UPVC Elbow Fittings
Our UPVC Elbow Fittings are made from high-grade unplasticized polyvinyl chloride (UPVC)-y'know, the rigid kind, not the bendy PVC you use for hoses. They're designed to connect two UPVC pipes at fixed angles, mostly 45° and 90°-those are our main ones, though we can do other angles if you ask. They come with either slip-fit or threaded connections, depending on what your project needs. Unlike PERT fittings that use fusion, these are installed with solvent cement-quick to put on, but you gotta have a steady hand. Mess that up, and you'll get leaks, trust me. Sizes go from 16mm (small residential lines) up to 200mm for small commercial drainage. Most are white or gray, standard colors so they blend in with your existing UPVC piping. The design's pretty straightforward-smooth inner walls to keep clogs and pressure drops away, and the rigid build keeps their shape over time. They're lightweight, don't rust or get gunked up, way better than metal elbows.

Key Features
• Rigid, Durable UPVC Build: High-grade UPVC keeps their shape for fixed piping-no bending or sagging. Just… be careful not to drop 'em from high up. They're rigid, so they can chip or crack if you're clumsy (we've all been there).
• Primary Angle Options: 45° is good for gradual turns, like drainage lines. 90° is for tight corners-under sinks, behind toilets, that sort of thing. Custom angles? Yeah, we can do those if you need 'em, just ask.
• Dual Connection Types: Slip-fit uses solvent cement, quick for residential jobs. Threaded is easier to take apart, which is nice for commercial setups. Both seal tight, but only if you install 'em right-don't cut corners on the glue.
• Smooth Inner Walls: No sharp edges or rough spots where debris can build up. That's important for drainage, 'cause clogs happen fast if you skip this part. Cheap elbows don't bother with smooth walls, and it shows.
• Chemical & Corrosion Resistant: Holds up to household stuff like bleach or drain cleaners. Doesn't rust, which is way better than metal elbows-those get gunky and corroded before you know it.
• Lightweight & Easy to Install: Easy to carry around jobsites, no heavy lifting. Installation's straightforward, just make sure you apply the solvent cement correctly. That's the key, really.
