DELPHI FITTINGS
Part Number: 6425
SAE ORB Female x SAE ORB Female Coupler
Product Overview
The Delphi Fittings Part 6425 is an SAE ORB Female x SAE ORB Female Coupler, designed as a straight fitting to connect two male SAE O-Ring Boss (ORB) fittings of the same size. This coupler features female SAE O-Ring Boss ports on both ends, each machined with the necessary internal boss to properly seat and seal the O-ring from the mating male ORB fittings. While it provides a direct ORB-to-ORB connection, its use can be specific as it extends a line composed of two male fittings. The sealing integrity relies entirely on the O-rings of the male fittings being connected. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 6425 offers a solution for specific hydraulic plumbing scenarios.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Female SAE O-Ring Boss (ORB) (per SAE J1926-1 / ISO 11926-1) |
| End 2 Configuration | Female SAE O-Ring Boss (ORB) (per SAE J1926-1 / ISO 11926-1) |
| Body Style | Straight Coupler with Hex Body (or wrench flats) for tightening. |
| Sealing Mechanism | Each female ORB port is designed to seal with the O-ring supplied on the mating male ORB fitting, which compresses against the internal boss of this coupler. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability. |
| Primary Function | To connect two male SAE O-Ring Boss fittings of the same size in a straight line. |
| Usage Note | Use may be limited compared to other adapters; sealing relies on the O-rings of the male fittings being connected. |
| Working Pressure | Suitable for high-pressure hydraulic applications. Specific ratings vary by size. |

Note: Always verify the specific ORB size required for your application. For unlisted sizes, please contact our sales team.
Applications
The Part 6425 SAE ORB Female Coupler is used in specific situations where two male ORB fittings need to be joined directly:
- Extending a hydraulic line that terminates with a male ORB fitting, by connecting it to another male ORB fitting or hose end.
- Joining two male ORB ended components in-line.
- Applications in test stands or temporary setups where a direct male-to-male ORB connection (via this female coupler) is needed.
- Use in modular hydraulic systems where components with male ORB outlets are common.
It's important to note its "limited use" as described on the category page; often, direct component-to-component mounting or using adapters to different thread types is more common than coupling two male ORB fittings in this manner for line extension.
Installation & Usage Guidelines
- Ensure all threads and sealing surfaces (internal bosses of the coupler, O-ring grooves and O-rings on the mating male ORB fittings) are clean, undamaged, and free of contaminants.
- Verify that the O-rings on both male ORB fittings are correctly sized, lubricated with system-compatible fluid, and properly seated in their grooves.
- Thread each male ORB fitting into a female ORB port of the coupler by hand until the O-ring makes contact and the fitting shoulder is snug.
- Use appropriate wrenches on the hex body of the coupler and on the hex of the male ORB fittings to tighten both connections to the recommended torque specification for the ORB size. This ensures proper O-ring compression.
- Avoid over-tightening, which can damage the O-rings or the threads.
