Tapered plug

cylindricalthreadedmetal

The founding, flagship product from The Lee Company. It works like this: the cylindrical plug body contains a tapered hole partway through. The body is inserted into a properly reamed hole. A tapered pin is then inserted into the plug itself. This causes the plug to expand in a controlled manner. Lands and grooves on the side of the plug then bite into the sides of the hole, creating multiple metal-to-metal seals. See Installation Process Specification 203 (which applies to all Lee expansion plugs) for more information. Lee Plugs are manufactured to exacting tolerances. Every process is precisely controlled. Each lot of pins and plugs undergoes a rigorous inspection and acceptance testing. This ensures performance when any failure could be catastrophic. Standard Lee Plugs are available in multiple grades of aluminum, stainless steel, and Monel, plus titanium and MP35N. They can be purchased in diameters from 0.093 to 0.656 of an inch or metric sizes from 2.5 to 8.0 mm.
