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 a wide range of modern vehicle AC systems.

Q: How does KEMO ensure the quality of automotive rubber products?

We employ technical engineers from world-leading companies like Goodyear and Parker and collaborate with top research institutions to provide rigorous testing reports and performance validation.

Q: What is the advantage of "low permeability" in AC hoses?

Low permeability ensures that the refrigerant stays inside the system longer, maintaining optimal cooling performance and reducing the frequency of costly refrigerant refills.

Q: Can you provide customized sizes or specific technical specifications?

Yes, KEMO offers comprehensive OEM and ODM services. We can design and develop products based on your specific I.D, O.D, and pressure requirements.

Q: How is the A20 hose protected against engine bay environments?

The hose is engineered with ozone resistance and aging resistance, preventing the rubber from becoming brittle or cracking due to high heat and chemical exposure.

Q: What packaging options are available for bulk orders?

We offer multiple options including transparent PVC film, color woven bags, standard cartons, pallet packing, and spool packing to meet your logistical needs.
