20-50mm PVC Pipe Fittings Elbow Tee 3 4 5-Way Plumbing Connector Solvent Weld

Match the fitting's inner diameter (ID) to the outer diameter (OD) of your PVC pipe. For example, a 20 mm fitting accepts pipe with a 20 mm OD. If you are unsure, measure the pipe OD with calipers or check the pipe's printed markings. Using a fitting that is even 1 mm too large will result in a loose bond that can fail under pressure.

PVC solvent weld fittings are widely used in cold potable water systems. Confirm the specific fitting and cement you select carry the relevant local certification (e.g., NSF/ANSI 61 in North America, WRAS in the UK) if your jurisdiction requires it for drinking water contact. The fittings are not rated for hot water above approximately 60 °C (140 °F).

Use a standard PVC solvent cement (also called PVC glue or PVC adhesive) rated for the pipe class and application. For sizes 32 mm and above, apply a PVC primer first to soften the socket surface before cementing — this is required by most plumbing codes and significantly improves bond strength. Follow the cement manufacturer's cure time before pressurising the line.

Yes. The UV-stabilised PVC formulation resists surface degradation in exposed outdoor conditions. For buried installations, PVC is chemically resistant to most soils and groundwater. Ensure the trench is free of sharp stones that could stress the pipe wall, and follow local codes for burial depth and bedding material.

A Tee has three ports at 90° — one inlet and two outlets (or one straight run plus one branch). A Cross has four ports, allowing two straight runs to intersect. A Y-Piece has three ports arranged at approximately 45°, which produces a gentler flow transition and lower turbulence than a standard Tee — making it preferred for drainage and waste lines where solids may be present.

No. Once cured, a solvent weld joint is permanent — the cement chemically fuses the pipe and fitting into a single piece. If a joint is incorrectly assembled, cut it out with a pipe cutter or hacksaw and install a new fitting with a short coupling section. This is why dry-fitting and marking alignment before applying cement is strongly recommended.

Multi-way elbows allow multiple pipes to meet at a single junction point — useful in irrigation manifolds, compressed-air distribution headers, and modular display or structural frameworks built from PVC pipe. A 3-Way Elbow connects three pipes at a corner; a 6-Way Elbow connects six pipes meeting at a central hub. Select the number of ports that matches the branches required at that node in your system.
