Cylindrical plug Lee A.F.O.®

threadedstainless steelvent

Unlike other plugs in our product family, A.F.O. Plugs are both removable and reusable due to their threaded design, allowing technicians easy access to sealed passageways. Despite this, the A.F.O. Plug still seals up to 56,000 psi. Each plug features a floating seal that self-aligns, allowing for threaded holes that aren’t concentric with the through-hole. Lastly, the A.F.O. designation means no radial force is applied during installation, making this component suitable for thinner-walled housings. See Installation Process Specification P1013 (which applies to all A.F.O. Plugs) for more information. A.F.O. Plugs are made from stainless steel and are available in standard diameters ranging from 0.190 to 0.625 of an inch. The .190 Stainless Steel A.F.O.® Plug is a thread retained plug designed to apply Axial Force Only on the installation hole, allowing for minimal wall thickness. It utilizes a metal to metal seal for high pressure applications and is both removable and reuseable, providing easy access to sealed passageways. A.F.O. plugs feature a unique floating seal that self-aligns to allow for threaded holes that are not perfectly concentric with the thru-hole. Also, the sealing elements resist rotation during installation, which prevents galling of the seat. High proof pressures, up to 56,000 psi (386 MPa). Reuseable, allowing easy access to sealed passageways. Floating seal self-aligns, prevents galling.
