Duravent 04PC B-vent Pipe Support Collar 4 Inches

Product Description

The DURAVENT 04PC is a B-vent pipe support collar designed to secure and stabilize 4-inch double-wall B-vent pipe in vertical venting installations. The collar fits around the outside of the vent pipe and anchors to framing or structural members, maintaining proper pipe alignment throughout the vent run. It is used in Category I gas appliance venting systems, including those serving gas furnaces, boilers, and water heaters that exhaust at low positive pressure. Licensed HVAC technicians and plumbers install this component during new construction and replacement vent system projects.

This support collar is intended for use in residential and light commercial vertical B-vent installations where code requires the vent pipe to be secured at designated intervals. The 04PC is designed to work within 4-inch double-wall B-vent systems, holding the pipe in position against framing, floor joists, or structural blocking. Proper installation at required support intervals helps prevent pipe sag, joint separation, and misalignment over the life of the venting system.
