White PVC 90° Elbow Joints — Reliable Water Supply Pipe Fittings for Every Diameter
When a plumbing run needs to change direction without losing flow integrity, the wrong fitting creates leaks, stress cracks, and callbacks. Contractors, irrigation installers, and serious DIYers who work with PVC water supply lines need a 90-degree elbow that seats cleanly, holds pressure, and resists the slow degradation that cheaper fittings develop over time.
These white PVC 90-degree elbow joints are available in 12 sizes from 16mm (approx. 5/8 in.) to 160mm (approx. 6-1/4 in.), covering the full range of residential and light commercial water supply pipe diameters. Each elbow is injection-moulded from rigid PVC with a smooth interior bore and a consistent wall thickness designed for solvent-cement socket connections.
Typical applications include domestic cold-water supply runs, garden and drip irrigation manifolds, rainwater harvesting pipework, and above-ground drainage redirects — anywhere a clean 90° turn is needed in a PVC pressure or gravity-flow system.

Compatibility: Designed for standard PVC pressure pipe (Schedule 20 / Class C equivalent). Confirm pipe OD against selected size before ordering. Solvent-cement joint — not suitable for push-fit or threaded connections.
✅ Key Features of These PVC 90-Degree Elbow Fittings
-
📐 12 sizes in one listing (16mm–160mm): Select the exact diameter you need — from small-bore irrigation lines up to large-diameter supply mains — without sourcing from multiple suppliers.
-
🔄 True 90° turn geometry: Consistent elbow angle ensures predictable flow direction changes with no angular variance that could misalign downstream pipe runs.
-
🧱 Rigid PVC construction: Injection-moulded from rigid PVC compound with uniform wall thickness, providing structural stability under sustained water pressure in cold-water supply applications.
-
🔒 Socket-end solvent-cement joint: Both ends are machined to accept standard PVC solvent cement, creating a chemically fused, leak-resistant bond that does not rely on mechanical compression.
-
🌿 Corrosion and scale resistant: PVC does not rust, corrode, or accumulate mineral scale the way metal fittings do, maintaining bore diameter and flow rate over the service life of the installation.
-
🏗️ Suitable for irrigation, plumbing & rainwater systems: Rated for cold-water supply and gravity-flow drainage applications including garden irrigation manifolds, rainwater diverters, and residential supply runs.

❓ Frequently Asked Questions
Which size elbow do I need for my pipe?
Match the elbow size to the outer diameter (OD) of your PVC pipe, not the nominal bore. For example, a pipe labelled "20mm" typically has a 20mm OD and requires the 20mm elbow. If you are unsure, measure the outside of your pipe with calipers before ordering. Available sizes run from 16mm (approx. 5/8 in.) to 160mm (approx. 6-1/4 in.).
Can these elbows handle mains water pressure?
These fittings are designed for cold-water supply and irrigation applications. Typical residential mains pressure in the US ranges from 40–80 psi. For confirmation of the pressure rating for your specific size, please contact us before ordering, as wall thickness and rated pressure vary by diameter.
Are these fittings suitable for hot water lines?
No. Rigid PVC is rated for cold-water supply only (generally up to 60°C / 140°F under low pressure, but not recommended for sustained hot-water service). For hot water lines, use CPVC or copper fittings instead.
What adhesive or cement should I use to join these elbows?
Use a standard PVC solvent cement (also called PVC glue or PVC primer + cement system) rated for pressure pipe. Apply primer to both the pipe end and the socket, then apply cement and push the pipe firmly into the socket with a quarter-turn. Allow the joint to cure per the cement manufacturer's instructions before pressurising the line.
Will these fittings corrode or degrade outdoors?
PVC is inherently corrosion-resistant and will not rust or scale. However, prolonged direct UV exposure can cause surface chalking and gradual embrittlement over several years. For above-ground outdoor installations with direct sun exposure, consider wrapping the fitting or painting with a UV-resistant coating to extend service life.
Can I use these for drainage or waste lines, not just supply?
Yes, for gravity-flow drainage applications these elbows are suitable. Note that dedicated DWV (drain-waste-vent) systems often use a different pipe OD standard and swept (long-radius) elbows rather than sharp 90° turns. Confirm your pipe OD and flow requirements before using a sharp 90° elbow in a drainage run.
Are these compatible with push-fit or compression fittings?
No. These are socket-end solvent-cement fittings only. They are not compatible with push-fit (e.g., SharkBite-style) or compression-type connections. If your system uses push-fit fittings, you will need a different product type.
