Regular PVC pipe fittings come in various shapes like elbows, tees, and couplings, allowing for customized pipe layouts with turns, branches, and flow control. They typically connect using solvent cement for a permanent bond, although some types offer threaded connections.On the other hand, PVC manifold fittings consolidate multiple connection points into a single unit. Imagine a multi-port hub – that's a manifold. These are ideal when you need to efficiently connect several pipes from a single source, like feeding different irrigation zones or connecting multiple fixtures in plumbing. Manifold fittings usually rely on threaded connections for easier assembly and disassembly compared to solvent-cemented regular fittings.
