What is Hydraulic Crimping?

Hydraulic crimping creates permanent connections on soft copper refrigeration tubing by mechanically deforming the tubing around a fitting. This eliminates the need for brazing or soldering, making installations faster, cleaner, and safer. The hydraulic crimper applies controlled pressure through interchangeable die sets to create leak-free connections that meet industry standards.

Benefits of Crimping vs Brazing:

• No Heat Required – Safer, no fire risk or hot work permits
• Faster Installation – Crimping takes seconds vs minutes for brazing
• Cleaner Work – No flux residue or oxidation
• No Nitrogen Purge – Eliminates need for nitrogen during joining
• Consistent Quality – Hydraulic pressure ensures uniform connections
• Less Skill Required – Easier to train technicians
• Reduced Callbacks – Reliable, leak-free connections

How to Use:

1. Select correct die set for tubing size (12mm/5/8" for this model)
2. Install die set in hydraulic crimper
3. Cut tubing square and deburr
4. Insert fitting into tubing
5. Position crimper over connection point
6. Activate hydraulic pump to crimp
7. Release pressure and remove crimper
8. Verify crimp is complete and uniform

Colour Coding System:

Mastercool uses colour coding for quick die set identification:

• Purple – 6mm (5/16")
• Red – 8mm (13/32")
• Yellow – 10mm (1/2")
• Green – 12mm (5/8") – this model
• Black/Orange/Blue – Reduced barrier versions

Benefits:

• Fast Connections – Crimp in seconds vs minutes for brazing
• No Heat – Safer installations without fire risk
• Leak-Free – Hydraulic pressure ensures proper crimp
• Professional Quality – Meets industry standards
• Cost Effective – Reduces labour time and callbacks
• Easy Identification – Green colour coding for 5/8" size

Maintenance:

• Keep die sets clean and free from debris
• Inspect for wear or damage regularly
• Replace rubber strips when worn
• Store in protective case when not in use
• Lubricate moving parts occasionally

Professional Quality: Mastercool crimper die sets are built to professional standards for reliable, leak-free connections in demanding HVAC/R service environments. Part of the complete 71500 series hydraulic crimping system.
