Sch 80 CPVC Unions

Designed for industrial applications, Schedule 80 CPVC unions carry several benefits in addition to the ease of installation and removal. First, the thicker Schedule 80 model is more resistant to corrosion than the more commonly used Schedule 40. This means that these unions can be used in systems that carry acids, bases and solvents, which might be common in a factory, lab or chemical plant.

Our schedule 80 CPVC fittings meet ASTM D1784 Standards and are NSF-14 Certified.


The Schedule 80 CPVC is particularly smooth inside, so it reduces friction and allows for smooth flow without reducing the pressure. Also, the CPVC material can withstand extremely high temperatures, even up to 210 degrees Fahrenheit, so they can be used in systems intended to carry high temperature solutions. Similarly, the strong CPVC material is less likely to be damaged by cold fluids, so they can be used for chilled water distribution. Other applications include waste water treatment, plating and chemical drainage.

These Schedule 80 CPVC unions allow for the joining of two pipes in a CPVC system. The durable, tested CPVC material gives these unions strength beyond their PVC counterparts, while the thicker Schedule 80 durability also improves the durability of the product.

Unions are similar to couplings in that they join two pipes together. However, unions, unlike couplings, are specifically designed to be easy to install and replace since they do not require adhesive to be attached.

Schedule 80 CPVC unions are designed to connect pipes of the same size to each other. These lightweight unions are available in a wide range of sizes, with the smallest being ΒΌ inch and the largest being 4 inches. They are dark gray in color, and both slip socket and threaded unions are available. For applications that require ease of installation and repair combined with lab-tested durability, Schedule 80 CPVC unions are the best choice for joining two pipes.
