Frequently Asked Questions

Q: Which refrigerants are compatible with the A20 A/C Hose?

The A20 A/C Hose is fully compatible with R134a, R404a, and the newer R1234yf refrigerants, making it suitable for both older and modern vehicle AC systems.

Q: How does "pulse-resistance" benefit the automotive AC system?

Pulse-resistance allows the hose to absorb the rapid pressure spikes created by the compressor, preventing fatigue cracks and extending the overall life of the hose.

Q: Can KEMO provide custom sizes for specific vehicle models?

Yes, we provide full OEM and ODM services. We can design and develop hoses based on your specific technical drawings and provide the necessary testing reports.

Q: What makes KEMO hoses superior to standard rubber alternatives?

Our hoses are developed by engineers from industry giants like Goodyear and Parker, featuring lower permeability and higher resistance to ozone and aging.

Q: What packaging options are available for bulk orders?

We offer five flexible options: transparent PVC film, color woven bags, pallet packing, carton packing, and spool packing to suit your logistical needs.

Q: How is the quality of the rubber automotive hoses verified?

Every product undergoes rigorous testing for burst pressure, permeability, and material aging in collaboration with top research institutions in China.
