This member of our classic Lee Plug® family is made from MP35N, a NACE-compliant nickel-cobalt alloy that provides excellent corrosion resistance for harsh-duty applications found in the oil and gas industry. Lee plugs continue to be the simplest, most successful method for sealing cross-drilled holes. Upon installation of the pin, controlled expansion causes the lands and grooves of the plug to “bite” into the surrounding material, forming independent seals and retaining rings. Sizes range from 0.093 to 0.343 inches.
