Four Seasons Hose Assembly Product Line Details

The Four Seasons Hose Assembly product line focuses on providing complete hose and pipe solutions for automotive HVAC systems. This line emphasizes quality materials and precise fitment to maintain system integrity and performance. The 66053 hose assembly is part of this line, offering a combined discharge and suction line with integrated components such as mufflers and manifold blocks to meet OEM specifications.

Detailed Product Description

The 66053 hose assembly is engineered with aluminum and rubber to withstand the pressures and temperatures typical in automotive air conditioning systems. It supports both R134a and R1234yf refrigerants, making it suitable for vehicles updated to newer refrigerant standards. The assembly includes two sets of slimline washer O-rings (part numbers 24402 and 24404) to ensure leak-free connections at both ends. The discharge and suction ends utilize P-nut fittings for secure attachment, and the assembly comes without a service port or bracket, designed for direct replacement applications. Additionally, the integrated muffler helps reduce noise generated during system operation.
