Pneumatic pipe plug with a 2.38 in deflated diameter and 5.81 in deflated length seals 2 in pipes using a tire-valve air connection

  • Product typeDrain Components
  • Main materialHAWA
  • Pneumatic operation seals pipes without manual effort using tire-valve air connection
  • Textured body surface resists slippage during inflation and deflation cycles
  • Compact deflated diameter of 2.38 in fits through tight access points
  • Short 5.81 in deflated length allows insertion into shallow trap assemblies
  • Designed for 2 in pipe size to match standard drain-component specifications

Pneumatic pipe plug for 2 in lines

The Cherne 271705 is a pneumatic pipe plug designed to seal 2 inch pipes during testing or maintenance. It inflates through a male tire-valve connection and has a deflated diameter of 2.38 in for insertion. The textured body surface helps the plug grip the pipe wall. This tool suits plumbers and contractors who need a reliable temporary blockage.

Fits 2 in pipe ID only

This plug works only where the pipe inside diameter matches the 2 in size rating. It has no bypass connection, so the line must be fully isolated while the plug is in place. Buyers who need a bypass for flow diversion or a plug for a different pipe diameter should look at other models. The 1/8 in air connection also requires a compatible inflation hose.

Deflated diameter 2.38 in

The deflated diameter of 2.38 in determines whether the plug can enter the pipe before inflation. If the pipe interior is smaller than this figure, the plug will not pass through the opening. Always verify the pipe inside diameter against this measurement before purchase. The deflated length of 5.81 in also affects access through fittings.

Questions about this item

How do I install the Cherne 271705 pneumatic plug and what step is commonly missed?

Insert the deflated plug (2.38 in diameter, 5.81 in length) into the 2 in pipe, then inflate via the 1/8 in male tire valve; the step often missed is verifying the plug is centered and fully inflated before applying back-pressure.

What maintenance or replacement will the Cherne 271705 plug need over time?

Inspect the textured HAWA body for cuts, abrasion, or cracking before each use; replace the unit if the rubber shows degradation or the tire-valve connection no longer holds air pressure.

What limit appears first when the Cherne 271705 plug is used under sustained pressure?

The plug is rated for 2 in maximum pipe size with no bypass; the practical limit is the HAWA material's ability to maintain seal integrity under continuous back-pressure without a relief path.
