Schedule 80 PVC Unions

Schedule 80 PVC unions are used to create a secure and detachable connection between Schedule 80 PVC pipes or components in more demanding applications. Their primary purpose is to allow for easy disassembly and reassembly at the joint created by the union when needed for maintenance, repair, or modifications. Unions differ from couplings, which require cutting or special tools for pipe disconnection, as they feature a built-in threaded joint that can be unscrewed for disconnection. Schedule 80 PVC unions are valued for their ability to withstand higher working pressures, conditions, and corrosion over Schedule 40 components. The fittings are essential and commonly used in industries such as water treatment, wastewater handling, chemical distribution, agriculture and landscaping irrigation systems, industrial and manufacturing settings, high pressure applications, and plumbing systems that require regular maintenance.

Sch 80 PVC union sizes range from 1/4" to 4” in diameter in both standard and metric sizing. Union fittings are available in either Sch 80 PVC slip x slip, Sch 80 PVC threaded, or combination slip x thread union types. Union slip x slip fittings have two socket end joints for solvent or glue connection. Threaded unions have two female pipe threaded (FPT) ends for mating with male pipe threaded (FPT) components. Combination unions have socket by thread ends for connecting two pipe parts of different connection options. 

Our Schedule 80 PVC unions are USA made by leading manufacturers and engineered for reliable performance, long service, and leak proof safety. The unions meet ASTM D1784, ASTM D2464, ASTM D2467, and NSF standards and specifications for product quality and use. Standard ASTM D1784 ensures the purity and grade of PVC material used in production. Standards ASTM D2464 and D2467 cover the required specs on pressure, measurements, and connections for Schedule 80 plumbing. These Schedule 80 PVC unions are NSF approved for potable water systems and freshwater applications.

PVC is resistant to many chemicals and corrosive materials. This resistance makes Sch 80 PVC unions suitable for many industrial and chemical handling applications. For chemical plumbing systems and conveyance, always verify chemical compatibility before use.

Schedule 80 PVC unions are frequently used in plumbing applications to join components that regularly need to be accessible for maintenance or repair. Common applications for heavy duty unions include water treatment plants, industrial chemical processing facilities, manufacturing plants, high-pressure irrigation systems, agriculture and commercial plumbing setups, large aquariums and aquatic systems.

Schedule 80 PVC unions are used in plumbing applications to join components that regularly need to be accessible for maintenance or repair. Their function is similar to couplers but can be easily disassembled when necessary without causing damage to the piping network or parts. Their heavy duty engineering and Schedule 80 thickness are ideal for higher pressure plumbing systems and chemical handling applications. Purchase options for Sch 80 unions include single, box, and pallet orders. Contact our support experts for more details or more information on contractor pricing.
