The Series FS0306 ORFS Bulkhead Lock Nuts, made from carbon steel and manufactured per SAE 520118 standards, are designed to provide a secure and reliable connection in hydraulic systems. These lock nuts are used with O-Ring Face Seal (ORFS) fittings to ensure a leak-proof seal, particularly in bulkhead applications. Their robust carbon steel construction offers durability and strength, making them ideal for high-pressure fluid power systems. The bulkhead design allows for secure mounting through panels or walls, while the lock nut feature prevents loosening due to vibrations or pressure fluctuations. These ORFS bulkhead lock nuts are an essential component for creating stable, leak-free connections in a variety of industrial and fluid power applications.
