Product Description

The METAL-FAB 3CGSW18 is a single-wall straight length pipe from the Corr/Guard Small Diameter series, designed for venting applications in residential and light commercial settings. Measuring 3 inches in diameter and 18 inches in length, this pipe section serves as a core component in vented combustion appliance exhaust systems. It is installed by licensed HVAC technicians and plumbers working with gas-fired appliances that require code-compliant venting runs.
