DELPHI FITTINGS
Part #: 1703 / NB6845
37° JIC Male x Code 61 Flange 45° Elbow
Product Overview
The Delphi Fittings Part 1703 (also referenced as NB6845) is a 45° elbow flange head adapter. It is engineered to create a secure, angled connection between a SAE Code 61 flange port and a JIC (37° flare) hydraulic line. This fitting features a Code 61 flange head with an O-ring groove on one end, and a male JIC 37° flare on the other, with the two ends oriented at a 45-degree angle. It is designed to be used with a Code 61 split flange kit (two halves, bolts, and washers) or a captive flange, which clamp the flange head to the port face, compressing the O-ring for a reliable seal. The male JIC end allows for easy connection to female JIC swivel fittings on hydraulic hoses or tubes. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, this adapter conforms to SAE J518 (flange) and SAE J514 (JIC) standards, ensuring robust performance in high-pressure hydraulic systems requiring a 45-degree directional change at the flange connection point.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Male 37° JIC Flare (conforming to SAE J514 / ISO 8434-2) |
| End 2 Configuration | SAE Code 61 Flange Head (conforming to SAE J518 / ISO 6162-1) |
| Angle | 45 Degrees |
| Body Style | 45° Elbow Flange Head Adapter, typically forged for strength, with hex or flats for orientation. |
| Sealing Mechanism | JIC End: Achieves a metal-to-metal seal on the 37° flare cone. Flange End: Utilizes an elastomeric O-ring (seated in the groove on the flange head) which compresses against the flat face of the mating Code 61 port, secured by a split or captive flange kit. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Primary Function | To provide a 45-degree, leak-proof connection from a SAE Code 61 flange port to a female JIC swivel fitting or flared tube, facilitating an angled take-off. |
| 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) | Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request. O-ring is supplied with the fitting. |
Commonly Available Sizes (Part #1703 / NB6845 Series)
Delphi Fittings offers the 37° JIC Male x Code 61 Flange 45° Elbow in a variety of common JIC and Code 61 flange sizes.
Examples include (Male JIC x Code 61 Flange Size):
- 1703-08-08 / NB6845-08-08: 1/2" (-08) JIC Male x 1/2" (-08) Code 61 Flange
- 1703-10-10 / NB6845-10-10: 5/8" (-10) JIC Male x 5/8" (-10) Code 61 Flange
- 1703-12-12 / NB6845-12-12: 3/4" (-12) JIC Male x 3/4" (-12) Code 61 Flange
- 1703-16-16 / NB6845-16-16: 1" (-16) JIC Male x 1" (-16) Code 61 Flange
Note: Each flange head includes an appropriate O-ring. This adapter requires a separate Code 61 split flange kit (e.g., Part 61SF-KIT) or captive flange and bolts for installation. For unlisted size combinations, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.
Applications
The Part 1703 / NB6845 JIC Male x Code 61 Flange 45° Elbow is ideal for:
- Connecting JIC hydraulic lines (hoses or tubes with female JIC swivel ends) to SAE Code 61 flange ports on hydraulic components like pumps, motors, valves, and cylinders, where a 45-degree change in direction is required for optimal routing.
- Integrating JIC standard lines into systems that utilize Code 61 flange connections, allowing for a smoother bend than a 90-degree elbow.
- Use in mobile equipment, industrial machinery, agricultural equipment, and various hydraulic systems where a secure and reliable angled transition from a flange port to a JIC connection is needed.
- Applications requiring a robust, bolted flange connection that offers excellent resistance to vibration and pressure fluctuations, with a 45-degree take-off.
Installation & Usage Guidelines
- Ensure the Code 61 flange head, O-ring groove, O-ring, mating port surface, and JIC flare are all clean, undamaged, and free from contaminants.
- Verify that the O-ring is the correct size and material for the application and is properly lubricated with system-compatible fluid.
- Carefully install the lubricated O-ring into the groove on the flange head of the adapter.
- Position the flange head against the mating Code 61 port face, orienting the elbow to the desired 45-degree angle. Place the split flange halves (or captive flange) behind the flange head.
- Insert the four mounting bolts (with lock washers) through the flange halves/captive flange and into the tapped holes in the port.
- Lightly snug all bolts, then tighten them progressively and evenly in a diagonal or cross pattern to the manufacturer's recommended torque for the Code 61 flange size and bolt grade.
- Connect the male JIC flare end of the adapter to a mating female JIC swivel fitting. Ensure the 37° flare surfaces align correctly. Lightly lubricate the JIC swivel nut threads. Tighten the JIC swivel nut to the recommended torque.
- Use backup wrenches on the elbow body and mating components where appropriate during tightening.
Why Choose Delphi Fittings Part 1703 / NB6845?
