Test Ball Plug for 2-3 Inch Pipes
The Cherne 274518 is a pneumatic test ball plug designed to seal pipes with inside diameters between 1.75 and 3.25 inches. It serves plumbing professionals and maintenance crews who need a reliable temporary blockage for pressure testing or isolation tasks. The textured rubber body provides grip inside the pipe wall during inflation.
Suited for Straight Pipe Sections Only
This plug fits pipe sizes ranging from 2 to 3 inches and requires an accessible opening for insertion. It is not suitable for pipes smaller than 1.75 inches or larger than 3.25 inches inside diameter. Installations needing a bypass port for flow-through testing should select a different model.
Deflated Diameter of 1.58 Inches
The plug collapses to a 1.58 inch diameter and extends 19.44 inches in length when deflated, allowing it to pass through cleanouts and bends before inflation. A tank-valve connection accepts standard air sources for pressure activation. The head includes a handle and strap for secure placement and retrieval.

Questions about this item
What comes with the Cherne 274518 pneumatic test ball plug and what must be purchased separately?
The plug includes a built-in handle and strap for tethering. An inflation hose with a tank-valve fitting and a pressure gauge are not included and must be supplied by the user.
Which pipe sizes does the Cherne 274518 model 274518 cover?
It seals pipes with an inside diameter from 1.75 in up to 3.25 in, corresponding to nominal 2 in to 3 in pipe sizes.
What does the 1.58 in deflated diameter mean when the plug is inserted into a 2 in pipe?
The plug collapses to 1.58 in wide and 19.44 in long, so it slides easily into a 2 in pipe before inflation creates the seal.
