PVC Water Pipe Fittings Drainage Couplers Adapter Cross Tee Elbow 16mm-200mm

Match the fitting's inner diameter (ID) to your pipe's outer diameter (OD). For standard PVC pipe, the pipe's nominal size typically corresponds to the fitting's listed inner diameter. Measure your existing pipe's OD with calipers and compare it to the fitting socket dimensions. When in doubt, select the next size up and test-fit before cementing.

These rigid PVC fittings are suitable for low-to-moderate pressure water applications such as drainage, irrigation, and pond circulation. For high-pressure potable water supply lines, verify the pressure rating of the specific size variant you select. Larger diameters (110mm and above) are generally intended for gravity-fed drainage rather than pressurized supply.

Yes. Rigid PVC is inherently corrosion-resistant and compatible with most common water treatment chemicals including chlorine at typical municipal concentrations. It will not rust, pit, or scale like metal fittings. Avoid prolonged contact with strong solvents, concentrated acids, or aromatic hydrocarbons, which can degrade PVC over time.

Use a 90° elbow for sharp right-angle turns, a 45° elbow for gentler directional changes that reduce flow restriction. A tee splits or combines flow at a T-junction; a cross handles four-way intersections. The 3-way, 4-way, 5-way, and 6-way connectors are ideal for manifold or structural framework builds. The inlet/outlet water elbow is designed for tank or reservoir connections where a right-angle port is needed at a wall or base.

These fittings are designed to accept standard PVC pipe of the corresponding inner diameter. Most common PVC drainage and irrigation pipe sold in hardware stores follows DIN or ISO dimensional standards. Confirm your pipe's OD matches the fitting's socket before purchasing. If you are mixing pipe from different manufacturers, a test-fit before cementing is always recommended.

Use a PVC solvent cement appropriate for the pipe diameter. Apply PVC primer to both the pipe end and fitting socket, then apply solvent cement and push the pipe firmly into the socket with a slight twist. Allow the joint to cure per the cement manufacturer's instructions before pressurizing the line — typically 15–30 minutes for small diameters and up to 24 hours for larger sizes.

Yes, PVC is suitable for both outdoor and underground installations. For outdoor above-ground use, prolonged UV exposure can cause surface chalking over time; painting with a UV-resistant paint or using gray or black variants can extend the appearance life. For underground drainage, ensure the trench is properly bedded and backfilled to prevent point loading on the fittings.
