Round plug PLGM series

threadedaluminumforming

This member of our classic Lee Plug family is ideal for installation into aluminum manifolds. 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 2.5 to 8 millimeters. - Plug Diameter: 5.50 mm - Max.
