This thread-retained plug is designed to apply axial force only on the installation hole, making it ideal for sealing holes with thin walls. This NACE-compliant solution uses a metal-to-metal seal for high-pressure applications and incorporates an O-ring for venting or charging. Pressure can be vented from a side port to remove air from a hydraulic system or safely release trapped gas. A.F.O. plugs are removable and reusable, providing easy access to sealed passageways.
