Product Details

This suction hose is part number 4812780 and is intended for the compressor-to-evaporator side of the air conditioning system. In HVAC service, suction hoses carry low-pressure refrigerant vapor, so correct routing and sealing are important for stable cooling performance. This Global Parts hose matches the listed Toyota Highlander fitment and supports service work where the original low-side hose has leaked, cracked, or lost sealing integrity.

Common Repair Uses

• Low-side refrigerant leak at the hose assembly
• Cracked or deteriorated A/C hose material
• Loss of cabin cooling performance from refrigerant loss
• Service replacement after compressor or evaporator repair
• Restoring proper refrigerant flow in the Toyota Highlander A/C system

Installation Notes

Fits 2011-2013 Toyota Highlander. Verify hose routing, port alignment, and seal condition before installation. Recover refrigerant and evacuate the system according to proper A/C service procedures, then check for leaks after reassembly. Confirm the replacement matches the vehicle’s low-side hose configuration before charging the system.
