Because of their durability and affordability, these schedule 40 PVC unions are commonly found in home plumbing and irrigation systems. Whoever, they are also commonly used when PVC is used to build temporary structures, such as outdoor tent frames. Because they are easily disassembled, they can connect pipes in a temporary building situation easily. The ends of the union ship easily inside the pipe to create a firm, but temporary, connection. Both slip socket and female pipe threaded ends are available with schedule 40 PVC unions.

The PVC material resists corrosion and rust and they hold up well when exposed to the sun, which makes these unions ideal for outdoor settings or underground irrigation systems. They can also be used in systems carrying highly corrosive fluids. The smooth interior wall helps the liquid to flow through the system without a reduction in flow common with other materials. Schedule 40 PVC unions are commonly used in smaller pipes, and they are available in sizes ranging from 1/2 in to 2 inches in diameter. The affordability and range of diameters makes these schedule 40 PVC unions a great choice for a semi-permanent connection.
