The Lee Co. - Westbrook, CT
Manufacturer, Custom Manufacturer, Manufacturers' Rep
Manufacturer of plugs to seal drilled holes for critical applications. Over 100 million are in use on aircraft, missiles, spacecraft, machine tools, down hole oil tools, molds - anything that requires a permanent leak-proof seal. The plug is a cylindrical plug with a tapered hole part way through its center & numerous small grooves on its outside diameter. It is slipped into a reamed counterbore in the product. A tapered pin is then driven into the plug until the ends of the pin & the plug are flush with each other. Controlled expansion causes the lands & grooves of the plug to "bite" into the surrounding material forming independent seals & retaining rings. Result: a positive, reliable, leak & trouble-proof seal for both liquids & gases.
