Mechanical Pipe Plug with Bypass

The Cherne 272949 is a mechanical pipe plug designed for temporary flow stoppage or testing in six-inch pipelines. It serves plumbers and maintenance crews who need a reusable internal seal with an integrated bypass for fluid diversion or pressure monitoring.

Capacity and headroom

The plug fits pipe inside diameters from 5.7 to 6.3 inches and withstands up to 10 psi air back pressure or 23 feet of water head. It runs out of sealing range beyond those diameters or when back pressure exceeds the stated limits.

Build and daily use

An aluminum sealing plate and zinc-plated steel handle resist corrosion during repeated insertion and removal. The 3/4-inch male NPT bypass port accepts standard fittings for hose or gauge attachment, while the 9.7-inch overall height provides reach inside the pipe without excessive protrusion.

Questions about this item

Will the 6.3 in maximum pipe inside diameter fit the 6 in cast-iron drain I already have?

Yes, the plug seals inside pipes from 5.7 in to 6.3 in, so a 6 in cast-iron line falls within range.

How can I verify the 10 psi air back-pressure rating is holding after installation?

Pressurise the line to the rated 10 psi air maximum and watch the gauge; a steady reading confirms the seal is working.

Does the box include the water-fill hose for the bypass, or must I supply it?

The water fill port is included but the hose is not; you will need to provide your own hose for the 3/4 in NPT male bypass connection.
