FS6801 SAE ORFS Male to SAE ORB Male 90° Elbow | Adjustable Stud Elbow

The FS6801 SAE ORFS Male to SAE ORB Male 90° Elbow provides a compact way to connect an ORFS hydraulic port to an ORB port while changing the line direction by 90 degrees. Its adjustable stud elbow configuration gives installers added flexibility when positioning hydraulic connections.

Built in steel and available in a broad selection of size combinations, the FS6801 is designed for hydraulic systems where connection type, routing, and installation alignment all matter.

ORFS to ORB Connection in One Fitting

The FS6801 combines two widely used hydraulic connection types in one compact adapter:

• Male SAE ORFS connection
• Male SAE ORB connection
• 90° elbow configuration
• Adjustable stud design

This makes the fitting useful when a hydraulic component uses an ORB port while the connected line or component requires an ORFS connection.

Rather than combining separate adapters to achieve the same connection arrangement, the FS6801 provides the ORFS-to-ORB transition in a dedicated 90° fitting.

90° Design for Cleaner Hydraulic Routing

The 90° configuration redirects the hydraulic line without requiring the installer to create the bend through additional hose or tubing.

This can be especially useful around valves, manifolds, cylinders, pumps, machinery frames, and other components where a straight connection would create an awkward routing path.

The compact elbow configuration helps keep hydraulic assemblies organized while providing a direct directional change.

Adjustable Stud Elbow for Easier Positioning

The FS6801 is designed as an adjustable stud elbow, giving installers more flexibility when setting the final orientation of the fitting.

This is valuable when the connected hydraulic line needs to be positioned precisely after the ORB connection is engaged. Correct orientation can help improve routing and reduce unnecessary stress on hoses, tubes, and connected components.

For installations with limited access or tight equipment layouts, adjustable hydraulic fittings can make the assembly process considerably easier.

ORFS O-Ring Face Seal Connection

The ORFS side uses a Male O-Ring Face Seal connection. ORFS fittings use an O-ring at the fitting face to create the sealing interface when properly assembled with the matching connection.

This design is commonly selected for hydraulic systems where reliable sealing and reduced leakage are important.

The FS6801 combines the ORFS sealing configuration with an ORB connection on the opposite side, allowing the fitting to bridge two hydraulic connection systems.

ORB O-Ring Connection

The opposite side uses a Male O-Ring connection for an ORB port.

ORB connections use an O-ring to provide the sealing interface against the mating port. Proper thread size, O-ring condition, port compatibility, and installation are important for achieving the intended seal.

With ORFS on one side and ORB on the other, the FS6801 provides a practical connection solution for mixed hydraulic systems.

Steel Construction

The FS6801 collection is listed by Gear House Hydraulics in steel. Individual FS6801 product listings confirm steel material along with the 90° elbow configuration.

Steel construction makes the fitting suitable for demanding hydraulic equipment where a strong connection is required.

SAE 520220 Compliance

Individual FS6801 product listings identify SAE 520220 as the compliance specification for the fitting.

This gives buyers an additional specification to verify when matching the fitting to an existing hydraulic assembly or equipment requirement.

Better Routing Around Tight Equipment

Hydraulic connections often have to fit around existing equipment rather than follow a perfectly straight path.

A 90° adjustable stud elbow can make that routing easier by combining directional change with connection positioning. The FS6801 can help reduce the need for additional adapters or forced hose bends when an ORFS-to-ORB connection must turn around equipment.

This makes it a practical choice for compact hydraulic assemblies where clean routing matters.

Choosing the Correct FS6801

Before ordering, verify both connection sizes and types.

The first size in the FS6801 part number corresponds to the Male ORFS side, while the second identifies the Male ORB side.

For example:

FS6801-06-06

• Male ORFS: 06
• Male ORB: 06
• 90° adjustable stud elbow

The individual -06-06 product is listed with an 11/16-16 Male ORFS thread and a 9/16-18 Male ORB thread.

For reducing configurations, confirm both nominal sizes before ordering to ensure the fitting matches the hydraulic components being connected.

Connection Details Matter

ORFS and ORB should not be treated as the same connection type.

The ORFS side seals at the fitting face, while the ORB side uses an O-ring connection against the mating port. Matching the correct thread size and sealing configuration is essential for proper installation.

Before installation, inspect the mating ports, verify the required O-rings and sealing surfaces, and follow the appropriate assembly procedure for the hydraulic connection.

Gear House Hydraulics FS6801

Gear House Hydraulics offers the FS6801 SAE ORFS Male to SAE ORB Male 90° Adjustable Stud Elbow in a wide selection of sizes.

The collection is listed in steel, with options covering equal and reducing ORFS-to-ORB combinations. Individual products confirm the 90° shape, Male O-Ring Face Seal connection, Male O-Ring connection, and SAE 520220 compliance.

For hydraulic systems that require both mixed connection types and a 90° directional change, the FS6801 provides those functions in one fitting.

Order FS6801 ORFS to ORB 90° Elbow

When your hydraulic assembly needs a Male ORFS to Male ORB connection at 90°, the FS6801 provides a compact and adjustable solution.

Select the correct ORFS and ORB sizes for your application, verify the mating connections, and ensure the fitting is appropriate for the operating requirements of the complete hydraulic system.

FAQs
