Product Details and Specifications

This A/C refrigerant discharge hose is constructed from a combination of aluminum and rubber, providing a balance of strength and flexibility necessary for high-pressure HVAC applications. It supports both R134a and R1234yf refrigerants, making it suitable for newer and older Honda Civic models. The hose assembly includes essential components such as gaskets and fittings, ensuring a secure and leak-free installation.

Installation Notes and Tips

When installing the Four Seasons Hose Assembly 66384, ensure the vehicle is compatible with the part by verifying the make and model as Honda Civic. Use the included gaskets and fittings to achieve a secure connection. The P-nut fitting on the suction end requires proper torque to avoid leaks. Note that the switch is not included, so if your system requires a switch, it must be sourced separately. Avoid using the hose assembly with incompatible refrigerants or systems exceeding specified pressure limits.
