Schedule 80 PVC Couplings

Schedule 80 PVC couplings are short fittings used to connect two lengths of plain end Schedule 80 PVC pipe to extend a straight run when additional distance is required. They are used to create a straight line connection joint to allow the continuous flow of media through a pipeline. The couplings are made from PVC, a durable plastic, and manufactured to Schedule 80 standards, which means the couplers have thicker walls than Schedule 40 PVC couplers. The thicker walls of Sch 80 PVC give couplings improved physical and chemical strength and the ability to withstand higher fluid pressures within the conveyance system. Schedule 80 PVC couplings are primarily used in Schedule 80 plumbing applications where the pipe system will experience higher internal pressure or potentially greater physical, chemical strain. 

Sch 80 PVC coupling sizes range from 1/4" to 12” in diameter. Large diameter Sch 80 socket couplings from 14” to 24” in size are available on request by quote. Reducer couplings are used to connect two different sized pipe lengths and are available in a range of sizes from 3/4" x 1/2" up to 10” x 6” in reducing diameters. 

Connection options for heavy duty couplings include Schedule 80 slip couplings and Schedule 80 threaded couplings. Slip couplings feature socket x socket ends for making glue or solvent weld joint connections. Threaded couplings feature FPT x FPT ends for making thread-joint connections with male ended piping.

Crafted for superior performance and safety, our Schedule 80 PVC couplings are proudly manufactured in the USA according to the industry standards set by ASTM D1784, ASTM D2464/2467, and the NSF. ASTM D1784 ensures quality, uniform PVC material. ASTM D2464/2467 guarantees precision dimensions, connections, and pressure ratings for Schedule 80 applications. NSF certification validates that the fittings are safe for freshwater use and in potable water systems.

Heavy duty Sch 80 PVC couplings are commonly used across applications and plumbing projects when needing to join two pipes to increase pipeline reach for making connections. Example applications include high pressure water systems such as irrigation systems, pools, spas, and underground water lines, in industrial processes such as chemical processing plants and wastewater treatment facilities, and in manufacturing to handle chemicals, solutions, ingredients, and proprietary materials.

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