9. Professional FAQ: Key Terms & Technical Insights
Frequently Asked Technical Questions
Q1: What is the main material used in air conditioner hose construction?
A: High-quality EPDM or NBR synthetic rubber, often reinforced with high-tensile PET or PA yarn and a proprietary gas barrier to ensure minimal R134a/R1234yf refrigerant permeation.
Q2: Which international standards apply to air condition hoses?
A: SAE J2064 (for automotive), ISO 9001/14001 (quality/environment), FDA/EN 378 (food & refrigeration), and REACH/ROHS compliance for environmental safety.
Q3: What is the typical working pressure and temperature range?
A: Working pressure varies from 20–38 bar, with temperature tolerance from -40°C to +130°C for high-performance air con hose.
Q4: What is "burst pressure" in auto brake hose and airconditioning hose specs?
A: Burst pressure is the maximum internal pressure the hose withstands before rupture, typically >3x working pressure (ISO & SAE standards).
Q5: How is hose flexibility measured?
A: By the minimum bend radius (multiple of hose OD) at a specified temperature without kinking or cracking, per ASTM D380.
Q6: Can air conditioner hoses be safely used for refrigerant gases like R1234yf?
A: Yes, modern hoses employ chemical-resistant materials and multilayer barriers, tested for compatibility with R134a, R1234yf, CO2, and traditional refrigerants.
Q7: What is the recommended installation torque for end fittings?
A: Installation torque and assembly follow manufacturer specs; for crimped ends, strict ISO 6841 or equivalent should be observed, and every joint should be leak-tested at 1.5x working pressure.
