Regarding plumbing and irrigation systems, PVC (Polyvinyl Chloride) fittings ensure seamless connections, leak-free installations, and efficient water flow. These versatile fittings are widely used in various industries, including agriculture, landscaping, and construction. 

PVC Coupling

A PVC coupling is a simple, straight connector that joins two pipes of the same size together. It is the most basic type of PVC fitting and is used when a straight, non-permanent connection is required. Couplings are typically slip fittings that slide over the ends of the pipes and can be secured using solvent cement.

PVC Elbow

PVC elbows, available in 45 and 90-degree angles, are used to change the direction of the pipe. These fittings allow for smooth turns and are commonly used in plumbing systems to navigate around corners or obstacles. They come in various sizes and can be slipped fittings or threaded for added security.


PVC tees are T-shaped fittings that allow for a branching connection. With a central inlet and two outlets, tees are used when a pipe needs to be split into two directions. They are commonly used in irrigation systems, sprinkler setups, and plumbing applications where a bifurcation of water flow is required.

PVC Cross

Like tees, PVC crosses are used to divide the water flow into multiple directions. However, unlike tees with one inlet and two outlets, PVC crosses have one and three outlets. These fittings are often used in complex plumbing systems where multiple lines need to be connected.

PVC Adapter

PVC adapters are fittings that connect pipes of different sizes or materials together. They can have slip or threaded connections on one end and a different-sized socket or thread on the other. Adapters are handy when transitioning from PVC to metal pipes or vice versa.

PVC Union

A PVC union is a type of fitting that allows for easy disassembly of pipes. It consists of three parts: a socket, a threaded end, and a nut. Unions are commonly used in applications requiring regular maintenance or repairs, as they provide a convenient way to disconnect and reconnect pipes without cutting or solvent welding.

PVC Ball Valve

PVC ball valves control the flow of water or other fluids in a pipeline. They have a spherical closure mechanism (the “ball”) with a hole through it. When the ball is rotated 90 degrees, the hole aligns with the pipe, allowing the flow, and when turned 90 degrees again, the hole is perpendicular to the tube, blocking the flow. Ball valves provide a reliable and efficient shut-off solution.
