• Damaged hose connections at the P-nut and springlock ends
• Corrosion or wear at the original discharge line assembly
• Improper sealing at the A/C hose connection points

Installation Notes and Tips

Verify refrigerant type, hose routing, and connection style before installation. This hose uses a P-nut fitting on the discharge end and a male springlock on the suction end, so matching the original configuration is important for proper fitment. Replace the included gasket or seal during installation and inspect adjacent A/C components for contamination, wear, or damage before recharging the system.
