Extension Hose for Inflatable Plugs

The Cherne 274100 is a rubber air hose extension designed to connect an inflation source to compatible pipe plugs. It suits maintenance crews and plumbers who need extra reach when testing or sealing drain lines up to 15 inches in diameter. The 10 ft length adds working distance without moving the air supply.

Replaces Shorter Factory Leads

This extension replaces the shorter hoses supplied with many Cherne plug kits when the job site layout puts the compressor or hand pump farther from the access point. The upgrade is worth it when the standard hose cannot span the trench, manhole depth or confined-space entry distance required by the specific installation.

Push-On Installation With Included Adapters

The hose slides onto the plug inflation port and the supplied inflation adapters using a friction fit; no tools or clamps are required. The most common issue is forgetting to seat the adapter fully before pressurising, which can cause the hose to blow off under pressure. Always verify a firm connection before inflating.

Questions about this item

Will the 120-inch length and 3/16-inch ID reach a 15-inch plug through a standard cleanout?

The hose extends 10 ft with a 3/16-inch ID, designed for plugs up to 15 inches, so measure your access point to confirm reach.

How do the included inflation adapters connect to the hose and the test plug?

Push each adapter onto the hose ends until seated, then thread onto the plug's inflation port; the step often missed is fully seating both barbs before pressurising.

When should the rubber hose be replaced if used for regular sewer testing?

Inspect before each use; replace the hose if the rubber shows cracks, abrasions, or soft spots, or after any test where pressure exceeded the plug rating.
