Mechanical Research & Design, Inc. has been providing innovative and proven Pipe Plugs all over the world for nearly 25 years. Also called pressure test plugs, pipe stoppers, pipe bungs, line stops, or inline isolation tools, pipe plugs are a common pipeline pressure test and isolation barrier tool for both newly fabricated or existing piping systems. Mechanical Research & Design, Inc. designs and manufactures many standard, off the shelf configurations as well as custom, application specific barrier options for low, medium, and high pressures (most styles from vacuum test pressures through several thousand PSI). We supply round plugs, rectangular plugs, irregularly shaped plugs that can be used in pipelines (carbon steel, stainless steel, ductile iron, polymer, composite, ceramics, concrete, to name a few), tubing, tunnels, shafts, bores, hoses, assembled components, water intakes, and nearly any part that requires pressure or leak testing.
