DELPHI FITTINGS
Part #: W304
ORFS Male x Code 61 Flange Pad Adapter
Product Overview
The Delphi Fittings Part W304 is a specialized flange pad adapter (also referred to as a block flange or monoblock flange adapter). It is designed to provide a direct, high-integrity connection from a component surface with a SAE Code 61 bolt pattern to a female SAE O-Ring Face Seal (ORFS) swivel fitting or prepared tube end. This one-piece adapter features an integral Code 61 flange head with an O-ring groove on its base, which mounts directly to a flat port face, and a male ORFS connection extending from the body. Unlike standard flange head adapters that require separate split flange halves for clamping, this pad adapter is typically bolted directly to the component, offering a compact and robust connection. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the W304 adapter conforms to SAE J518 (for the flange pattern) and SAE J1453 (for the ORFS end) standards, ensuring excellent performance in demanding hydraulic systems.
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 61 Flange Pad (integral flange head with 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 | 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 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 male ORFS connection for a female ORFS swivel fitting or prepared tube end. |
| 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 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 #W304 Series)
Delphi Fittings offers the ORFS Male x Code 61 Flange Pad Adapter in various common ORFS and Code 61 flange sizes.
Examples include (Male ORFS x Code 61 Flange Size):
- W304-08-08: 1/2" (-08) ORFS Male x 1/2" (-08) Code 61 Flange Pad
- W304-10-10: 5/8" (-10) ORFS Male x 5/8" (-10) Code 61 Flange Pad
- W304-12-12: 3/4" (-12) ORFS Male x 3/4" (-12) Code 61 Flange Pad
- W304-16-16: 1" (-16) ORFS Male x 1" (-16) Code 61 Flange Pad
Note: Each flange pad and ORFS male end includes an appropriate 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 W304 ORFS Male 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 male ORFS connection for superior sealing.
- Applications where a compact, integrated, and highly reliable flange connection is preferred over using separate flange head adapters and split flange clamps, especially when connecting to ORFS lines.
- Use in mobile equipment, industrial machinery, and various hydraulic systems requiring a robust and secure transition from a Code 61 flange port to an ORFS line, known for its excellent performance in high-vibration environments.
- Situations demanding the high integrity of a bolted flange connection combined with the zero-clearance assembly and superior sealing of ORFS.
Installation & Usage Guidelines
- Ensure the Code 61 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 application and are properly lubricated with system-compatible fluid.
- Carefully install the lubricated O-rings into their respective grooves on the flange pad face and the ORFS male end.
- Position the flange pad squarely against the mating Code 61 port face, aligning the bolt holes.
- Insert the appropriate mounting bolts (typically four, with lock washers if specified) through the integral flange holes of the 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. Ensure even O-ring compression on the flange side.
- 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 W304?
