Dual Sealing A.F.O. Plug

The Dual Sealing A.F.O. (Axial Force Only) Plug offers a leaktight, metal to metal seal for high pressure applications and also incorporates an O-ring with backup rings for venting or charging. Pressure can be vented out of a side port to remove air from a hydraulic system or safely release trapped high pressure gas.

PDS 177 (2020-06) - Dual Sealing AFO Plug-1

With two backup rings, the Dual Sealing A.F.O. can handle high pressure from either end while in the open position. Machined from materials compliant with NACE specification MR0175, the plug can easily handle a wide range of aggressive wellbore fluids.

Dual Sealing A.F.O. Plugs are designed to be both removable and reusable, featuring 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. Incorporating threaded retention, Dual Sealing A.F.O. Plugs only impart axial force on the housing, allowing for minimal wall thickness.
