A.F.O. Plug (Axial Force Only)

The A.F.O. Plug provides a leak-tight, metal to metal seal in high pressure, high temperature manifold applications. Designed to be both removable and reusable, the plugs feature a floating seal that self-aligns to allow for threaded holes that are not concentric with the through hole. As a result of the plugs' two-piece construction, the seal does not rotate during installation, thus preventing galling of the seat. Also, since all the force is contained in the axial direction, the boss diameter can be smaller compared to other designs of plug. Standard A.F.O. plugs are manufactured from corrosion resistant 303 and 15-5PH stainless steel and do not require O-rings or sealants. They are designed to withstand pressures up to 56,000 psi and temperatures to 600F, when fitted into hard materials and can be used in softer materials as well, such as aluminium or plastic. The plugs are available in sizes from .190" to .750" with UNF threads, however, depending on specific application requirements, special versions can be supplied. A.F.O. plugs have recently been supplied in Monel in sizes up to 1,325" UNF threads to withstand 15,000 psi working pressure and 22,500 psi proof pressure. A.F.O. Plugs are typically used in the offshore oil industry where applications include subsea wellhead trees, tubing hangers, completion tools, slick joints and down hole tools. A range of NACE compliant A.F.O. Plugs made from MP35N is also available. These plugs conform to the requirements of NACE MRO175 / ISO 15156 and offer exceptional resistance to corrosion and sealing performance in high pressure, high temperature applications.
