UPVC PVC Pipe Fittings — Elbow, Tee & Straight Couplings for Reliable Plumbing Runs
When a plumbing run demands a direction change, branch split, or inline join, the wrong fitting can mean leaks, callbacks, and wasted time. These dark grey UPVC pipe fittings are engineered for residential and light-commercial drainage, waste, and vent (DWV) systems where dimensional accuracy and chemical resistance matter. Suitable for DIY renovers, licensed plumbers, and facilities maintenance teams alike.
Each fitting is manufactured from unplasticised PVC (UPVC) in a uniform dark grey finish. Available in three fitting types — 90° Elbow, Straight Coupling, and Equal Tee — across four nominal bore sizes: 63 mm (DN50), 75 mm (DN65), 90 mm (DN80), and 110 mm (DN100), approximately 2½", 3", 3½", and 4" respectively. Wall thickness and overall body dimensions conform to standard DIN/AS/NZS pipe fitting profiles for each DN class.
Typical applications include underground stormwater drainage connections, above-slab sanitary waste lines, irrigation manifold branches, and conduit routing in commercial fit-outs. The solvent-weld socket design creates a chemically fused, leak-free joint compatible with standard UPVC solvent cement — making these fittings a go-to choice for UPVC pipe elbow replacement, tee branch additions, and straight coupling repairs.
🔗 Compatible with standard UPVC/PVC pressure and DWV pipe in DN50, DN65, DN80, and DN100 nominal sizes. Verify pipe OD against fitting socket ID before installation.
✅ Key Features of These UPVC PVC Pipe Fittings
📐Four Bore SizesCovers DN50 (63 mm), DN65 (75 mm), DN80 (90 mm), and DN100 (110 mm) — one product listing for the full range of common residential and light-commercial pipe diameters.
🔀Three Fitting Geometries90° Elbow for direction changes, Equal Tee for branch splits, and Straight Coupling for inline joins — select the exact configuration your run requires.
🛡️Corrosion-Resistant UPVC BodyUnplasticised PVC resists rust, scale, and most household chemicals, making these fittings suitable for both above-ground and buried drainage applications.
🔩Solvent-Weld Socket DesignStandard spigot-and-socket profile accepts UPVC solvent cement for a chemically fused, pressure-rated joint that does not rely on mechanical clamps or O-rings.
🎨Uniform Dark Grey FinishConsistent dark grey pigmentation throughout the body — not a surface coating — so colour remains stable even if the fitting is cut or abraded during installation.

❓ Frequently Asked Questions
Which size fitting do I need for my pipe?
Match the fitting's Inner Diameter (ID) to your pipe's Outer Diameter (OD) — UPVC pipe is sized by nominal bore (DN), and the socket ID is machined to accept the corresponding pipe OD. Measure your existing pipe OD with calipers: DN50 pipe is typically 63 mm OD, DN65 is 75 mm OD, DN80 is 90 mm OD, and DN100 is 110 mm OD. If in doubt, contact us to confirm before ordering.
Can these fittings be used for underground drainage?
Yes. UPVC is widely used for buried drainage and stormwater applications. Ensure the trench is bedded with compacted sand or fine gravel to provide uniform support, and that the pipe and fittings are rated for the burial depth and any traffic loading in your application. Check local plumbing codes for specific requirements.
What solvent cement should I use with these fittings?
Use a UPVC-rated solvent cement (also labelled PVC solvent weld cement) that meets your local plumbing standard (e.g., AS/NZS 3879 or ASTM D2564). Clean and dry both the pipe spigot and fitting socket, apply a thin even coat of cement to both surfaces, push together with a quarter-turn, and hold for 30 seconds. Allow full cure time before pressure testing.
Are these fittings compatible with standard grey PVC pressure pipe?
These fittings are designed for UPVC/PVC pipe with standard DIN or AS/NZS OD dimensions in the corresponding DN class. Confirm that your pipe's OD matches the fitting socket ID listed above. Pressure-rated pipe and DWV pipe in the same DN class typically share the same OD, but wall thickness differs — the fitting socket accommodates the OD regardless of wall thickness.
How do I choose between an Elbow, Tee, and Straight Coupling?
Select a 90° Elbow when your pipe run needs to change direction by 90°. Choose an Equal Tee when you need to branch a run into two directions of the same bore size. Use a Straight Coupling to join two lengths of pipe in a continuous inline run, or to repair a damaged section by cutting out and replacing it.
Can I disassemble a solvent-welded joint if I make a mistake?
No — solvent welding creates a permanent chemical fusion between the fitting and pipe. If a joint is incorrectly assembled, the affected section must be cut out and replaced with a new fitting and a short pipe offcut. This is why dry-fitting and marking alignment before applying cement is strongly recommended.
Are these fittings suitable for hot water lines?
Standard UPVC fittings are rated for continuous service up to approximately 60 °C (140 °F). They are not suitable for hot water supply lines that regularly exceed this temperature. For hot water applications, consider CPVC or PP-R fittings rated for higher temperatures. These fittings are intended for cold water drainage, stormwater, and DWV use.
