PVC pipe fittings come in various types to ensure efficient water flow and strong connections in plumbing systems. Common types include elbows for direction change, tees for branching, couplings for joining pipes, and adapters for connection to other materials. Unions allow easy disassembly, while caps and plugs seal pipe ends. Cross fittings and reducers help manage complex networks. Each type of PVC pipe fitting ensures durability, leak resistance, and seamless installation in residential and industrial applications.
