Connect different components such as couplings and stop the flows such as Caps. There are different types of pipe fitting used in piping. Pipe Fittings used in piping work are listed below. 1. Elbow 2. Tee 3. Reducer 4. Union 5. Coupling 6. Adapters 7. Olet (Weldolet, Sockolet, Elbowlet, Thredolet, Nipolet, Letrolet, Swepolet) 8. Cap 9. Nipple 10. Plug 11. Flanges
