Frequently Asked
Questions

Expert answers to common technical and commercial inquiries regarding AC lines.

01

How do I specify a custom order for AC lines?

You can provide your original OEM part numbers, detailed CAD drawings, or physical samples. We recommend specifying the fitting sizes, total length, and the intended refrigerant type (e.g., R134a, R1234yf) for custom car ac lines.

02

What makes your rubber compounds superior to generic hoses?

Our compounds are engineered with high-density polymers that provide superior ozone and thermal resistance, preventing the common "cracking" seen in low-grade rubber under engine heat.

03

Do you support high-pressure R1234yf systems?

Yes, we specialize in modern R1234yf compatible lines, designed to handle the specific pressure profiles and chemical properties of newer, eco-friendly refrigerants.

04

What is the typical lead time for custom prototype samples?

Our rapid prototyping cycle allows us to deliver precision samples within 7 business days from the final design approval.

05

How do you ensure zero-leakage at the crimp points?

We use computer-controlled crimping machines that apply precise force based on the hose wall thickness and fitting material, followed by a 100% vacuum or pressure leak test.

06

Are your AC lines compatible with different fitting standards?

Yes, we provide a full range of fitting options including SAE, JIC, DIN, and various metric standards to ensure compatibility with global vehicle architectures.
