Why Red?

Industry-standard colour coding uses red hoses for the high-pressure (discharge) side of refrigeration systems. This prevents accidental connection to the wrong service port and ensures safe, correct operation.

Maintenance:

• Inspect hoses regularly for cracks, wear, or damage
• Replace hoses showing signs of deterioration
• Store coiled loosely to prevent kinking
• Keep fittings clean and free from debris
• Avoid exposure to sharp edges or hot surfaces

Professional Quality: Mastercool charging hoses are built to professional standards for daily use in demanding HVAC/R service environments.
