SAE ORFS Bulkhead Locknut (Stainless Steel) - Part FS306-SS

Part Number: FS306-SS

SAE ORFS Bulkhead Locknut (Stainless Steel)

Product Overview

The Delphi Fittings Part FS306-SS is a heavy-duty locknut for securing SAE O-Ring Face Seal (ORFS) bulkhead fittings. Manufactured from high-grade 316 stainless steel, this locknut provides the essential clamping force to mount an ORFS bulkhead fitting (such as the FS27xx-SS series) firmly to a panel, bracket, or machine wall. Its material construction ensures it matches the corrosion resistance and durability of the fitting it secures, making it a critical component for any robust, panel-mounted hydraulic connection in demanding environments.

Applications

The FS306-SS locknut is an indispensable component for any ORFS bulkhead installation:

  • Used to securely mount straight, 45-degree, 90-degree, and tee-style ORFS bulkhead fittings.
  • Ensures the stability of hydraulic pass-through connections on control panels, vehicle dashboards, machine enclosures, and mounting brackets.
  • Critical for maintaining a rigid and vibration-resistant connection point in mobile and industrial hydraulic systems.
  • The 316 stainless steel construction makes it essential for installations in marine, chemical, food processing, and other corrosive environments.

Installation & Usage Guidelines

  • After inserting the ORFS bulkhead fitting through a correctly sized panel hole, thread the FS306-SS locknut onto the fitting's body.
  • Use a wrench to tighten the locknut firmly against the panel surface, creating a secure clamp.
  • It is recommended to use a second wrench on the hex of the bulkhead fitting body to prevent it from rotating while the locknut is tightened.
  • Ensure the nut is torqued sufficiently to prevent any loosening or movement of the bulkhead fitting during operation.
