PVC fittings are components used in polyvinyl chloride (PVC) piping systems to connect and redirect pipes, change direction, regulate flow, and adapt to different pipe sizes and types. These fittings are essential for constructing and maintaining plumbing, irrigation, drainage, and other fluid transportation systems. PVC fittings come in various shapes and configurations, including elbows, tees, couplings, adapters, reducers, and valves. They are designed to provide secure and leak-proof connections between PVC pipes, ensuring the integrity and efficiency of the piping system.
