A 37° flare tool is a specialized tool used to create a precise 37-degree flare at the end of metal tubing, typically for use in hydraulic or fuel line applications. This type of flare is a standard in the aerospace and automotive industries, as it forms a leak-free, high-pressure connection when paired with AN (Army-Navy) or JIC (Joint Industry Council) fittings. These fittings are popular because they provide reliable and reusable connections.
Features of a 37° Flare Tool:
Flare Angle: It creates a 37-degree flare, which differs from the 45-degree standard used in plumbing or refrigeration.
Material Compatibility: Often used on aluminum, steel, stainless steel, or copper tubing.
Construction: Typically made from hardened steel to handle high-strength materials.
Adjustable Dies: Many tools come with interchangeable dies or adapters for different tubing sizes.
Hand or Bench Operation: Available as manual hand tools or bench-mounted units for repetitive tasks.
How to Use a 37° Flare Tool:
Cut the Tubing: Use a tubing cutter to ensure a clean, square cut.
Deburr the Edges: Remove any burrs or sharp edges from the tubing.
Position the Tube: Insert the tube into the flare tool die at the correct position.
Secure the Tube: Clamp it firmly to avoid movement during flaring.
Flare the Tube: Operate the tool according to its design (manual or hydraulic) to form the flare.
