Locking Plug for 1–1.25 In Pipes
The Cherne 271648 is a mechanical locking plug built for pipe diameters between one and 1.25 inches nominal size. It fits monitor wells and drain openings where a secure, temporary seal is required during testing or maintenance work.
Pressure Capacity and Limits
The plug withstands up to 6.5 PSI of back air pressure and holds against 15 ft of head pressure. It seals openings from a minimum of 1 in to a maximum of 1.38 in, providing headroom within that range but cannot be used on larger diameters or higher-pressure systems.
Upgrade from Inflatable or Single-Size Plugs
This mechanical design replaces inflatable plugs that need a pump and single-size plugs that only fit one diameter. The jump is worthwhile when you need a reusable, tool-free seal across the 1–1.25 in range without carrying multiple sizes or an inflation source.

Questions about this item
Will the 1-1.25 In mechanical locking plug fit the existing 1 In monitor well pipe I plan to keep?
The plug fits nominal sizes from 1 to 1.25 In with a minimum diameter of 1 In and a maximum diameter of 1.38 In, so it will seal your 1 In pipe.
How can I verify the 271648 plug is sealing correctly once installed?
The plug is rated for a maximum back air pressure of 6.5 PSI and a maximum back pressure of 15 ft of head; holding those pressures without leakage confirms it is working.
Does the Cherne 271648 package include any tools or lubricant, or must I buy them separately?
The product is supplied as the mechanical locking plug only, constructed from plastic and rubber; any installation tools or lubricant must be purchased separately.
