37° JIC to Flareless Compression Convert-A-Flare Sleeve - Part 419

Part Number: 419

37° JIC to Flareless Compression Convert-A-Flare Sleeve

Product Overview

The Delphi Fittings Part 419 is a 37° JIC to Flareless Compression Convert-A-Flare Sleeve, often referred to as a ferrule. This precision-engineered component is specifically designed to be used in conjunction with the Convert-A-Flare Nut (Delphi Part #418) to facilitate the connection of an un-flared hydraulic tube directly to a standard male JIC 37° flare fitting. When the Part 418 nut is tightened, this Part 419 sleeve compresses onto the outer diameter of the tube, creating a strong, bite-type seal and a secure mechanical grip. This innovative system entirely eliminates the need for a separate tube flaring operation, providing a convenient and efficient solution for various hydraulic plumbing applications, particularly in field service or where flaring tools are impractical. Manufactured from high-quality carbon steel, it is designed for optimal performance and durability.

Key Features & Specifications

Material High-Grade Carbon Steel (often case-hardened for an effective bite into the tube)
Design Single-bite or double-bite compression sleeve (ferrule) specifically engineered for the Convert-A-Flare system.
Compatibility Must be used with the 37° JIC to Flareless Compression Convert-A-Flare Nut (Delphi Part #418) of the corresponding size. Suitable for un-flared hydraulic tubing of appropriate material (e.g., steel, stainless steel) and specified wall thickness.
Sealing Mechanism Forms a high-integrity compression seal by progressively biting into the outer surface of the un-flared tube when compressed by the Part 418 nut. The assembly then presents a JIC-compatible interface to the male JIC 37° flare.
Surface Treatment Appropriate surface treatment for hardness, performance, and corrosion resistance (e.g., phosphated, lightly oiled, or specific plating compatible with bite-type function).
Primary Function To create the compression grip and fluid seal on an un-flared hydraulic tube, enabling its connection to a male JIC 37° flare fitting when used with the Part 418 Convert-A-Flare Nut.
Working Pressure Contributes significantly to the overall pressure rating of the Convert-A-Flare assembly. The rating is dependent on tube material, tube wall thickness, and correct installation procedures. It is recommended to consult Delphi Fittings' technical documentation for specific pressure ratings for the complete assembly.

Commonly Available Sizes (Part #419 Series)

Delphi Fittings offers the Convert-A-Flare Sleeve in sizes corresponding to common hydraulic tube outer diameters (OD) and the Convert-A-Flare Nut (Part #418) they are designed to work with.

Examples (Sleeve size corresponds to the tube OD and the mating Part #418 Nut):

  • 419-04: For 1/4" Tube OD (used with 418-04 Nut)
  • 419-06: For 3/8" Tube OD (used with 418-06 Nut)
  • 419-08: For 1/2" Tube OD (used with 418-08 Nut)
  • 419-10: For 5/8" Tube OD (used with 418-10 Nut)
  • 419-12: For 3/4" Tube OD (used with 418-12 Nut)

Note: This sleeve must be used with the corresponding JIC to Flareless Compression Convert-A-Flare Nut (Delphi Part #418) of the same dash size. Ensure that the selected tube material and wall thickness are suitable for this type of compression fitting. For unlisted sizes or specific application advice, please contact our sales team.

Applications

The Part 419 Convert-A-Flare Sleeve is a critical component for:

  • The Convert-A-Flare system, enabling the connection of un-flared rigid metal tubing to standard male JIC 37° flare fittings.
  • Hydraulic system installations, field repairs, or modifications where tube flaring is not desired, practical, or feasible.
  • Providing a reliable alternative to flaring in various industries, including mobile equipment, industrial machinery, agriculture, and maintenance operations.
  • Applications requiring a secure, bite-type seal on hydraulic tubes for JIC system integration.

Installation & Usage Guidelines

  • Ensure the end of the un-flared hydraulic tube is cut squarely, is clean, and has been thoroughly deburred both internally and externally. The tube surface must be free from deep scratches or damage.
  • Slide the Convert-A-Flare Nut (Part #418) onto the tube first, with the threads of the nut facing the tube end.
  • Slide the Part 419 Convert-A-Flare Sleeve onto the tube. Ensure the sleeve is oriented correctly according to its design (typically, the cutting edge or tapered compression section of the sleeve should face the tube end that will be inserted into the fitting).
  • Insert the tube with the nut and sleeve fully into the mating male JIC 37° flare fitting until the tube bottoms out against the fitting's internal stop or the sleeve seats correctly within the nut and fitting cone.
  • Hand-tighten the nut onto the male JIC fitting.
  • While securely holding the male JIC fitting stationary with a backup wrench, use another wrench to tighten the Part 418 nut. Adhere strictly to Delphi Fittings' recommended tightening procedure (this usually involves a specific number of turns from the finger-tight position, or tightening to a specified torque if provided) to ensure the sleeve correctly bites into the tube surface and forms a secure, leak-proof seal without over-stressing the tube or components.
  • Important: The Convert-A-Flare sleeve creates a permanent deformation (bite) on the tube. For this reason, it is generally not recommended to disassemble and reassemble this type of compression connection multiple times on the exact same section of tubing, as the integrity of the seal may be compromised.

Why Choose Delphi Fittings Part 419?

  • Essential for Flareless JIC Connections: This sleeve is the critical element that forms the compression seal and mechanical grip on the un-flared tube within the Convert-A-Flare system.
  • Facilitates No-Flare Assembly: Works in tandem with the Part 418 nut to save significant time, labor, and the need for specialized tube flaring tools and expertise.
  • Reliable Bite-Type Seal: Engineered to provide a strong, high-pressure, leak-proof compression seal when correctly installed.
  • Durable Material: Manufactured from high-quality, often case-hardened, carbon steel to ensure an effective bite into the tube and long-term durability.
  • Precision System Compatibility: Specifically designed to work seamlessly with Delphi Part 418 Convert-A-Flare Nuts and standard male JIC 37° flare fittings.
  • Quality Manufacturing: Produced under Delphi Fittings' rigorous ISO 9001:2015 certified quality management system, ensuring consistency and reliability.
