Why 5/16" for R410A?

R410A systems operate at higher pressures than traditional refrigerants. The 5/16" tube size (with 1/2"-20 UNF fittings) is the industry standard for R410A refrigerant lines, providing the necessary flow capacity whilst maintaining system efficiency.

How to Use:

1. Slide the spring bender over the tube at the desired bend location
2. Position the bend point in the centre of the spring
3. Slowly bend the tube to the desired angle
4. The spring prevents kinking and maintains tube roundness
5. Remove the spring by rotating and pulling

Benefits of Spring Benders:

• Prevents Kinking – Maintains tube integrity during bending
• No Power Required – Simple, reliable hand tool
• Portable – Lightweight and easy to carry
• Precise Control – Feel the bend as you work
• Works Anywhere – No need for bench or vice
• Cost-Effective – Affordable alternative to hydraulic benders

Care & Maintenance:

• Keep spring clean and free from debris
• Store in dry location to prevent rust
• Inspect regularly for damage or deformation
• Replace if spring loses tension or becomes damaged
