A Run Tee Designed for Better Alignment
The FS6804 ORFS ORB Run Tee is useful when a hydraulic circuit needs a straight-through connection plus an additional adjustable outlet.
Instead of forcing the connected line into a fixed position, the adjustable ORB stud allows the center port to be oriented as needed during installation. This can make a noticeable difference when working around pumps, valves, manifolds, machine frames, and other components with limited routing space.
The two ORFS connections remain on the main run while the adjustable ORB connection provides the additional connection point.
Three Connection Points in One Fitting
FS6804 combines three hydraulic connection points:
Male ORFS → Male Adjustable ORB → Male ORFS
The two ORFS ends are designed for compatible O-Ring Face Seal connections, while the center ORB stud uses an O-ring sealing arrangement with a straight-thread port.
This combination allows the fitting to connect different hydraulic components without requiring several separate adapters.
Adjustable ORB Stud
One of the most useful features of FS6804 is the adjustable ORB center connection.
After the fitting is positioned in the hydraulic system, the ORB stud can be oriented to achieve the required outlet direction before final tightening. This is especially useful where hose routing needs to be controlled or where a fixed tee would leave the connection facing the wrong direction.
It can also help reduce unnecessary hose twisting and improve the overall arrangement of the hydraulic assembly.
ORFS Face-Seal Connections
The two ORFS ports use O-Ring Face Seal technology. The sealing surface uses an elastomeric O-ring to create a reliable connection with the compatible mating component.
For best sealing performance, the correct ORFS size should be used and the sealing surfaces and O-rings should be inspected before assembly.
This design is particularly useful in hydraulic systems where vibration, pressure cycling, and leakage control are important.
Steel Construction for Hydraulic Equipment
Gear House Hydraulics lists FS6804 as a steel hydraulic fitting.
The steel construction makes the fitting suitable for demanding hydraulic environments where components can experience pressure, vibration, mechanical loads, and continuous equipment operation.
Industry specifications for the FS6804 series also identify carbon steel, forged construction, and trivalent zinc plating.
High-Pressure Capability
The Gear House collection lists working pressures up to 6,000 PSI, depending on tube and fitting size, and identifies the FS6804 for applications involving continuous mechanical shock.
Actual pressure capability should always be confirmed for the specific size and complete hydraulic assembly, including tubing, hoses, mating fittings, and operating conditions.
Why Use an Adjustable Run Tee?
A fixed tee works well when all three connection points naturally line up with the hydraulic circuit. But in real equipment, hose and tube routing is often affected by surrounding components.
The adjustable center stud gives the FS6804 additional installation flexibility.
It can help:
- Position the branch connection correctly
- Improve hose routing
- Reduce unnecessary bends
- Avoid interference with nearby components
- Simplify hydraulic line installation
- Maintain a cleaner equipment layout
- Connect ORFS and ORB systems in one fitting

Frequently Asked Questions
What is an FS6804 fitting?
FS6804 is a three-port hydraulic run tee with two Male ORFS connections and one Male Adjustable ORB connection.
Is the ORB connection adjustable?
Yes. The center ORB connection is an adjustable stud, allowing the outlet to be oriented during installation.
What is the connection configuration?
The standard configuration is Male ORFS × Male Adjustable ORB × Male ORFS.
What material is FS6804 made from?
Gear House lists the fitting as steel. Industry specifications identify the series as carbon steel with forged construction.
What pressure can FS6804 handle?
Gear House lists working pressure up to 6,000 PSI, depending on tube and fitting size.
What does ORFS mean?
ORFS means O-Ring Face Seal. It uses an O-ring at the face of the connection to provide the sealing interface.
What does ORB mean?
ORB means O-Ring Boss. The connection uses straight threads with an O-ring to seal against the compatible hydraulic port.
What sizes are available?
The collection includes configurations from 1/4" through 1-1/4", including several reducing combinations.
Where can FS6804 be used?
It is suitable for mobile, industrial, agricultural, construction, and OEM hydraulic applications, especially where vibration and precise line routing are concerns.
Is FS6804 good for tight installation spaces?
Yes. The run-tee design and adjustable ORB stud provide additional control over the direction and positioning of the hydraulic connection.
