Nipples: Used to connect two straight sections of pipe.
Elbows: Used to change the direction of pipes; common angles are 90 degrees and 45 degrees.
Tees: Provide a branch point, allowing flow from a main line to a branch line or to merge two lines.
Crosses: Form a cross shape, allowing connections in four directions.
Reducing Fittings: Used to connect pipes of different diameters.
Caps: Used to seal the end of a pipe.
Unions: Quick-connect fittings for easy disassembly and maintenance.
Threaded Fittings: Features threads for easy connection to other threaded components.
