Two Swivel Ends for Easier Assembly
The defining feature of FS6565 is the female swivel connection on both ends.
Unlike a fixed union, the swivel ends provide rotational flexibility during installation. This can make alignment easier when two hydraulic hose or tube assemblies need to be connected without forcing them into a particular orientation.
The swivel design is especially useful when working with:
- Limited installation space
- Pre-assembled hydraulic hoses
- Hydraulic manifolds
- Equipment with difficult port alignment
Mobile machinery
Service and maintenance applications
ORFS Flat-Face Sealing
Both ends of FS6565 use the ORFS (O-Ring Face Seal) connection system.
ORFS fittings seal at the flat face using an elastomeric O-ring. When properly assembled with the correct mating components, the face seal provides reliable leakage control in hydraulic applications.
This makes FS6565 a practical option for systems where vibration, pressure cycling, and hydraulic fluid leakage need to be controlled.
Forged Carbon Steel Construction
FS6565 is designed with a forged carbon steel body for strength and durability in demanding hydraulic environments.
The robust construction makes it suitable for applications where fittings may experience continuous vibration, mechanical shock, pressure fluctuations, and repeated machine operation.
A protective finish helps provide additional resistance against corrosion and environmental exposure.
When a Swivel Union Makes Sense
A swivel union can be particularly useful when two female ORFS connections need to be joined but their final orientation cannot easily be controlled.
Instead of forcing a hose or tube into alignment, the swivel arrangement gives the installer more freedom to position the connection before applying final torque.
This can help:
- Improve assembly alignment
- Reduce hose installation stress
- Simplify maintenance
- Accommodate small alignment differences
- Make close-coupled connections easier
Improve hydraulic line organization
Designed for Better Hydraulic Alignment
FS6565 is more than a basic straight union. Its dual-swivel design gives installers additional freedom when positioning hydraulic connections.
This is valuable when hose orientation, equipment movement, or limited access makes a fixed connection difficult to install.
By combining two female ORFS swivel ends with a compact straight body, FS6565 provides a practical connection for hydraulic systems where sealing reliability and installation flexibility are both important.
Why Choose Gear House Hydraulics?
Gear House Hydraulics provides FS6565 ORFS swivel unions for professional hydraulic applications requiring dependable ORFS connections.
Before selecting a fitting, confirm the ORFS size, mating connection type, available clearance, pressure requirements, and hose or tube specifications of the complete assembly.
Choosing the correct configuration helps ensure proper fitment and reliable hydraulic operation.
Frequently Asked Questions
What is an FS6565 fitting?
FS6565 is an ORFS Female Swivel × ORFS Female Swivel straight union designed to connect two compatible ORFS male connections.
What makes FS6565 different from a fixed ORFS union?
FS6565 has swivel connections on both ends, providing greater flexibility for alignment and installation than a fixed union.
What type of seal does FS6565 use?
It uses the ORFS O-Ring Face Seal system on both connections.
What material is FS6565 made from?
The fitting is constructed from forged carbon steel for demanding hydraulic applications.
What is the benefit of having two swivel ends?
Dual swivel ends allow greater rotational flexibility during assembly, which can make alignment easier and help reduce installation stress on connected hoses.
Where is FS6565 commonly used?
It can be used in mobile hydraulics, construction equipment, industrial machinery, hydraulic manifolds, agricultural equipment, mining equipment, and OEM hydraulic assemblies.
Is FS6565 suitable for high-pressure hydraulics?
It is designed for demanding hydraulic applications. The actual working pressure must be confirmed for the selected size and complete hydraulic assembly.
How do I select the correct FS6565 size?
Match both female ORFS swivel ends to the correct ORFS male connection size used by your hydraulic hoses, tubes, or adapters.
Is FS6565 a 90° elbow?
No. FS6565 is a straight union. Its purpose is to connect two ORFS lines while providing swivel flexibility.
