Detailed Product Description

The Four Seasons 55270 A/C refrigerant suction hose is engineered to handle low-pressure refrigerant flow within the Toyota Sequoia's air conditioning system. Made from a combination of aluminum and rubber, this hose assembly offers durability and flexibility where needed. The flange end and captured o-ring end provide secure, leak-resistant connections, while the included gasket and fittings simplify installation. This hose is designed without a service port or muffler, focusing solely on the suction line function. The three included green o-rings (part number 24682) ensure a tight seal, preventing refrigerant leaks and maintaining system integrity.

Common Applications and Issues Addressed

• Replacement of worn or damaged A/C refrigerant suction hoses in Toyota Sequoia models
• Resolving low refrigerant pressure issues caused by leaks or hose deterioration
• Eliminating refrigerant leaks at connection points due to faulty seals or o-rings
• Restoring proper refrigerant flow for efficient air conditioning performance
• Addressing hose assembly failures that lead to system pressure drops

Installation Notes and Tips

When installing the Four Seasons Hose Assembly 55270, ensure all old hoses and seals are fully removed to prevent contamination. Use the included gasket and fittings for a secure connection, and verify that the three green o-rings are properly seated to avoid leaks. Since this hose does not include a bracket or muffler, confirm that the existing mounting points on the Toyota Sequoia are intact and secure. Proper torque on the flange and P-nut fittings is essential to maintain system pressure and prevent refrigerant loss.
