Installation Guide
| Step | Operation | Technical Details |
|---|---|---|
| 1 | Cut & Deburr | Cut the tube squarely at a 90-degree angle. Important: Deburr the tube end thoroughly to avoid scratching the ferrule. |
| 2 | Assemble Components | Slide the nut onto the tube first, followed by the ferrule. *Note: The tapered end of the ferrule must face toward the tube end. |
| 3 | Positioning | Push the tube into the coupling body until it reaches the internal stop lip (stop point). Hold firmly. |
| 4 | Tightening | Hand-tighten the nut until snug. Use a wrench to tighten an additional about 1 – 1.5 turns (or until it feels tight). |
