Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Schedule 40 fittings have thinner walls than Schedule 80 fittings and are typically used in commercial and residential applications.

Schedule 80 fittings have thicker, stronger walls than Schedule 40 fittings for heavy duty, industrial chemical processing applications.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. Flanges have the chemical resistance to stand up to a wide variety of acids, solvents, and other harsh substances. Also known as Class 150 flanges, they have thick, strong walls for heavy duty chemical processing applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. When connecting to pipe, apply a non-hardening, plastic-compatible sealant to the male pipe threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the flange, then wrench-tighten one to two turns.

Warning: Never use plastic pipe flanges and pipe with compressed air or gas.
