Test Ball Plug for Pipe Testing

This Cherne test ball plug is designed for temporary pipeline testing and isolation. It fits inside pipes with an inside diameter between 2.77 in and 3.25 in. The deflated dimensions are 2.64 in diameter by 5.25 in length, allowing easy insertion. It features a tire valve air connection and a ring-and-chain tether.

Suits Gravity and Low-Pressure Lines

Plumbers and contractors performing leak tests on gravity sewers or low-pressure drains will find this plug suitable. It is not intended for high-pressure applications or pipes outside the stated diameter range. Users requiring a bypass connection or a different inflation method should select an alternative model.

Critical Sizing: 2.77 in to 3.25 in Pipe ID

The single specification that determines fit is the pipe inside diameter range of 2.77 in minimum to 3.25 in maximum. The deflated plug diameter of 2.64 in must pass through the pipe opening before inflation. Verify the exact pipe ID before purchase to ensure a proper seal.

Questions about this item

How much air pressure is needed to keep the 2.64 in deflated diameter plug inflated during long pipe tests?

The plug uses a tire-valve air connection; inflate until it seals against the pipe wall between 2.77 in and 3.25 in inside diameter.

What tools or fittings are required to attach the air hose to the tire-valve connection on this 270032 model?

A standard tyre inflator or compressor chuck that fits a Schrader valve is all that is needed.

Will the 5.25 in deflated length plug fit inside a 3 in nominal pipe that has heavy corrosion buildup?

The plug seals pipes with an inside diameter from 2.77 in to 3.25 in; heavy corrosion that reduces the bore below 2.77 in will prevent a seal.
