Imperial 437FB Flaring Tool for 3/16" to 5/8" Copper, Aluminum & Brass Tubing

The Imperial 437FB is a professional-grade flaring tool designed for creating precise 37-degree flares on soft copper, aluminum, and brass tubing. This tool features a hardened steel, chrome-finished cone that produces exceptionally smooth, high-strength flares with a radius at the base rather than the sharp angle formed by ordinary flaring tools, resulting in stronger, more reliable connections.

Key Features:

• Self-Gauging Design: Simply insert the tube flush with the top of the die for accurate flare size every time
• Engineered Chamfer: Creates a smooth, even radius at the base of every flare for superior strength and leak prevention
• Slip-On Yoke: Permits use in tight quarters and allows flaring where there is minimal space between the nut and tube end
• Smooth Feed Screw: Provides easier operation and more controlled flaring action
• Positive Tube Gripping: Sliding die blocks lock securely in place with clamp action for precise tube positioning
• Durable Construction: Features satin chrome and black finish for long-lasting performance

Compatible Tubing Sizes:

• 3/16" OD (0.032" wall thickness)
• 1/4" OD (0.032" wall thickness)
• 5/16" OD (0.032" wall thickness)
• 3/8" OD (0.032" wall thickness)
• 1/2" OD (0.035" wall thickness)
• 5/8" OD (0.049" wall thickness)

Ideal for HVAC, refrigeration, automotive, and plumbing applications where professional-quality flares are essential for safe, leak-free connections.
