Sch 80 PVC Unions

Unions work much like couplings, fitting two pipes together. The difference between unions and couplings is the ease at which unions can be removed and replaced. Because they do not require any adhesive, they can quickly be removed and replaced when changing a layout or setup. This makes Schedule 80 PVC unions the ideal choice for applications that may need to be changed and adjusted frequently.

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

Schedule 80 PVC unions connect pipes of similar sizes. The unions are particularly lightweight and come in a range of sizes from ΒΌ of an inch to 4 inches. They can be either slip socket or threaded, depending on the application they will be used for. These PVC unions feature thicker Schedule 80 PVC, giving them a durability above that of their Schedule 40 counterparts. This improves the durability of the entire system, while still maintaining the ease of use of unions and replacement that makes unions so popular.

Because they are made from PVC and not metal, these unions are smooth on the inside. This means that there is limited friction interrupting the flow, making these unions ideal for applications that require steady flow. Because of their durability, these Schedule 80 PVC unions are more resistant to corrosion, cold and heat than the thinner Schedule 40 options. This allows them to be used in chemical plants, where solvents, acids and bases could create a problem for less durable materials. PVC can withstand temperatures over 100 degrees Fahrenheit, so they can be used in chemical mixing applications. They can also withstand cold materials, so they can be used to carry cooled liquids.

Because they handle high pressures so well, Schedule 80 PVC unions are well suited for irrigation applications as well as manufacturing and chemical processing plants. The ability to withstand damage from soil and temperature changes makes these unions particularly well suited for outdoor applications.
