Aerospace industry No.1 share plug!! The benchmark for expansion plugs representing the industry!!
The Lee Plug is the foundation of our extensive aerospace product line. Going back to the 1950s, engineers were searching for a more reliable and effective way to seal machined metal housings and cross-drilled holes. In response to this need, The Lee Company created a plug designed to form a permanent leak-proof seal without the use of O-rings, screws, or sealants. The Lee Plug remains the company's best-seller, with over 200 million plugs used in aircraft, missiles, space transportation systems, and other advanced hydraulic systems. There are various reasons why the Lee Plug continues to be a best-seller. Not only is Lee Company the original OEM and the only certified supplier of single point of failure (SPOF) technology, but our expertise in solving technical challenges, experience, innovative products, and commitment to quality set us apart from competitors. This is why The Lee Company remains the only SAE-certified provider of aerospace expansion plugs. More than half of our products are custom-made to meet specific requests, and we contribute to solving your company's challenges with flexible responses.
