Southwark Metal 142_8IN Duct Storm Collar 8 Inch

Product Description

The SOUTHWARK METAL 142_8IN is an 8-inch sheet metal duct storm collar manufactured from hot dip galvanized steel. Storm collars are installed where a vent pipe or flue passes through a roof penetration, creating a weather-tight seal that prevents rain and moisture from entering around the pipe. This collar is a standard component in HVAC and venting installations and is typically installed by HVAC technicians or sheet metal contractors during new construction or vent system service. The hot dip galvanized finish provides corrosion resistance suited to outdoor roof-line exposure.

This storm collar is sized for 8-inch round duct or pipe applications. It is commonly used in residential and light commercial HVAC installations where B-vent, single-wall flue pipe, or round sheet metal duct exits through a roof deck. Installation follows SMACNA and ACCA sheet metal standards for duct and venting systems.

Key Features

• Hot dip galvanized steel construction for corrosion resistance at roof penetrations
• 8-inch nominal size fits standard 8-inch round duct or flue pipe
• Meets ACCA and SMACNA applicable standards for sheet metal duct work
• Storm-type collar design sheds water away from roof penetration

Compatibility

Designed as an OEM-style replacement or new-installation storm collar for 8-inch round sheet metal duct and flue venting systems in residential and light commercial applications.

Installation Notes

Storm collars are installed by HVAC technicians or sheet metal contractors as part of roof penetration venting assemblies. Shut down the associated HVAC or venting appliance before beginning work at the roof penetration. The collar should be slipped over the pipe and seated firmly against the roof flashing; sealing with an appropriate roofing sealant is standard practice. Work should comply with local mechanical codes and SMACNA duct construction standards.
