PVC (Polyvinyl Chloride) pipe fittings, commonly used in plumbing and irrigation systems.
PVC Elbows:
The L-shaped pieces are PVC elbows, used to change the direction of a pipeline, typically at a 90-degree angle.
PVC Couplings/Connectors:
The straight, cylindrical pieces are likely PVC couplings or straight connectors, used to join two pipes of the same or different diameters in a straight line.
PVC Caps:
The smaller, cup-shaped items could be PVC caps, used to seal the end of a pipe.
Applications:
These fittings are essential for creating complex plumbing systems, allowing for branching, extending, and changing the direction of water flow in various applications like water supply, drainage, and irrigation.
