PVC Unions are designed to fit two PVC pipes together and act just like a coupling, but unlike a coupling, PVC Unions can be easily removed and replaced. When used on irrigation valve installations, PVC Unions can allow for a quick and easy valve change outs when repairs are needed. They can also be used on temporary PVC lines and removed when no longer needed.
PVC Union Fittings come in two different types, Schedule 40 and Schedule 80. PVC Unions are available in Slip x Slip, Slip x Thread and Thread x Thread PVC Pipe Unions.

Schedule 80 PVC Union are general gray in color and designed to handle water pressures of 300 psi and water temperatures up to 140 degrees and are usually use in projects that support higher pressures. Meets NSF and ASTM D2464 and D2467 requirements. Manufactured from PVC Type 1, Grade 1.
PVC, Schedule 40 and Schedule 80 fittings are very versatile and can be used to distribute air or water at high and low pressures. PVC fittings are also easy to install and generally cheaper than alternative materials.
