Test Ball Plug for 2-inch pipe

The Cherne 270024 is a pneumatic test plug designed to seal pipes with an inside diameter between 1.9 in and 2.25 in. It suits plumbing professionals and maintenance crews who need a reliable temporary block for pressure testing drain lines. The unit inflates through a standard tire valve using compressed air.

Thermals noise and power draw

This mechanical plug has no electrical components, motor or fan, so it produces no heat, noise or power draw during use. Sealing performance depends only on correct inflation pressure and the condition of the pipe interior. No external energy source is required beyond the air supply used to inflate it.

Build quality and daily implications

The body is made from HAWA material with a textured surface and a deflated diameter of 1.77 in and length of 2.84 in for easy insertion. A tether ring and chain stay attached to the head for secure handling and retrieval. The male tire-valve connection works with common inflation tools, and the plug contains no bypass fitting.

Questions about this item

How do I install the Cherne 270024 test ball plug and what step do people get wrong?

Insert the deflated plug (1.77 in diameter, 2.84 in length) into a pipe with an inside diameter between 1.9 in and 2.25 in, then inflate through the tire valve; the common error is over-inflating beyond the pipe's rated pressure.

What maintenance or replacement will the Cherne 270024 test ball plug need later?

Inspect the HAWA rubber body and the ring-and-chain tether for cuts, abrasion or corrosion before each use; replace the plug if the surface texture is worn or the chain links show rust.

What limit shows up first on the Cherne 270024 test ball plug under sustained use?

The maximum pipe inside diameter of 2.25 in is the first constraint; the plug cannot seal pipes larger than this size regardless of inflation pressure.
