6 in Mechanical Pipe Plug
The Cherne 271578 is a galvanised steel mechanical pipe plug designed to seal 6 in pipes with an inside diameter between 5.62 in and 6.4 in. It provides a temporary blockage for testing or maintenance on drain and sewer lines. The unit has an overall height of 3.19 in and includes no water fill port or hose.
For drain testing up to 2 ft of water head
This plug suits contractors and maintenance crews who need a reusable mechanical seal for 6 in pipe IDs within the stated range. It is not for applications requiring higher back-pressure resistance than 1 psi air or 2 ft of water head, nor for pipes outside the 5.62 in to 6.4 in inside diameter window.
Hand-tightened mechanical expansion
Installation is performed by inserting the plug into the pipe and tightening the mechanism by hand until the galvanised steel plates expand against the pipe wall. The most common issue is insufficient tightening, which allows the plug to slip under pressure; always verify the seal before applying the maximum rated back pressure.

Questions about this item
What pipe inside diameter range does the 271578 mechanical plug seal?
The plug seals pipes with an inside diameter between 5.62 in and 6.4 in, matching the 6 in nominal pipe size.
Will the galvanized steel handle and plate resist corrosion when used with older cast iron drainage systems?
Yes, the galvanized steel handle and plate provide corrosion resistance compatible with cast iron and other common drainage materials.
How can I confirm the plug is holding after installation without a bypass connection?
Pressurize the line to no more than 1 psi air or 2 ft of water head; the plug should remain seated with no visible leakage past the 3.19 in height profile.
