What is a 45° Flare?

A 45° flare (also called SAE flare) is the industry-standard connection method for refrigeration and air conditioning systems. The flared end of the tube creates a metal-to-metal seal when compressed by a flare nut, providing a leak-free connection that can withstand high pressures and temperature extremes.

How to Use:

1. Cut tube to length and deburr inside and outside edges
2. Slide flare nut onto tube (before flaring!)
3. Insert tube into appropriate size hole in yoke
4. Adjust tube height so it's flush with top of yoke
5. Position auto-centering cone over tube
6. Turn handle clockwise to create flare
7. Continue until flare reaches edge of yoke
8. Remove cone and check flare quality

Perfect Flares Every Time:

• Auto-Centering – Cone automatically centres on tube
• Bearing-Driven – Smooth, consistent pressure
• Forged Steel – Won't flex or distort under pressure
• Precise Sizing – Each hole machined to exact specifications

Maintenance:

• Keep yoke and cone clean and free from debris
• Lubricate cone threads occasionally with light oil
• Store in dry location to prevent rust
• Inspect cone for wear or damage regularly
• Replace if cone becomes worn or damaged
