Connect ORFS and JIC Without Changing the Entire Assembly
FS6403 solves a common hydraulic connection problem: connecting an ORFS component to equipment or hose assemblies using 37° JIC connections.
Instead of replacing an entire hydraulic assembly simply because the connection types are different, this adapter provides a direct transition between the two connection systems.
The straight configuration keeps the connection inline, making it suitable for installations where a directional change is not required.
Male ORFS × Male JIC Configuration
The fitting combines:
Male ORFS → Straight Adapter → 37° Male JIC
The Male ORFS end connects with a compatible Female ORFS connection using the O-ring face sealing system.
The opposite 37° Male JIC end connects with a compatible Female JIC connection and creates the standard JIC flare interface.
This makes FS6403 useful when hydraulic equipment contains different connection standards within the same system.
ORFS O-Ring Face Seal
The ORFS side uses a flat-face sealing arrangement with an elastomeric O-ring.
This sealing method is widely used in hydraulic systems where dependable leakage control is important, particularly in equipment exposed to vibration and pressure cycling.
For proper performance, always verify the correct ORFS size and inspect the O-ring and sealing surface before installation.
37° JIC Connection
The JIC side uses a 37-degree flare connection, a common hydraulic connection style used across industrial, mobile, agricultural, and construction equipment.
The JIC connection is useful for hydraulic hose assemblies and equipment where reliable metal-to-metal flare engagement is required.
FS6403 therefore provides a convenient way to integrate JIC components into systems using ORFS connections.
Steel Construction
FS6403 is listed by Gear House Hydraulics in steel construction, providing the strength and durability required for demanding hydraulic applications. The collection currently offers six equal-size configurations ranging from 1/4" × 1/4" through 1" × 1".
Steel construction makes the adapter suitable for equipment exposed to:
- Hydraulic pressure
- Vibration
- Repeated operation
- Mechanical loads
- Industrial working conditions
- Mobile equipment movement
When Should You Use FS6403?
FS6403 is a good choice when your hydraulic system has an ORFS connection on one side and a 37° JIC connection on the other.
Typical situations include:
- Replacing a damaged adapter
- Connecting ORFS hoses to JIC equipment
- Hydraulic system repairs
- Equipment modifications
- Manifold connections
- Pump and valve connections
- Hydraulic hose assemblies
- OEM hydraulic installations
The straight design is especially useful when both hydraulic connections can be aligned without requiring an elbow.

Because ORFS and JIC connections are both common in hydraulic equipment, an adapter such as FS6403 can make system repairs and component replacement much easier.
How to Choose the Correct FS6403 Size
Before ordering, confirm both connection sizes.
Check the ORFS Size:
Match the Male ORFS end with the compatible Female ORFS connection.
Check the JIC Size:
Confirm that the 37° Male JIC end matches the Female JIC connection.
Check the Configuration:
FS6403 is a straight ORFS-to-JIC adapter, not an elbow.
Check System Requirements:
Verify that the fitting, hose, tubing, and mating components are appropriate for the hydraulic system's operating conditions.
Choosing the correct size prevents poor fitment and helps maintain reliable hydraulic performance.
