Complete Kit Includes:

1. Heavy-Duty Tube Cutter (70033)

Cuts 1/8" to 1 1/8" O.D. tubing cleanly and squarely without crushing or deforming the tube. Clean cuts are essential for proper flare formation and leak-free connections.

2. Standard 45° Flaring Tool (70051 Metric)

Flares 7 metric sizes: 4, 6, 8, 10, 12, 15 and 16mm O.D. tubing. Creates precision 45° flares on metric copper, aluminium, and brass tubing for leak-free refrigerant line connections.

3. Five Double Flaring Adapters (70192-M)

Covers 4.75, 5, 6, 8 and 10mm O.D. tubing. Produces double flares (inverted flares) required for high-pressure applications such as automotive brake lines and hydraulic systems.

Applications:

• HVAC/R refrigerant line preparation
• Automotive brake line fabrication
• Hydraulic line installation
• Plumbing copper tube work
• Mini-split air conditioner installation
• Metric tube system service and repair
• Mobile service and workshop applications

• Professional Results – Consistent flare quality every time
• Safety – Proper flares critical for brake and refrigerant lines
• Time Saving – Quick, accurate flare formation
• Versatility – Single and double flaring in one kit
• Complete Set – Includes tube cutter for full tube preparation

Single vs. Double Flares:

Single Flare (45°)

Standard flare type used in HVAC/R refrigerant lines and low-pressure applications. The 45° angle creates a metal-to-metal seal when compressed by a flare nut. This kit flares 7 metric sizes: 4, 6, 8, 10, 12, 15 and 16mm O.D.

Double Flare (Inverted Flare)

Required for high-pressure applications such as automotive brake lines and hydraulic systems. The double-wall construction provides superior strength and resistance to vibration and pressure cycling. Includes adapters for 4.75, 5, 6, 8 and 10mm O.D. tubing.

Metric Tubing Applications:

Metric tubing is standard in European and Asian HVAC/R equipment, modern automotive systems, and international plumbing applications. This metric tool set ensures proper flare dimensions for metric tube sizes, preventing leaks and ensuring system integrity.

Operating Instructions:

For cutting: Position tube in cutter, tighten cutting wheel gradually whilst rotating cutter around tube. For single flaring: Clamp tube in flaring tool at correct height for tube size, position flaring cone, and tighten to form 45° flare. For double flaring: Use appropriate double flaring adapter to form initial flare, then complete with flaring cone. Inspect flares for cracks, splits, or irregularities before assembly.

Maintenance:

Keep flaring tools clean and free from metal shavings. Lubricate moving parts occasionally. Replace cutting wheel when dull. Store tools in protective case to prevent damage. Inspect flaring cones for wear or damage. Clean tube ends thoroughly before flaring to prevent contamination.

Complete professional metric flaring and cutting tool set for 45° single flares (4-16mm) and double flares (4.75-10mm). Includes heavy-duty tube cutter. Essential for HVAC/R, automotive, and plumbing metric tube work.
