Chemical-Resistant Duct and Fittings

Chemicals can eat away at most metal duct, but not this PVC system. It’s often used to exhaust corrosive gases, vapors, and fumes. Components press-fit together and secure with PVC pipe cement.

Duct

Pair with compatible fittings and accessories.

To start a run of duct, mount a flange to equipment. Flanges also create a secure joint between sections of duct—attach a flange to each piece. Also known as angle rings.

Duct Flanges


With Mounting Holes	With Mounting Holes

Mount flanges to air handlers and HVAC equipment to start a run of duct. They also create a secure joint between sections of duct—attach a flange to each piece. Also known as angle rings.

With Mounting Holes—Ready to install, these flanges secure with screws.

PVC—Withstand chemicals that would eat away at most metal duct. It’s often used in systems that exhaust corrosive gases, vapors, and fumes.
