PVC Reducing Tee Pipe & Fittings Solvent Weld Pressure Adapter Connector Grey

Measure the outer diameter (OD) of both your main run pipe and the branch pipe you intend to connect. The first number in the size designation (e.g., 63mm in "63mm × 32mm") is the run port OD; the second number is the branch port OD. Match these to your pipe ODs — not the nominal bore — to ensure a full-depth socket fit and a sound solvent bond.

These are pressure-rated solvent weld fittings designed for use with Class C or Class D uPVC pressure pipe. Typical residential mains pressure (up to 10–12 bar depending on size) is within the design envelope of standard uPVC pressure fittings. For confirmed pressure ratings at a specific size, please contact us before ordering for critical or high-pressure applications.

uPVC is rated for cold water service only — typically up to 60°C maximum, with pressure ratings derated at elevated temperatures. For hot water systems, CPVC or PP-R fittings are more appropriate. For chemical compatibility, check the specific chemical against a uPVC resistance chart, as some solvents and acids will degrade PVC.

Use a PVC-specific solvent cement (sometimes labelled "PVC pipe cement" or "uPVC solvent") along with a compatible PVC primer/cleaner. Do not use ABS cement or multi-purpose adhesives — they will not form a pressure-rated bond. Follow the cement manufacturer's cure time instructions before pressurising the system, typically 15–30 minutes at 20°C ambient.

Grey uPVC has reasonable UV resistance for short-term above-ground exposure, but for permanent outdoor installations in direct sunlight, wrapping with UV-protective tape or painting with a water-based exterior paint is recommended to extend service life. For buried installations, uPVC is well-suited — it resists soil moisture, common fertilisers, and mild acids found in garden soils.

Multi-packs (2, 3, 5, 8, or 10 pcs) offer a lower per-unit cost compared to single-piece orders, making them ideal for irrigation manifold builds, new pipe runs with multiple branch points, or keeping spares on hand for maintenance. If you are installing more than two tees of the same size, a 5-pack or 10-pack typically delivers the best value.

An equal tee has all three ports at the same diameter, so the branch flow exits at the same pipe size as the main run. A reducing tee has a smaller branch port, allowing you to step down to a narrower pipe on the branch without adding a separate reducer coupling. This saves a fitting, reduces potential leak points, and keeps the branch run more compact — particularly useful in tight manifold layouts.
