MME Grout Plugs (also known as Margo plugs or packers) are rugged, heavy-duty mechanical grout packers designed to accommodate difficult site conditions, provide safe and effective control of high-volume water flows, and handle various pressure grouting applications.

MME Grout Plugs are available in a range of sizes to fit common drill hole sizes from 1-1/4" up to 3". Overall length ranges from 12" to 72". Each packer consists of an internal pipe fabricated from Schedule 80 steel, threaded along the exterior to accommodate a compression nut that tightens to compress the rubber sleeves via an external compression pipe.

Each packer is supplied with three (3) compression rubber sleeves (except 12" packers, which have two (2) rubber sleeves), providing reliable sealing performance for most site and grouting conditions.

Custom setups are available. We can supply suitable low or high-pressure ball valves and connection fittings upon request to suit your specific grouting equipment and application needs.  If you are looking for custom setups and/or larger quantities, please contact us directly for a quote.
