Oatey che-271543 Expandable Test Plug 4 Inch

Product Description

The OATEY che-271543 is a 4-inch expandable test plug designed for low-pressure blocking applications in drain, waste, and vent piping systems. Manufactured under the Cherne by Oatey line, this Econ-O-Grip style plug mechanically expands to form a secure seal inside the pipe bore. It blocks flow, holds pressure during low-pressure testing, and can serve as a dust and moisture cover on open-ended pipe ends. Licensed plumbers and pipefitters routinely use expandable plugs like this one during rough-in inspection, pressure testing, and system commissioning. The plug weighs 0.7 pounds and is built for straightforward field use.

This plug is suited for 4-inch pipe used in residential and light commercial plumbing installations. Typical applications include sealing open pipe ends during construction to prevent debris, dust, and moisture intrusion, as well as blocking lines during low-pressure leak testing. It is appropriate for drain, waste, and vent lines where a temporary or semi-permanent mechanical plug is needed at a pipe terminus or open stub-out.

Key Features

• Expandable design seats securely inside 4-inch pipe bore without threading or adhesive
• Rated for low-pressure blocking applications in DWV piping systems
• Functions as a dust and moisture cover on open-ended pipe ends
• Lightweight at 0.7 pounds for easy handling and transport on the job
• Cost-effective option for temporary or inspection-phase plugging needs

Compatibility

Designed as an OEM-style expandable plug for 4-inch drain, waste, and vent pipe applications in residential and light commercial plumbing systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing code requirements. Verify that the pipeline is depressurized and drained before inserting or removing the plug. Do not exceed the low-pressure rating of this plug; it is not intended for high-pressure line testing. Inspect the expansion mechanism for wear or damage before each use to ensure a reliable seal.
