Yellow Jacket 60297 Flare Sizing Gauge – Precision Tool for HVAC and Refrigeration Line Work

The Yellow Jacket 60297 Flare Sizing Gauge is a compact tool engineered for accurately verifying flare dimensions in copper and aluminum tubing. Designed for field use, this gauge helps confirm compliance with SAE standards to prevent under- or over-flared joints that can lead to leaks or connection failure. It accommodates six standard tubing sizes commonly used in HVAC/R systems.

Constructed from coated aluminum for durability and corrosion resistance, the gauge features laser-etched size markings that remain visible even with frequent handling. A built-in hole allows it to be clipped or hung in a service bag or on a tool board for quick access in tight job site conditions.

Key Features

  • Verifies Flare Accuracy – Quickly checks flare dimensions to ensure correct fit and sealing integrity during brazing or assembly.
  • Laser-Etched Markings – Permanent size indicators won’t fade or wear off during daily use.
  • Coated Aluminum Body – Lightweight and corrosion-resistant for reliable performance in field environments.
  • Six-Slot Design – Compatible with common flare sizes used in refrigeration and air conditioning tubing.
  • Hanging Hole – Enables convenient storage or attachment to tool bags or belts.

Technical Specifications

  • Material: Coated aluminum
  • Compatible Flare Sizes: 1/8″, 3/16″, 1/4″, 5/16″, 3/8″, and 1/2″

Usage Considerations

This gauge is intended for use during fabrication and inspection of flared tubing joints. It helps prevent flare fitting mismatches, reducing the likelihood of joint failure under pressure. Ideal for use when servicing mini-splits, line sets, or refrigeration units. It is not a forming tool but a verification gauge used in conjunction with proper flare tools.

Recommended For

  • HVAC/R service technicians
  • Installation of flared copper or aluminum tubing
  • Routine maintenance of refrigerant line sets
  • Shop-based flare fabrication quality control
