This R.F.O. plug is designed to apply radial force only on an installation hole. This plug can be used to seal openings in thin shells as well as fragile materials. It is engineered to fit into passages without the need for a support shoulder and there is no downward pressure during installation. The R.F.O. plug is installed using The Lee Companyās hydraulic installation tool. Sizes range from 0.156 to 0.875 inches.
