Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. They have the chemical resistance to stand up to acids, solvents, and other harsh substances. Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are also known as Pressure Class 150 flanges.

The inside of these fittings won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes it easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC fittings.

The grooved ends on these flanges connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. Flanges have excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances. They are also known as Victaulic flanges.
