Part Number: FS6400-SS

SAE ORFS Male x SAE ORB Male Straight Adapter (Stainless Steel)

Product Overview

The Delphi Fittings Part FS6400-SS is a high-performance straight adapter that connects two of the industry's most reliable sealing technologies: O-Ring Face Seal (ORFS) and O-Ring Boss (ORB). This fitting features a male ORFS end and a male ORB end, allowing a female ORFS swivel connection to be made to a female ORB port. Manufactured from 316-grade stainless steel, this adapter is the premier choice for creating a durable, leak-proof connection between components in corrosive, high-purity, or other demanding hydraulic systems.

Applications

The FS6400-SS adapter is critical for integrating components in high-spec hydraulic systems:

Connecting ORFS hose assemblies directly to the SAE ORB ports found on pumps, valves, cylinders, and filter housings.
Essential for plumbing in corrosive environments such as marine, offshore, and chemical processing where stainless steel is mandatory.
Allows for the use of easy-to-service, zero-clearance ORFS connections on hoses while interfacing with the industry-standard ORB component ports.
Provides a direct, one-piece connection that is more reliable and compact than using multiple adapters to achieve the same result.

Installation & Usage Guidelines

ORB End: Ensure the O-ring is correctly seated, lubricated, and undamaged. Thread into the female ORB port and tighten to the specified torque.
ORFS End: Ensure the O-ring on the flat face is clean and lubricated. Connect the female ORFS swivel nut and tighten to its specified torque.
Use a wrench on the adapter's hex body to hold it stationary while tightening the ORFS swivel nut to prevent disturbing the ORB connection.

Why Choose Delphi Fittings Part FS6400-SS?

Reliable Hybrid Connection: Securely joins two of the best O-ring based sealing systems—ORFS and ORB—for a doubly secure connection.
Superior Leak Protection: Both ends utilize O-rings, providing exceptional resistance to leaks caused by high pressure, shock, and vibration.
Maximum Corrosion Resistance: 316 stainless steel construction offers unmatched longevity in harsh environments.
Simplified Plumbing: A robust, one-piece solution for adapting between ORFS lines and ORB ports, reducing complexity and potential leak points.
Dual Standard Compliance: Meets or exceeds both SAE J1453 (ORFS) and SAE J1926-1 (ORB) standards for guaranteed compatibility.
