When a leaking joint or a mismatched fitting derails a plumbing project, the root cause is almost always a component that wasn't built to spec. DIYers, plumbers, and facilities maintenance teams who need dependable UPVC PVC pipe fittings in a range of configurations can stop hunting across multiple suppliers — this listing covers tee, straight, and elbow styles in a single dark-grey solvent-weld range.
Each fitting is moulded from unplasticised PVC (UPVC) in a consistent dark-grey finish. Inner diameters span 20 mm to 50 mm (approximately ¾ in to 2 in), covering DN15 through DN40 nominal pipe sizes. Straight couplings join two pipe runs end-to-end; elbow fittings redirect flow at 90°; tee fittings branch a single run into two directions. Wall thickness is proportional to pipe diameter and typically ranges from 2 mm to 4 mm (0.08 in to 0.16 in) depending on the size selected.
Typical applications include cold-water supply lines in residential and light-commercial builds, irrigation and garden water distribution systems, and drainage or waste-pipe repairs where a solvent-weld UPVC pipe fitting for 20 mm to 50 mm pipe is required. The multi-piece quantity options make this listing equally suited to single-repair jobs and small-batch plumbing projects.

Measure the outer diameter of your existing pipe, then match it to the corresponding DN nominal size: DN15 ≈ 20 mm ID fitting, DN20 ≈ 25 mm ID fitting, DN25 ≈ 32 mm ID fitting, DN40 ≈ 50 mm ID fitting. If you are unsure, use a vernier caliper on the pipe end for an accurate reading before ordering.
UPVC solvent-weld fittings are widely used in residential cold-water pressure systems. The exact pressure rating depends on the specific size and wall thickness. For confirmed working-pressure figures, please contact us with your size selection before purchase.
UPVC does not rust or corrode and is resistant to most household chemicals, chlorinated water, and mild acids. It is not recommended for hot water above approximately 60 °C (140 °F) or for concentrated solvents. For cold-water and irrigation use, the material offers long service life under normal conditions.
Yes — the socket dimensions follow standard UPVC pipe schedules for DN15–DN40. Always verify that your pipe's outer diameter matches the fitting's inner diameter before applying solvent cement, as slight variations can exist between pipe brands and manufacturing standards.
Use a UPVC-rated solvent cement (also called PVC pipe glue or solvent weld adhesive). Clean and dry both the pipe end and the fitting socket, apply a thin, even coat of primer if required by your local code, then apply 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 pressurising.
Choose a straight coupling to join two lengths of pipe in a continuous run. Choose a 90° elbow to change the pipe direction by 90° — useful for turning a corner or routing around an obstacle. Choose a tee when you need to branch one pipe run into two directions, such as adding a new outlet to an existing supply line.
UPVC has moderate UV resistance and the dark-grey pigment provides additional protection compared to white PVC. For fully exposed outdoor installations with prolonged direct sunlight, consider painting the fittings with a water-based exterior paint or using UV-stabilised pipe insulation to extend service life.
