A Simple Way to Connect ORFS and JIC
Hydraulic equipment often uses different connection styles across hoses, valves, manifolds, and other components. FS6402 provides a direct solution when a Male ORFS connection needs to connect to a Female JIC hose or fitting.
The straight body keeps the connection inline rather than changing the direction of the hydraulic line.
Male ORFS → Straight Adapter → Female JIC Swivel
This makes FS6402 useful for hydraulic repairs, hose assemblies, equipment modifications, and applications where ORFS and JIC components need to work together.
Female JIC Swivel for Easier Installation
One of the most useful features of FS6402 is the Female JIC swivel end.
The swivel allows the hose or mating JIC connection to be positioned more easily before final tightening. This is particularly useful when working with hydraulic hoses that need to be aligned with a fixed port.
The swivel design can help with:
- Easier hose positioning
- Better connection alignment
- Reduced twisting during assembly
- Faster installation
- Easier service and maintenance
- Hydraulic connections in limited spaces
The swivel does not change the basic connection type; it simply provides additional rotational flexibility during assembly.
ORFS O-Ring Face Seal
The Male ORFS end uses an O-Ring Face Seal.
Instead of relying only on tapered threads, ORFS fittings use a flat sealing face and an elastomeric O-ring to create the sealing interface. This design is commonly selected for hydraulic applications where leakage control and resistance to vibration are important.
The O-ring should always be inspected for damage, correct size, and proper seating before installation.
37° Female JIC Swivel Connection
The opposite end uses a Female 37° JIC swivel.
JIC fittings use a 37-degree flare seating surface to create the connection with a compatible male JIC fitting. This makes FS6402 useful for connecting ORFS hydraulic ports to existing JIC hoses and components.
The female swivel also makes it easier to orient the hose without forcing the hose itself into an unwanted position.
Carbon Steel Construction
FS6402 is manufactured from carbon steel and is listed with trivalent zinc plating for improved corrosion resistance. Forged construction provides a strong body for demanding hydraulic applications.
This construction is suitable for equipment exposed to:
- Hydraulic pressure
- Mechanical vibration
- Pressure cycling
- Repeated installation and service
- Mobile equipment movement
- Industrial operating conditions
Straight Configuration for Inline Connections
FS6402 is a straight adapter, so it is best suited to installations where the ORFS and JIC connections can be positioned along the same general line.
If the hydraulic line needs a directional change, an elbow configuration may be more appropriate. For a direct ORFS-to-JIC connection, FS6402 keeps the assembly compact and straightforward.
Where FS6402 Is Used
FS6402 Male ORFS to Female JIC Swivel adapters are suitable for:
- Hydraulic hose assemblies
- Mobile hydraulic equipment
- Construction machinery
- Agricultural equipment
- Industrial hydraulic systems
- Hydraulic manifolds
- Pumps and valves
- Hydraulic cylinders
- OEM equipment
- Fluid power systems
- Hydraulic repair and maintenance
The adapter is especially useful when replacing or modifying hydraulic components that use different connection styles.

- Useful for ORFS-to-JIC transitions
When Should You Choose FS6402?
Choose FS6402 when you have:
A Male ORFS port + a Female JIC hose/fitting
and need a straight connection with swivel flexibility.
It is particularly useful when the JIC hose needs to rotate into position during installation rather than being fixed at one orientation.
For example, if a hydraulic machine has an ORFS port but the replacement hose has a female JIC swivel end, FS6402 can provide the connection between the two systems.
How to Select the Correct Size
Before ordering FS6402, verify both connection sizes.
ORFS Size:
Match the Male ORFS end with the compatible Female ORFS port.
JIC Size:
Match the Female JIC swivel with the compatible Male JIC 37° flare.
Thread Size:
Do not select the fitting based only on the outside appearance. Confirm the actual JIC thread size and fitting dash size.
Configuration:
FS6402 is a straight swivel adapter. Make sure your installation does not require a 45° or 90° elbow.
