Oatey Company 43805 Mushroom Vent Cap

Product Description

The OATEY COMPANY 43805 is a mushroom-style vent cap designed to terminate plumbing drain-waste-vent (DWV) pipe runs at the roof or wall. The domed mushroom profile deflects rain, debris, and pests while allowing sewer gases and air to pass freely through the vent stack. It provides a low-profile, weather-resistant termination point that keeps the vent line open and operating correctly. Licensed plumbers and pipefitters install this fitting during new construction and re-roofing projects as a standard DWV component.

The 43805 is suited for residential and light commercial plumbing systems where a code-compliant vent termination is required. It fits over the top of a vertical vent stack pipe and is commonly installed on single-family homes, multifamily buildings, and small commercial structures. The package quantity of 12 units per case makes it practical for contractors stocking material for multiple jobs at once.

• Allows free passage of sewer gases to atmosphere while blocking backflow of weather
• Packaged 12 units per case, supporting multi-job or multi-unit project quantities

Compatibility

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local amendments. Shut off any active systems and allow the vent stack to be safely accessed before beginning roof or wall work. Secure the cap per the manufacturer fit and local code requirements to prevent wind displacement. Follow all applicable fall-protection and roof-safety protocols when working at height.
