Mechanical Pipe Plug 2.5 in
The Cherne 269913 is a mechanical pipe plug designed to seal pipes with a 2.5 in nominal size. It fits inside diameters between 2.3 in and 2.78 in using a rubber sealing element and galvanised steel plates. Plumbers and maintenance crews use it for temporary line stoppage during repairs or testing.
Pressure and Diameter Limits
The plug withstands a maximum back pressure of 72 psi for air and 166 ft of head for water. It only seals pipes whose inside diameter falls within the 2.3 in to 2.78 in range. Lines outside this tolerance or pressures above the rated values will not hold.
Installation and Common Issues
Tighten the mechanism by hand or with a wrench until the rubber expands firmly against the pipe wall. No hose or water fill port is included, so pressure testing requires separate equipment. Leaks usually mean the pipe diameter is outside the 2.3 in to 2.78 in range or the rubber is damaged.

Questions about this item
Which Cherne 269913 size fits my 2 1/2 in pipe?
The plug is sized for 2 1/2 in nominal pipe and seals inside diameters from 2.3 in to 2.78 in.
What does the 72 psi air rating mean when I test a line?
It is the maximum back pressure the plug will hold with air; do not exceed 72 psi during pneumatic testing.
How does the 166 ft of head water rating limit a hydrostatic test?
It caps the water-column height the plug can restrain; the test head must stay at or below 166 ft.
