Oatey che-271535 Expandable Test Plug 3 Inch

Product Description

The OATEY che-271535 is a 3-inch expandable test plug designed for low-pressure blocking applications and open-ended pipe sealing. Part of the Cherne Econ-O-Grip line, this plug installs in the end of a pipe to create a temporary or semi-permanent seal. It also functions as a dust and moisture cover to protect open pipe ends during construction or service intervals. Plumbers and drain-waste-vent installers use this type of plug during rough-in inspections and pipeline pressure verification. The design accommodates standard 3-inch pipe ends without requiring special tools for basic installations.

This plug is suited for residential and light commercial plumbing applications where low-pressure test conditions apply. Typical use cases include capping a 3-inch DWV line during rough-in, blocking an open stub-out during construction, or protecting an unused pipe opening from debris and moisture intrusion. It is not intended for high-pressure testing scenarios.

Installation Notes

Installation is performed by licensed plumbers or qualified tradespeople working on DWV or low-pressure piping systems. Ensure the pipe end is clean and free of debris before inserting the plug to achieve a proper seal. This plug is intended for low-pressure applications only — do not exceed the rated pressure limit. Follow local plumbing codes, including applicable IPC requirements, when using test plugs during rough-in inspections.
