Tapco 972-201K Polypropylene B-vent Sleeve

Product Description

The TAPCO 972-201K is a polypropylene B-vent sleeve used in venting system installations to provide a secure transition or protective fitting at vent pipe penetrations and connections. Polypropylene construction offers resistance to condensate and flue gas byproducts common in gas appliance venting. This sleeve is a standard component installed by HVAC technicians and plumbers working on Type B gas vent systems in residential and light commercial applications.

This sleeve is suited for use in Type B double-wall gas vent systems, typically found on natural gas and propane furnaces, boilers, and water heaters. It is installed at points where the vent pipe passes through a wall, ceiling, or structural assembly, providing a finished and code-appropriate fit at the penetration. HVAC and mechanical contractors working on venting rough-in or replacement projects will encounter this fitting type regularly.

Key Features

• Polypropylene construction resists moisture and flue gas condensate
• Designed for Type B gas vent system applications

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and local mechanical code requirements, including IFGC guidelines for gas vent systems. Shut off the gas supply and allow the appliance and vent system to cool completely before beginning any venting work. Ensure the sleeve is fully seated and that all vent joints meet clearance-to-combustibles requirements per the vent system manufacturer and applicable code.
