218 Monel Lee Plug®

This member of our classic Lee Plug family is made from Monel, a nickel alloy that provides exceptional corrosion resistance in a variety of applications. 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 0.656 inches.
