Part #: W46
SAE ORB Female x Code 61 Flange Pad Adapter
Product Overview
The Delphi Fittings Part W46 is a specialized flange pad adapter, also known as a block flange or monoblock flange adapter. It is precision-machined from high-quality carbon steel and designed to provide a direct and robust connection from a component surface with an SAE Code 61 bolt pattern to a male SAE O-Ring Boss (ORB) fitting. This one-piece adapter features an integral Code 61 flange head with an O-ring groove on its base, which seals directly against the component's flat port face. The other connection point is a female SAE ORB port, machined to accept a standard male ORB fitting. Unlike traditional flange head adapters that use separate split flange clamps, the W46 pad adapter is bolted directly to the component using its integrated bolt holes. Typically zinc-plated for excellent corrosion resistance, the W46 adapter conforms to SAE J518 (for the flange pattern) and SAE J1926 (for the ORB port) standards, ensuring reliable performance in hydraulic systems.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Female SAE O-Ring Boss (ORB) (port geometry conforming to SAE J1926-1 / ISO 11926-1) |
| End 2 Configuration | SAE Code 61 Flange Pad (integral flange head with O-ring groove and bolt holes, dimensions conforming to SAE J518 / ISO 6162-1 for Code 61 port pattern) |
| Body Style | Straight Flange Pad / Block Flange Adapter. |
| Sealing Mechanism | ORB Female End: Designed to seal with the O-ring on a mating male SAE ORB fitting. Flange End: Utilizes an elastomeric O-ring (seated in the groove on the flange pad face) which compresses against the flat surface of the mating Code 61 port. The adapter is secured directly by bolts through its integral flange holes. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability. |
| Primary Function | To provide a direct, bolted Code 61 flange connection to a component port, adapting it to a female SAE ORB port for connection with a male ORB fitting. |
| Working Pressure | Suitable for standard duty high-pressure hydraulic systems as defined by SAE Code 61 (typically 3000-5000 PSI depending on size). |
| O-Ring Material (for Flange end of W46) | Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request for specific fluid or temperature compatibility. The O-ring is supplied with the flange pad of this adapter. |
Commonly Available Sizes (Part #W46 Series)
Delphi Fittings offers the SAE ORB Female x Code 61 Flange Pad Adapter in various common ORB and Code 61 flange sizes.
Examples include (Female ORB x Code 61 Flange Size):
- W46-08-08: -08 (3/4-16 UNF) Female ORB x 1/2" (-08) Code 61 Flange Pad
- W46-10-10: -10 (7/8-14 UNF) Female ORB x 5/8" (-10) Code 61 Flange Pad
- W46-12-12: -12 (1-1/16-12 UN Thread) Female ORB x 3/4" (-12) Code 61 Flange Pad
- W46-16-16: -16 (1-5/16-12 UN Thread) Female ORB x 1" (-16) Code 61 Flange Pad
Note: The flange pad includes an appropriate O-ring for sealing against the component. The female ORB port is designed to accept a standard male ORB fitting, which will have its own O-ring. This adapter is bolted directly to the component port; ensure bolt lengths and grades are suitable for the application. For unlisted size combinations, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.
Applications
The Part W46 SAE ORB Female x Code 61 Flange Pad Adapter is ideal for:
- Directly mounting to hydraulic components (such as pumps, motors, valves, and manifolds) that have a SAE Code 61 port pattern, providing a female SAE ORB port for connection to a male ORB fitting or hose end.
- Applications where a compact, one-piece flange connection is preferred for its strength and to reduce potential leak paths, adapting to an ORB connection.
- Use in mobile equipment, industrial machinery, and various hydraulic systems requiring a secure and reliable transition from a Code 61 flange port to an ORB threaded connection.
- Installations where space constraints favor a block-style flange adapter and an ORB interface is desired for its high-pressure sealing capabilities.
Installation & Usage Guidelines
- Ensure the Code 61 flange pad face, its O-ring groove and O-ring, the mating component port surface, and the female ORB port threads are meticulously clean, undamaged, and entirely free from any contaminants.
- Verify that the O-ring for the flange end of the W46 adapter is the correct size and material for the application and is properly lubricated with a system-compatible fluid.
- Carefully install the lubricated O-ring into the groove on the flange pad face.
- Position the flange pad squarely against the mating Code 61 port face on the component, ensuring the bolt holes align correctly.
- Insert the appropriate mounting bolts (typically four, with lock washers if specified by the equipment manufacturer) through the integral flange holes of the W46 adapter and into the tapped holes in the component port.
- Lightly snug all bolts. Then, tighten them progressively and evenly in a diagonal or cross-pattern sequence to the manufacturer's recommended torque specification for the flange size and bolt grade to ensure even O-ring compression.
- For the female ORB end of the adapter, ensure the mating male ORB fitting has its O-ring correctly installed and lubricated. Thread the male ORB fitting into the female ORB port of the adapter and tighten to the recommended torque specification for the ORB size.
- Use appropriate backup wrenches on the hex features of the adapter body when tightening the male ORB fitting, if necessary and design permits.
Why Choose Delphi Fittings Part W46?
- Integrated and Compact Design: The one-piece flange pad (block flange) offers a strong, direct connection to Code 61 ports with a female ORB port, minimizing component count and potential leak paths.
- Reliable Dual O-Ring Sealing: Combines the secure bolted Code 61 flange O-ring seal on the component side with the high-integrity SAE O-Ring Boss seal provided by the mating male ORB fitting.
- Simplified Assembly in Specific Applications: Can reduce complexity compared to using multiple separate adapters for transitioning between flange and ORB connections.
- Standard Compliance: Meets SAE J518 (Code 61) for the flange pattern and SAE J1926 for the ORB port, ensuring compatibility.
- Durable Carbon Steel Construction: Manufactured from high-grade carbon steel for exceptional strength and longevity in demanding industrial and mobile environments.
- Enhanced Corrosion Resistance: Standard zinc plating provides robust protection against rust and other environmental factors.
- Quality-Assured Manufacturing: Produced under Delphi Fittings' rigorous ISO 9001:2015 certified quality management system.
