10. Frequently Asked Technical Questions (FAQ)

Expert FAQ: R134a Refrigerant Charging Hoses

Q1. What is the internal material structure of a high-quality R134a refrigerant hose?
A: It's typically a synthetic rubber (NBR/CR/EPDM) core, multi-ply polyester fiber braid, and a flexible, oil/UV-resistant cover. This structure ensures low permeation and durability.
Q2. What certifications are required for automotive AC hoses?
A: Leading hoses comply with ISO/TS16949 and SAE J2064 (Type C or E), attesting to burst strength, chemical compatibility, and permeation control.
Q3. How long is the service life of a standard R134a hose in the field?
A: 5–10 years in auto AC, up to 12+ years in less aggressive industrial conditions. Many pass 100,000+ pressure cycles (ISO/SAE test basis).
Q4. What is the standard installation fitting or thread for R134a charging hoses?
A: SAE 1/4" female, SAE M14 x 1.5, and 1/2" ACME are the most common (per SAE J2196/ISO 5176). Custom threads available on request.
Q5. How is leak resistance tested in production?
A: Every batch is robotically leak-tested under 35 Bar working pressure and 140 Bar burst (per SAE J2064); helium immersion or nitrogen pressurization is often used for QA.
Q6. Are hoses color-coded for refrigerant identification?
A: Yes, color-coding (blue for low, red for high, yellow for service) is standard in r134a recharge hose with gauge sets and ac manifold gauge set r134a applications.
Q7. What is the MOQ and delivery time for custom hoses?
A: MOQ starts from 100 meters (customized), delivery typically within 7-15 days as confirmed by our logistics records and customer experience.
