U-PVC Fittings
Our U-PVC Fittings aren't just limited to elbows-they're a full range of rigid connection components built for U-PVC piping systems, covering everything you need for a complete, leak-free setup. Made from the same high-grade unplasticized polyvinyl chloride (UPVC) as our elbows-y'know, the tough, rigid stuff, not the bendy hose PVC-these fittings are designed to handle low to medium-pressure applications, from residential plumbing to light commercial drainage and even small-scale irrigation. Unlike PERT fittings that rely on fusion, all our U-PVC Fittings use either slip-fit (glued with solvent cement) or threaded connections, whichever works best for your job. Sizes range from 16mm (tiny residential lines) up to 200mm (small commercial runs), with standard white or gray finishes that blend right in with existing U-PVC piping. The design's all about functionality: smooth inner walls to prevent clogs and pressure drops, uniform wall thickness for durability, and a rigid build that holds its shape over time. Lightweight, corrosion-resistant, and way less prone to gunk buildup than metal fittings-they're straightforward, reliable, and built to last, as long as you install 'em right (no cutting corners on the glue, trust me).

Key Features
• Full Range of U-PVC Components: Not just elbows-we've got couplings, tees (equal and reducing), reducers, end caps, and adapters, all made from the same high-grade UPVC. One stop for all your U-PVC connection needs, no need to source from multiple places.
• Rigid, Durable UPVC Construction: High-grade unplasticized PVC keeps its shape for fixed piping runs-no bending, sagging, or warping over time. Just be careful with handling; they're rigid, so they can chip or crack if dropped from height (we've all fumbled a fitting before).
• Versatile Angle & Configuration Options: Beyond the 45° and 90° elbows, our tees split flow, couplings join pipes end-to-end, reducers adapt different sizes, and end caps seal open lines. Custom configurations are available on request, though they take a little extra time.
• Dual Connection Types: Slip-fit (solvent cement) is quick and easy for residential jobs-perfect for sink drains or toilet lines. Threaded connections are great for commercial setups where you might need to disassemble and repair lines later. Both seal tight, but only if you apply the glue properly (don't rush this step).
• Smooth Inner Walls for Unobstructed Flow: Every fitting has smooth inner surfaces, no sharp edges or rough spots where debris can build up. Critical for drainage systems-clogs happen fast with cheap, poorly finished fittings, and nobody wants that hassle.
• Chemical & Corrosion Resistant: Holds up to common household chemicals like bleach, drain cleaners, and even mild detergents. No rust, no corrosion, way more reliable than metal fittings that get gunky and degrade over time.
• Lightweight & Easy to Handle: Easy to carry around jobsites, no heavy lifting needed-perfect for contractors moving from one area to another. Installation's straightforward, even for beginners, as long as you follow the solvent cement instructions.
• Standard Sizes & Colors: Available in 16mm to 200mm, covering most residential and light commercial needs. Standard white or gray finishes blend seamlessly with existing U-PVC piping, no unsightly mismatches.
• Cost-Effective & Long-Lasting: Affordable upfront, and their durability means you won't be replacing them often. Way cheaper than metal fittings in the long run, especially with no rust or corrosion to worry about.
