45° Configuration for Controlled Line Routing
The main advantage of the FS6802 is its 45-degree configuration.
A 45° connection can be useful when a hydraulic line needs to change direction but a 90° elbow would create too sharp a turn or take up unnecessary space.
The fitting can help:
- Redirect hydraulic hoses and tubing
- Improve line routing around equipment
- Reduce unnecessary hose bending
- Create cleaner hydraulic assemblies
- Connect ORFS and ORB components in compact layouts
- Provide better clearance around valves, manifolds, and machine components
This makes the FS6802 a useful choice for installations where connection angle matters.
Male ORFS Connection
One end of the FS6802 uses a Male O-Ring Face Seal (ORFS) connection.
ORFS fittings use an elastomeric O-ring positioned at the face of the connection to create the sealing interface. This design is widely used in hydraulic applications where reliable sealing and resistance to vibration and pressure cycling are important.
The ORFS end should be matched with the correct compatible ORFS component and inspected for damage or contamination before assembly.
Male ORB Connection
The opposite side uses a Male O-Ring Boss (ORB) connection with straight threads.
ORB connections seal using an O-ring against the compatible port rather than relying solely on the threads for sealing. This provides a dependable connection for hydraulic equipment when the correct port, thread size, and O-ring are used.
The FS6802 therefore allows an ORFS hydraulic line to connect directly to an ORB port while changing the line direction by 45 degrees.
Forged Carbon Steel Construction
FS6802 is specified with carbon steel construction and forged shaping. A trivalent zinc finish provides additional surface protection against corrosion in demanding hydraulic environments.
This makes the fitting suitable for equipment where hydraulic components may experience vibration, mechanical loading, pressure cycling, and continuous operation.
ORFS + ORB Sealing Combination
FS6802 combines two different O-ring-based sealing arrangements in one fitting:
Male ORFS: O-ring face seal
Male ORB: O-ring boss straight-thread seal
This combination can be particularly useful when hydraulic equipment contains both ORFS and ORB ports.
Instead of using multiple adapters to transition between the two connection styles, FS6802 provides the required connection types in a single 45° fitting.
Why Choose a 45° ORFS to ORB Elbow?
The 45° angle gives installers another routing option between a straight fitting and a sharper 90° turn.
It is especially useful where the hydraulic line needs to move gradually away from a port or equipment component.
FS6802 can help with:
- Tight machine layouts
- Hydraulic manifold connections
- Hose routing around equipment
- Pump and valve connections
- Hydraulic cylinder plumbing
- Mobile equipment installations
- Industrial fluid-power systems
Where FS6802 Is Used
These ORFS to ORB 45° hydraulic elbows can be used in a variety of hydraulic applications, including:
- Construction equipment
- Agricultural machinery
- Mobile hydraulics
- Industrial hydraulic systems
- Hydraulic power units
- Pumps and valves
- Hydraulic manifolds
- Heavy equipment
- OEM hydraulic assemblies
- Hydraulic hose assemblies
- Fluid power equipment
The 45° design is particularly useful when installation space or hose routing makes a straight connection inconvenient.

Built for Hydraulic Line Routing
Not every hydraulic connection needs a 90° turn. In many machines, a 45° angle provides the clearance needed to route a hose or tube without creating an unnecessary bend.
The FS6802 ORFS × ORB 45° Elbow gives hydraulic installers that additional routing option while also providing two common O-ring-based connection systems in one fitting.
This makes it a practical component for hydraulic assemblies where connection compatibility, sealing, angle, and available installation space all need to be considered.
Choose Gear House Hydraulics
Gear House Hydraulics offers FS6802 configurations for hydraulic systems requiring a Male ORFS to Male ORB 45° connection.
Before selecting your fitting, verify both connection sizes, ORFS and ORB port compatibility, hose or tubing requirements, and the pressure requirements of the complete hydraulic assembly.
Selecting the correct size and sealing configuration helps ensure a proper fit and dependable hydraulic performance.
Frequently Asked Questions
What is an FS6802 fitting?
FS6802 is a 45° hydraulic elbow that connects a Male ORFS connection to a Male ORB connection.
What does FS6802 connect?
It connects Male ORFS × Male ORB in a 45° configuration.
Is the FS6802 adjustable?
No. FS6802 is a standard 45° elbow. It should not be confused with adjustable ORB stud fittings such as FS6801 or FS6809.
What is the benefit of the 45° angle?
The 45° configuration helps redirect hydraulic lines while providing a less aggressive change in direction than a 90° elbow.
What material is FS6802 made from?
FS6802 is specified as carbon steel with forged construction.
What plating does FS6802 have?
The fitting uses a trivalent zinc protective finish.
What type of O-ring is used?
The standard O-ring material is NBR / Buna-N. Viton is available for some configurations upon request.
What sizes are available?
The FS6802 series covers sizes from 1/4" to 1-1/2", with multiple equal and reducing combinations.
Can FS6802 be used for high-pressure hydraulics?
Yes, it is designed as a steel hydraulic fitting for demanding applications. However, the actual allowable working pressure should be confirmed for the specific fitting size and complete hydraulic assembly.
Where can FS6802 be used?
It is suitable for mobile hydraulics, construction and agricultural machinery, industrial hydraulic systems, hydraulic manifolds, pumps, valves, and hydraulic hose assemblies.
