Part #: W604
ORFS Male x Code 62 Flange Pad Adapter
Product Overview
The Delphi Fittings Part W604 is a specialized high-pressure flange pad adapter, also known as a block flange or monoblock flange adapter. It is precision-engineered from high-quality carbon steel to provide a direct and extremely robust connection from a component surface with an SAE Code 62 (heavy-duty) bolt pattern to a female SAE O-Ring Face Seal (ORFS) swivel fitting. This one-piece adapter features an integral Code 62 flange head with an O-ring groove on its base for sealing against the component port, and a male ORFS connection on the other end. Unlike standard flange head adapters that require separate split flange clamps, this pad adapter is bolted directly to the component, offering a compact and exceptionally strong connection. Typically zinc-plated for corrosion resistance, the W604 conforms to SAE J518 (for the Code 62 flange pattern) and SAE J1453 (for the ORFS end) standards, ensuring superior performance in the most demanding hydraulic applications.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| End 2 Configuration | SAE Code 62 Flange Pad (Heavy Duty) (integral flange head with O-ring groove and bolt holes, dimensions conforming to SAE J518 / ISO 6162-2 for Code 62 port pattern) |
| Body Style | Straight Flange Pad / Block Flange Adapter. |
| Sealing Mechanism | ORFS End: Utilizes an elastomeric O-ring (seated in its groove) which compresses against the flat face of the mating female ORFS swivel 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 62 port. The adapter is secured directly by high-strength bolts through its integral flange holes. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability. |
| Primary Function | To provide a direct, bolted Code 62 flange connection to a component port, adapting it to a male ORFS connection for a female ORFS swivel fitting in high-pressure systems. |
| Working Pressure | Suitable for heavy-duty high-pressure hydraulic systems as defined by SAE Code 62 (typically up to 6000 PSI). |
| O-Ring Material (for both ends) | Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request. O-rings are supplied with the fitting. |
Commonly Available Sizes (Part #W604 Series)
Delphi Fittings offers the ORFS Male x Code 62 Flange Pad Adapter in various common ORFS and Code 62 flange sizes for high-pressure applications.
Examples include (Male ORFS x Code 62 Flange Size):
- W604-08-08: 1/2" (-08) ORFS Male x 1/2" (-08) Code 62 Flange Pad
- W604-12-12: 3/4" (-12) ORFS Male x 3/4" (-12) Code 62 Flange Pad
- W604-16-16: 1" (-16) ORFS Male x 1" (-16) Code 62 Flange Pad
- W604-20-20: 1-1/4" (-20) ORFS Male x 1-1/4" (-20) Code 62 Flange Pad
Note: Each male end includes an appropriate O-ring. This adapter is bolted directly to the component port; ensure appropriate high-strength bolt lengths and grades are used for Code 62 applications. For unlisted size combinations, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.
Applications
The Part W604 ORFS Male x Code 62 Flange Pad Adapter is specifically designed for:
- Directly mounting to high-pressure hydraulic components (such as heavy-duty pumps, motors, valves, and manifolds) that have a SAE Code 62 port pattern, providing a male ORFS connection.
- Applications where a compact, one-piece, and extremely strong flange connection is preferred for maximum pressure containment and superior vibration resistance.
- Use in severe-duty mobile equipment (large excavators, mining machinery, forestry equipment), industrial machinery (high-tonnage presses), and various hydraulic systems requiring a secure transition from a Code 62 flange port to an ORFS line.
Installation & Usage Guidelines
- Ensure the Code 62 flange pad, its O-ring groove and O-ring, the mating port surface, the ORFS male end flat face and O-ring groove, and the mating female ORFS swivel face are all meticulously clean, undamaged, and free from contaminants.
- Verify that the O-rings for both ends are the correct size and material for the high-pressure application and are properly lubricated with system-compatible fluid.
- Carefully install the lubricated O-rings into the grooves on the flange pad face and the ORFS male end.
- Position the flange pad squarely against the mating Code 62 port face on the component, ensuring the bolt holes align correctly.
- Insert the appropriate high-strength mounting bolts through the integral flange holes of the W604 adapter and into the tapped holes in the component port. Tighten bolts progressively and evenly in a diagonal pattern to the recommended torque for Code 62.
- Connect the male ORFS end of the adapter to a mating female ORFS swivel fitting. Hand-tighten the swivel nut until faces meet, then tighten to the recommended torque using appropriate wrenches, backing up the adapter body if necessary.
Why Choose Delphi Fittings Part W604?
- Maximum Pressure Integrated Design: The one-piece Code 62 flange pad offers an exceptionally strong, direct connection to high-pressure ports, adapting to the superior ORFS sealing system.
