A.F.O. (Axial Force Only) Lee Plugs


The Lee 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 plug features a unique floating seal that self-aligns to allow for threaded holes that ar not concentric with the thru-hole. Also, the seal does not rotate during installation, preventing galling of the seat.

The two piece assembly is constructed entirely of corrosion resistant stainless steel, and requires no O-rings or sealants. The plug can be used in hard materials as well as in softer materials such as aluminum or plastics.

  • Reusable - allows easy access to sealed passageways
  • Seals to 56,000 psi
  • Usable to 600 °F
  • All CRES construction - no sealants or O-rings
  • Floating Seal Self Aligns - Prevents Galling
  • Axial force only - small boss size
  • Custom designs considered


The Dual Sealing A.F.O. Plug has all the features of the standard A.F.O. Plug, but incorporates an O-ring for venting. With this plug, pressure can be vented out of a side port to remove air from a hydraulic system or safely release trapped high pressure gas.
