Oatey 271047 Long Pipe Plug 4 Inch 13 Psi

Product Description

The OATEY 271047 is a long pipe plug designed for pressure testing in drain, waste, and vent piping systems. It seals a 4-inch pipe opening and holds a working pressure of 13 psi, making it suitable for standard DWV pressure and leak-down tests. Plumbers and pipefitters install this plug to isolate sections of pipe during new construction or service work. The long-body design provides additional gripping surface inside the pipe bore for a more secure, leak-resistant seal during testing procedures.

This plug is used in residential and light commercial plumbing applications where 4-inch DWV lines require temporary closure for inspection or pressure testing. It is a domestically produced component suited for use in new rough-in work, remodel projects, and code-required pressure verification before system sign-off. A licensed plumber or journeyman typically installs this fitting during the rough-in inspection phase of a project.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Confirm the pipe bore is clean and free of debris before inserting the plug to ensure a proper seal. Do not exceed the rated 13 psi working pressure during testing. Remove the plug completely before restoring the system to service.
