threadedaluminumfor automotive applications

Lee R.F.O. Plugs are designed to seal holes in thin walls or fragile materials. Designed to be easily removable, these plugs do not require a support shoulder and the installation system ensures that no downward pressure is applied to the product. Lee R.F.O. Plugs are available in aluminum and can be found in standard diameters ranging from 0.156 to 0.875 of an inch. The .093 inch high strength expansion plug is constructed of 15-5PH CRES and designed to seal passageways in high strength, high hardness materials such as Titanium and Inconel. Its high strength and unique geometery, coupled with the proven reliability of our Lee Plug expansion prinicipal, are what give it a proof pressure rating of 32,000 psi (221 Mpa). Each plug is also available in an oversize configuration that is 0.010 of an inch larger in diameter for manifolds that require reworked installation holes.
