The OATEY ECONOTP3 is a 3-inch Econ-O-Grip pipe plug designed for low-pressure blocking applications and sealing open-ended pipe. This mechanical plug provides a cost-effective, reliable seal in drain, waste, and vent piping during testing, inspection, or temporary isolation work. Its grip-style design allows for secure installation and removal without specialized tooling. Plumbers and pipe trades installers use this plug when a dependable, reusable mechanical stop is needed on exposed pipe ends during rough-in, pressure testing, or service work.
This plug is suited for residential and light commercial plumbing applications where low-pressure pipe blocking is required. Typical scenarios include plugging open pipe ends during DWV rough-in, isolating sections of pipe for inspection, or preventing debris entry during construction. The 3-inch size fits standard 3-inch nominal pipe openings commonly found in drain and vent systems.
Designed as an OEM-style replacement and standard-fit plug for 3-inch nominal pipe in residential and light commercial drain, waste, and vent systems.
Installation is performed by licensed plumbers or qualified pipe trades professionals. Before installing or removing this plug in an active system, shut off any upstream flow and verify the line is depressurized. This plug is rated for low-pressure applications only and should not be used where line pressure exceeds the product rating. Follow applicable local plumbing codes and IPC guidelines when using pipe plugs for pressure testing or isolation.
