500 Stainless Steel Dual Sealing A.F.O.® Plug

The .500-20 stainless steel dual sealing A.F.O. 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 also incorporates an O-ring for venting or charging. Pressure can be vented out of a side port to remove air from a hydraulic system or safely release trapped gas. A.F.O. plugs are both removable and reuseable, providing easy access to sealed passageways. They feature a unique floating seal that self-aligns to allow for threaded holes that are not perfectly concentric with the thru-hole. And, the sealing elements resist rotation during installation, which prevents galling of the seat.
