Part #: 1803 / NB6847
37° JIC Male x Code 62 Flange 45° Elbow
Product Overview
The Delphi Fittings Part 1803 (also referenced as NB6847) is a 45° elbow flange head adapter, specifically designed for high-pressure hydraulic systems. This fitting creates a secure, angled connection between a SAE Code 62 (heavy-duty) flange port and a JIC (37° flare) hydraulic line. It features a Code 62 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. This adapter is used with a Code 62 split flange kit (two halves, high-strength bolts, and washers) or a captive flange, which clamps the flange head to the port face, compressing the O-ring for a superior, leak-proof 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 (Code 62 flange) and SAE J514 (JIC) standards, ensuring reliability in the most demanding hydraulic environments requiring a 45-degree directional change at the flange connection.
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 62 Flange Head (Heavy Duty) (conforming to SAE J518 / ISO 6162-2) |
| Angle | 45 Degrees |
| Body Style | 45° Elbow Flange Head Adapter, typically forged for strength, with hex or flats for orientation during installation. |
| 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 62 port, secured by a split or captive flange kit. |
| Primary Function | To provide a 45-degree, high-pressure, leak-proof connection from a SAE Code 62 flange port to a female JIC swivel fitting or flared tube, facilitating an angled take-off. |
| 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 Flange end) | 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 fitting. |
Commonly Available Sizes (Part #1803 / NB6847 Series)
Delphi Fittings offers the 37° JIC Male x Code 62 Flange 45° Elbow in a variety of common JIC and Code 62 flange sizes for high-pressure applications.
Examples include (Male JIC x Code 62 Flange Size):
- 1803-08-08 / NB6847-08-08: 1/2" (-08) JIC Male x 1/2" (-08) Code 62 Flange
- 1803-10-10 / NB6847-10-10: 5/8" (-10) JIC Male x 5/8" (-10) Code 62 Flange
- 1803-12-12 / NB6847-12-12: 3/4" (-12) JIC Male x 3/4" (-12) Code 62 Flange
- 1803-16-16 / NB6847-16-16: 1" (-16) JIC Male x 1" (-16) Code 62 Flange
Note: Each flange head includes an appropriate O-ring. This adapter requires a separate Code 62 split flange kit (e.g., Part 62SF-KIT) or captive flange and high-strength 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 1803 / NB6847 JIC Male x Code 62 Flange 45° Elbow is specifically designed for:
- Connecting JIC hydraulic lines (hoses or tubes with female JIC swivel ends) to high-pressure SAE Code 62 flange ports on hydraulic components such as pumps, motors, valves, and heavy-duty manifolds, where a 45-degree change in direction is required for optimal routing.
- Integrating JIC standard lines into systems that utilize Code 62 flange connections for maximum pressure handling, allowing for a smoother bend than a 90-degree elbow.
- Use in severe-duty mobile equipment (e.g., large excavators, mining machinery), industrial machinery (e.g., high-tonnage presses), and various hydraulic systems where robust, bolted flange connections are essential for safety and performance at extreme pressures.
- Applications demanding superior resistance to vibration, pressure spikes, and mechanical stress, with an angled take-off from the flange port.
Installation & Usage Guidelines
- Ensure the Code 62 flange head, O-ring groove, O-ring, mating port surface, and JIC flare are all meticulously clean, undamaged, and free from any contaminants.
- Verify that the O-ring is the correct size and material for the high-pressure application and is properly lubricated with system-compatible fluid.
- Position the flange head against the mating Code 62 port face, orienting the elbow to the desired 45-degree angle for the JIC connection. Place the Code 62 split flange halves (or captive flange) behind the adapter's flange head.
- Insert the four high-strength mounting bolts (typically with lock washers) through the flange halves/captive flange and into the tapped holes in the port.
- Lightly snug all four bolts. Then, progressively and evenly tighten the bolts in a diagonal or cross-pattern sequence to the manufacturer's recommended torque specification for the Code 62 flange size and bolt grade. This ensures even O-ring compression and prevents flange distortion.
- Always use appropriate backup wrenches on the elbow body and mating components during the tightening process.
Why Choose Delphi Fittings Part 1803 / NB6847?
- Maximum Pressure Capability at an Angle: Designed for high-pressure Code 62 flange systems, offering a secure 45-degree JIC connection in the most demanding hydraulic environments.
- Robust and Secure Connection: Combines the strength of a bolted Code 62 flange with the reliable JIC 37° flare connection.
- Superior Leak Resistance: The O-ring seal on the flange end provides excellent protection against leakage under extreme pressures and vibrations.
- Optimized Routing: The 45-degree angle allows for smoother line routing compared to a 90-degree elbow in certain system layouts.
