 Connection Method

  • The ORFS Lock Nut is threaded onto the body of an ORFS male fitting.

  • It is used to tightly fasten the male fitting into an ORFS female port with a flat-face seal.

  • While the lock nut itself does not create the seal, it ensures that the sealing surfaces remain tightly connected and resistant to movement.

  • Commonly used in high-vibration or mobile hydraulic systems.
