Working Pressure Ranges:
Temperature and type of tubing used are important factors, the following table is a good guide for proper selection. The PSI rating given is based on a temperature of 73°F using copper tubing.
| PSI | Tube OD | Tube Wall |
| 1400 | 1/4" | .030 |
| 1000 | 3/8" | .032 |
| 750 | 1/2" | .032 |
| 650 | 5/8" | .035 |
| 550 | 3/4" | .035 |
Assembly Instructions:
- Cut tubing squarely and clean tube end thoroughly to remove burrs.
- Place nut onto tube. Place threaded end of nut toward end of tube.
- Flare tube end with flaring tool to provide 45° flare. (flare tools are available, please contact the factory for pricing and availability)
- Clamp tube flare between nut and nose of fitting body by screwing nut on finger-tight. Tighten with a wrench an additional 1/4 turn for a metal-to-metal seal.
