1-1/2 in pipe plug with wing nut

The Cherne 273318 is a mechanical pipe plug designed to seal 1 1/2 in pipes during pressure testing or maintenance. It fits pipes with an inside diameter between 1.44 in and 1.65 in and stands 2.56 in tall. The unit uses a wing nut to expand a stainless steel plate against the pipe wall. It is built for temporary isolation in plumbing and HVAC systems.

Suits test pressures up to 2 psi air

This plug works for low-pressure testing where air pressure does not exceed 2 psi or water head does not exceed 5 ft. It is not intended for high-pressure pipelines, permanent installations, or pipes outside the 1.44–1.65 in inside diameter range. Buyers needing bypass connections or padlock security should select a different model.

Expands to seal 1.44–1.65 in inside diameter

The single specification that determines fit is the pipe inside diameter range of 1.44 in to 1.65 in. The wing nut expands the stainless steel plate to contact the pipe wall within this window. If the pipe ID falls outside these limits, the plug will not seal.

Questions about this item

How do I install the Cherne 273318 pipe plug and what step is often missed?

Insert the plug into a 1 1/2 in pipe with an inside diameter between 1.44 in and 1.65 in, then tighten the stainless-steel wing nut until the plug seals; the step often missed is confirming the pipe ID falls within that range before installation.

What maintenance or replacement will the Cherne 273318 pipe plug need later?

Inspect the stainless-steel plate and handle for corrosion or deformation after each use; replace the plug if the sealing surface shows cracks or the wing nut threads no longer hold pressure.

What limit appears first on the Cherne 273318 pipe plug during sustained use?

The maximum back-pressure rating is reached first: 2 psi for air tests or 5 ft of head for water tests; exceeding either limit can cause the plug to unseat.
