The IPEX 112004w is a 4-inch white PVC termination screen designed for direct-vent and concentric-vent HVAC applications. It pushes to fit into a standard PVC hub, making installation straightforward without adhesives or special tools. The screen protects flue termination and combustion-air intake openings from debris, pests, and weather intrusion. Licensed HVAC technicians installing high-efficiency furnaces and boilers rely on this type of termination fitting to meet manufacturer venting requirements and local mechanical codes. The white finish blends with typical PVC vent pipe and exterior wall aesthetics.
This termination screen is suited for residential and light commercial high-efficiency heating systems that use PVC venting. It is typically installed at exterior wall penetrations where the vent pipe exits the building. The push-fit PVC hub connection allows it to seat directly onto 4-inch PVC pipe without cement, though local code or manufacturer instructions may require solvent welding. HVAC technicians handling Category IV appliance venting will recognize this fitting as a standard component in concentric or two-pipe termination assemblies.
Designed as an OEM-style termination fitting for 4-inch PVC vent systems on residential and light commercial high-efficiency heating appliances.
Installation is performed by a licensed HVAC technician. Shut down and lock out the heating appliance before servicing any vent termination fitting. Verify that the termination location meets required clearances per the appliance manufacturer instructions and applicable mechanical codes such as the IFGC. Confirm whether local code requires solvent-welded joints even on push-fit fittings before completing the installation.
