Part #: 1804 / NB6892
37° JIC Male x Code 62 Flange 90° Elbow
Product Overview
The Delphi Fittings Part 1804 (also referenced as NB6892) is a 90° elbow flange head adapter, specifically engineered for high-pressure hydraulic systems. This fitting creates a secure, right-angle 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 90-degree angle. This adapter is designed for use with a Code 62 split flange kit (two halves, high-strength bolts, and washers) or a captive flange, which clamp the flange head to the port face, compressing the O-ring for a superior, leak-proof seal. The male JIC end allows for straightforward connection to female JIC swivel fittings on hydraulic hoses or tubes. Manufactured from high-quality carbon steel and zinc-plated for enhanced corrosion resistance, this adapter conforms to SAE J518 (Code 62 flange) and SAE J514 (JIC) standards, ensuring reliability in the most demanding hydraulic environments that require a 90-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 | 90 Degrees |
| Body Style | 90° 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. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Primary Function | To provide a 90-degree, high-pressure, leak-proof connection from a SAE Code 62 flange port to a female JIC swivel fitting or flared tube, facilitating a right-angle take-off for hydraulic lines. |
| 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 #1804 / NB6892 Series)
Delphi Fittings offers the 37° JIC Male x Code 62 Flange 90° Elbow in a variety of common JIC and Code 62 flange sizes for high-pressure applications.

Applications
The Part 1804 / NB6892 JIC Male x Code 62 Flange 90° 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 like pumps, motors, valves, and heavy-duty manifolds, where a 90-degree change in line direction is essential for routing.
- Integrating JIC standard lines into systems that utilize Code 62 flange connections for maximum pressure handling and reliability, particularly when an immediate right-angle turn is needed.
- Use in severe-duty mobile equipment (e.g., large excavators, mining machinery, forestry equipment), industrial machinery (e.g., high-tonnage presses), and various hydraulic systems where robust, bolted flange connections are critical for safety and performance at extreme pressures.
- Applications demanding superior resistance to vibration, pressure spikes, and mechanical stress, combined with a 90-degree 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.
- Carefully install the lubricated O-ring into the groove on the flange head of the adapter.
- Position the flange head against the mating Code 62 port face, orienting the elbow to the desired 90-degree direction 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.
- 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 (not the flare itself). Tighten the JIC swivel nut to the recommended torque for the specific JIC size.
- Always use appropriate backup wrenches on the elbow body and mating components during the tightening process.
