for hot-water heating systems, steam lines, or any application where sustained temperatures exceed the rated limit. For hot-water applications, consider CPVC or copper fittings instead.

Use a uPVC-compatible solvent cement (also called PVC solvent weld adhesive) that meets your local plumbing standard (e.g., ASTM D2564 in North America, or BS 6209 in the UK). Apply primer first on larger sizes (50 mm and above) for a stronger bond. Allow the joint to cure undisturbed for at least 15 minutes before handling, and avoid pressurizing the line for 24 hours after bonding.

The color options serve a practical identification purpose. White is commonly used for general utility or potable water lines. Blue is often associated with cold-water supply circuits, making it easy to distinguish supply from drainage at a glance. Grey is typically used for drainage, waste, or conduit runs. Choosing a consistent color for each system type simplifies future maintenance and reduces the risk of cross-connection errors.

uPVC is widely used in buried water and drainage applications because it resists soil corrosion and does not rust. For buried use, ensure the trench is properly bedded with compacted sand or fine gravel to support the pipe evenly, and allow the solvent joint to fully cure before backfilling. Check local plumbing codes for any additional requirements regarding burial depth and bedding material.

A 45° elbow produces a gentler directional change, which results in lower pressure drop (head loss) and reduced turbulence compared to a 90° elbow at the same flow rate. This makes 45° elbows the preferred choice in irrigation mains, pool circulation lines, and any system where maintaining flow efficiency matters. Two 45° elbows can also be combined to achieve a 90° offset with a longer sweep radius than a single 90° fitting.
