Oatey 270040 Pneumatic Pipe Plug 4 Inch 13 Psi

Product Description

The OATEY 270040 is a pneumatic pipe plug designed for pressure testing drain, waste, and vent piping systems. It inflates to create an airtight, watertight seal inside a 4-inch pipe, allowing technicians to isolate a section of pipe and apply test pressure up to 13 psi. The plug body is made from natural rubber, which conforms to the pipe wall and maintains a reliable seal under working pressure. Plumbers and pipefitters use this tool during rough-in inspections and system commissioning to meet code-required pressure test requirements.

This plug is suited for residential and light commercial plumbing applications where 4-inch DWV pipe is being tested. It is inserted into the pipe opening, inflated via the valve stem, and pressurized to the required test level. Natural rubber construction makes it compatible with both plastic and cast iron pipe commonly found in drain and vent systems. It is manufactured domestically.

Key Features

• Inflatable pneumatic design creates a positive seal without mechanical fasteners
• Rated for 13 psi working pressure for standard DWV pressure testing
• Natural rubber body conforms to pipe interior for a leak-free seal
• Fits 4-inch nominal pipe size
• Domestic manufacture

Compatibility

Designed for use in 4-inch nominal diameter drain, waste, and vent pipe during pressure testing procedures.

Installation Notes

Installation is performed by licensed plumbers during rough-in or pre-inspection pressure testing. Before inserting the plug, confirm the pipe section is clean and free of sharp debris that could damage the rubber. Inflate to working pressure using a hand pump or compressed air source and monitor for pressure loss per local plumbing code requirements. Do not exceed the 13 psi working pressure rating.
