Venting plug takes O-ring onboard

A new version of the AFO (axial force only) plug incorporates an O-ring for additional sealing in special oil tool applications.
Now available from miniature component specialists Lee Products is a new version of its AFO (axial force only) plug that incorporates an O-ring for additional sealing in special oil tool applications.
The plug is designed to vent air from a product when filling it with hydraulic oil or to release trapped high pressure gas from an activated down-hole pyrotechnic tool when brought to the surface.
Secondary retention of the plug in the manifold is provided by a circlip which prevents the plug from being removed completely from the manifold, thus safely protecting the operator during the gas venting process.
AFO plugs are designed to be both removable and reusable and are ideal for high pressure/high temperature manifold applications.
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 plug's 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 with other designs of plug.
Standard AFO plugs are manufactured from corrosion resistant 303 and 15-5 stainless steel and are designed to withstand pressures up to 4100bar and temperatures to 315C.
NACE compliant models are also available made from MP35N.
