Product Details

In an automotive air conditioning system, the suction hose carries refrigerant on the low-pressure side after it leaves the evaporator and returns to the compressor. This hose is used in 2008, 2009, 2010, 2011, and 2012 Nissan Sentra models, making it a focused replacement choice for Sentra A/C hose service. The 4811643 hose supports proper refrigerant flow in the low-side circuit and is built for the HVAC hose and pipe category.

Common Repair Uses

• Leaking or damaged low-side A/C hose
• Loss of refrigerant from cracked hose sections or fittings
• Poor A/C performance caused by restricted suction-side flow
• Service replacement during compressor or evaporator repairs

Installation Notes

Verify the vehicle year and Sentra application before installation. Recover refrigerant and evacuate the system before removing the existing hose, then inspect mating connections, seals, and adjacent HVAC components for wear or contamination. After installation, recharge the system to the correct specification and check for leaks.
