PVC pipe fittings are molded plastic components (like elbows, tees, couplings, caps) that connect, redirect, branch, or end Polyvinyl Chloride (PVC) pipes to build plumbing, irrigation, and drainage systems, creating watertight joints for fluid flow in residential, commercial, and industrial settings, known for being affordable, chemical-resistant, and durable. They join pipes in various configurations (straight, turns, splits) and use methods like solvent cement, threading, or push-fit for secure connections, with common types including elbows for turns, tees for branching, and couplings for straight connections.
