Installation/Set-Up Challenges for SAE 45 Degree Flare Fittings

Common installation or setup challenges when using SAE 45 Degree Flare Fittings include:

1. Improper Flare Angle: The flare angle must be precisely 45 degrees to ensure a proper seal. Deviations from this angle can lead to leaks and improper fitting connections.

2. Flare Depth: Ensuring the correct flare depth is crucial. Flares that are too shallow or too deep can cause leaks or fitting failure.

3. Debris and Contaminants: Any debris or contaminants present on the flaring tool, tubing, or fittings can interfere with the sealing surfaces, leading to leaks.

4. Incorrect Tube Cutting: Using improper cutting tools or techniques can result in uneven tube ends, making it difficult to create a proper flare and causing leakage issues.

5. Over-tightening: Excessive tightening of the flare nut can distort the flare and tubing, compromising the seal and potentially causing leaks.

6. Under-tightening: Failing to tighten the flare nut sufficiently can also lead to leaks. It's essential to follow the recommended torque values for tightening.

7. Use of Incorrect Tools: Using the wrong tools for flaring can result in improperly formed flares, leading to leaks and fitting failure.

8. Tube End Preparation: Inadequate tube end preparation, such as burrs or rough edges, can hinder the proper seating of the flare fitting, potentially causing leaks.

To mitigate these challenges, it is crucial to follow manufacturer guidelines, use calibrated tools, inspect components for cleanliness, and ensure proper technique and torque values are used during installation.
