M.W. PLUG (MULTI-WORKER™)


The LansasMW™ is the most versatile and cost effective single-size plug available.

Our 4″-12″ MW’s™ are molded with “o-ring” sealing ribs and each plug is equipped with a replaceable bypass pipe.

Our 15″ – 24″ MW’s™ are stocked with either a 4″, 6″, or 8″ bypass .

For air or water testing, sewer bypass or simply stopping the flow, the MW™ offers the best value in single size plugs.

Test caps are available to convert your flow thru pipe plugs over to use in air testing applications. A PVC cap is supplied with each plug with up to a 6″ NPT by-pass.
