37° JIC Male x Code 61 Flange Adapter - Part 1700 / NB6840

Part #: 1700 / NB6840

37° JIC Male x Code 61 Flange Adapter

Product Overview

The Delphi Fittings Part 1700 (also referenced as NB6840) is a straight flange head adapter designed to connect a SAE Code 61 flange port to a JIC (37° flare) connection. This adapter features a Code 61 flange head with an O-ring groove on one end and a male JIC 37° flare on the other. It is used in conjunction with a Code 61 split flange kit (two halves, bolts, and washers) or a captive flange to create a secure, high-pressure seal against the flat face of a Code 61 port on components like pumps, motors, or valves. 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 (for the flange end) and SAE J514 (for the JIC end) standards, ensuring reliability in demanding hydraulic systems.

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)
Body Style Straight Flange Head Adapter, typically with a 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 straight, leak-proof connection from a SAE Code 61 flange port to a female JIC swivel fitting or flared tube.
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 #1700 / NB6840 Series)

Delphi Fittings offers the 37° JIC Male x Code 61 Flange Adapter in a variety of common JIC and Code 61 flange sizes.

Examples include (Male JIC x Code 61 Flange Size):

  • 1700-08-08 / NB6840-08-08: 1/2" (-08) JIC Male x 1/2" (-08) Code 61 Flange
  • 1700-10-10 / NB6840-10-10: 5/8" (-10) JIC Male x 5/8" (-10) Code 61 Flange
  • 1700-12-12 / NB6840-12-12: 3/4" (-12) JIC Male x 3/4" (-12) Code 61 Flange

  • 1700-20-20 / NB6840-20-20: 1-1/4" (-20) JIC Male x 1-1/4" (-20) Code 61 Flange
  • 1700-24-24 / NB6840-24-24: 1-1/2" (-24) JIC Male x 1-1/2" (-24) 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 1700 / NB6840 JIC Male x Code 61 Flange Adapter is ideal for:

  • Connecting hydraulic hoses or tubes with female JIC swivel ends to SAE Code 61 flange ports on hydraulic pumps, motors, valves, cylinders, and manifolds.
  • Integrating JIC standard lines into systems that utilize Code 61 flange connections for higher pressure or larger diameter porting.
  • Use in mobile equipment (construction, agriculture, forestry), industrial machinery, and various hydraulic systems where a secure and reliable transition from a flange port to a JIC connection is needed.
  • Applications requiring a robust, bolted connection that offers excellent resistance to vibration and pressure fluctuations.

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. 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. Ensure even O-ring compression.
  • 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 JIC size.
  • Use backup wrenches where appropriate during tightening.
