PPR fittings are components used to connect PPR pipes or transition from PPR pipes to other types of pipes. PPR fittings come in a variety of shapes and sizes to accommodate different pipe configurations and needs. Some common types of PPR fittings include elbows, unions, tees, crosses, reducers, and adapters. Elbows are used to change the direction of a pipe, usually 90 degrees. Unions are used to connect two PPR pipes of the same diameter. Tees are used to divide a single pipe into two or more branches. Crosses are used to connect four pipes at one point. Reducers are used to connect PPR pipes of different diameters. Adapters are used to connect PPR pipes to other types of pipes, such as metal pipes.
