The Lee Company has designed a new version of it’s A.F.O. (Axial Force Only) Plug to incorporate an O-ring for additional sealing in critical oil tool applications.

According to the company, this Dual Sealing A.F.O. Plug is designed to vent air from a product when filling it with hydraulic oil or to release trapped high pressure gas, and features:

• A design to be both removable and reusable.
• A floating seal that self-aligns to allow for threaded holes that are not concentric with the through hole.
• Two-piece construction, so the seal does not rotate during installation, thus preventing galling of the seat. 
• Manufacturing from corrosion resistant 303 and 15-5 stainless steel.
• Ability to withstand pressures up to 56,000 psi and temperatures to 600°F.
