Mechanical Locking Plug for 3 In Pipes

The Cherne 271669 is a mechanical locking plug designed to seal 3-inch nominal pipe openings. It fits internal diameters ranging from 2.8 to 3.1 inches. The plug uses a plastic and rubber construction to create a secure seal in monitoring well applications.

Suits monitoring well sealing

This plug works for technicians needing a mechanical seal that holds up to 6.5 PSI of back air pressure or 15 feet of head pressure. It is not suited for permanent installations requiring higher pressure ratings or for pipe sizes outside the stated diameter range.

Seals 2.8 to 3.1 inch internal diameters

The adjustable expansion range is the critical specification that determines fit. Verify the exact internal diameter of the pipe or well casing before purchase to ensure the plug can lock securely within the 2.8 to 3.1 inch window.

Questions about this item

How can I verify the 271669 plug is sealing correctly once installed?

Pressurise the line up to 6.5 PSI air or 15 ft of head water and confirm no pressure drop or leakage around the 2.8–3.1 in expansion range.

What comes with the mechanical locking plug and what must I source separately?

The plug ships as a complete plastic-and-rubber unit; no extra hardware is included, so supply your own wrench or installation tool if required.

Which nominal size should I select for a 3-inch monitor well?

Choose the 3 in nominal size — it covers a minimum diameter of 2.8 in and a maximum of 3.1 in for that application.
