In the 1950s, engineers searched for a more reliable and effective way to seal machined and cross-drilled holes in metal housings. In response, The Lee Company developed a plug designed to form a permanent, leak-tight seal without using O-rings, threads, or sealants. The Lee Plug® remains the best seller for The Lee Company, with well over 200 million plugs used in hydraulic systems. The Lee Company is the original OEM and the only qualified aerospace supplier for expansion plugs.
