Introduction

Bending AC tubing is a critical task in HVAC installations that requires precision and care. Improper bending can lead to kinking, damaging the tubing and compromising the system's efficiency. This article provides a detailed guide on how to bend AC tubing properly.

Importance of Proper Tubing Bend

Proper bending maintains the internal diameter of the tubing, ensuring adequate refrigerant flow and system performance. A kinked tube can lead to increased energy consumption and potential system failure.

Parameters for Effective Bending

Key parameters for bending AC tubing without kinking include:

• Tubing Material: Copper is preferred due to its malleability.
• Bend Radius: Minimum bend radius should be at least 3× the tubing diameter to prevent kinks.
• Temperature: Bending is more manageable when the tubing is slightly warm.
• Lubrication: Use a bending lubricant to reduce friction.

Step-by-Step Guide to Bending AC Tubing

1. Measure the required length and mark the bending point on the tubing.
2. Clamp the tubing in a tube bender at the marked point.
3. Slowly bend the tubing, applying constant pressure until achieving the desired angle.
4. Check for any signs of flattening or kinks.
5. Adjust as necessary to maintain the tubing's round shape.
