Product identity

The Cherne 274208 is a 20 ft rubber air hose extension with a 3/16 in inner diameter, designed for plumbing professionals who need to reach test plugs up to 15 in during drain inspections. It connects to compatible inflation equipment to extend the working distance from the control source.

Thermals noise power

This passive rubber hose generates no heat, noise or electrical draw during normal use. Performance depends on the pressure supplied by the inflation device and the condition of the connected fittings. The hose material withstands typical job-site temperatures without degrading.

Bundled accessories software

Included inflation adapters allow direct connection to standard test plugs, removing the need to source separate couplings. The 20 ft length reduces the number of joints in a single run, which cuts potential leak points and speeds up setup on larger diameter pipe tests.

Questions about this item

How do I attach the 240 in air hose extension to my Cherne plug, and what step is often missed?

Connect the included inflation adapters to both the plug and hose, then tighten the clamps securely; the step often missed is verifying the 3/16 in ID matches the plug port before pressurising.

What maintenance or replacement will the rubber hose need over time?

Inspect the 20 ft rubber hose for cracks, abrasion or soft spots before each use; replace the entire extension if the material shows degradation or the adapters no longer seal.

What is the first limit reached when using this extension continuously on a 15 in plug?

The 15 in plug diameter rating is the primary limit; exceeding it risks seal failure before hose pressure or length becomes an issue.
