The Lee Company has produced expansion plugs since 1948, initially for the aircraft industry. Oil and gas became our second market shortly after that. Machines intended for downhole operations have unexpected commonalities with the aerospace industry. They must function in constrained environments and under extreme temperature, pressure, and vibration. Any failures can turn into unplanned downtime that costs millions of dollars a minute.
Unlike other designs that rely on threads, O-rings, or sealants, the Lee Plug® forms a leak-tight metal-to-metal seal using the principle of controlled expansion. We continued to innovate, meeting the unique challenges that inform the design of downhole oil tools and created new products from new materials to perform under extreme pressure.
Our lineup of plugs now features NACE-compliant designs that withstand extreme temperatures and pressures. We’ve also created removable and reusable plugs rated for pressures of up to 56,000 psi. Each new shipment of plugs is manufactured under a benchmark quality system and has exacting requirements for acceptance to ensure performance for a product that serves a function as a single point of failure. As a result, we guarantee the best designs and the best quality products to serve the most demanding industry on the planet when failure isn’t an option.
Our standard product offering usually contains a plug the size and proof pressure that a customer needs. This includes evolved configurations of our original expansion plug with different material, installation, and retention options. With that said, we’re more than happy to create new designs on request. Each of our customers is unique – and they often need unique plugs. Over half of the work we perform at The Lee Company is customized to meet the needs of a specific application. So whether your solution is off-the-shelf or one-of-a-kind, you can rest assured knowing that Lee products always adhere to exacting standards for quality and performance.
