Barrier Automotive AC Hose Assembly R134a Nylon Inner Tube with Crimped Aluminum Fittings 3000 PSI Burst

The WNRLN BH-3000 is a professional-grade barrier-type automotive AC hose assembly engineered for R134a and R404A mobile air conditioning systems. This assembly integrates a high-performance nylon inner tube barrier layer that virtually eliminates refrigerant permeation, a common failure point in conventional rubber-only hoses. Each hose is factory-crimped with precision aluminum alloy end fittings, delivering a ready-to-install solution that meets or exceeds SAE J2064 Type E specifications. Designed for both OEM replacement and aftermarket garage applications, this hose assembly is suitable for use in passenger cars, light trucks, and compact commercial vehicles where reliable refrigerant containment is critical for system performance and environmental compliance.

The nylon inner barrier tube is co-extruded with a synthetic rubber outer cover, providing exceptional resistance to high-temperature compressor discharge gases while maintaining the flexibility required for tight engine bay routing. The outer cover is formulated with UV and ozone inhibitors, extending service life even under prolonged hood-down exposure. The crimped aluminum fittings are manufactured from corrosion-resistant 6061-T6 aluminum alloy, precision-bored to maintain exact inner diameter tolerances. Each fitting undergoes a 100% helium leak test at the factory prior to final crimping, ensuring zero-leak performance from day one. With a rated burst pressure of 3000 PSI and a maximum working pressure of 500 PSI, this hose assembly delivers the safety margins required by professional automotive technicians and fleet maintenance operations.

• Nylon Inner Barrier Tube: Co-extruded nylon layer prevents R134a refrigerant permeation, achieving permeation rates below SAE J2064 limits for enhanced system longevity and environmental protection.
• Crimped Aluminum Alloy Fittings: 6061-T6 aluminum end fittings with precision crimped connections provide a leak-proof mechanical seal that withstands vibration and thermal cycling in engine bay environments.
• 3000 PSI Burst Pressure Rating: Engineered with a 6:1 safety factor over maximum working pressure, offering reliable burst protection for demanding automotive AC applications and high-side discharge lines.
• R134a and R404A Compatible: Universal refrigerant compatibility covers both legacy R134a systems and newer R404A installations, making it suitable for mixed-fleet maintenance and retrofitting projects.
• UV and Ozone Resistant Cover: The synthetic rubber outer layer is fortified with UV stabilizers and antiozonants, preventing premature cracking or degradation during extended outdoor vehicle operation.
• Helium Leak Tested at Factory: Each assembled hose undergoes a 100% helium mass spectrometer leak test, detecting micro-leaks as small as 1x10^-6 mbar L/s before packaging and shipment.
• Wide Temperature Operating Range: Rated for continuous operation from -30 C to +125 C, ensuring reliable performance in extreme climate conditions from Scandinavian winters to Middle Eastern summers.

This barrier AC hose assembly is purpose-built for the automotive aftermarket and light commercial vehicle segments. Ideal applications include passenger car AC suction and discharge line replacement on Toyota, Honda, Nissan, Hyundai, and Ford platforms from model years 2005 to 2025. The crimped aluminum fittings support direct bolt-on installation to standard O-ring and flare-type compressor, condenser, and evaporator connections. Fleet maintenance shops will appreciate the ready-to-install configuration that eliminates the need for on-site crimping tools or specialized hose assembly equipment. The assembly is also suitable for agricultural and construction equipment where compact AC hose routing and reliable refrigerant containment are required in dusty, high-vibration operating environments. Custom lengths, fitting configurations, and angled end orientations are available upon request for specialized vehicle platforms or non-standard AC system layouts.

Each barrier AC hose assembly is individually packaged in a protective PE sleeve with moisture-absorbing desiccant to prevent fitting corrosion during storage and transit. Master cartons are constructed from export-grade double-wall corrugated cardboard with internal foam dividers that isolate each hose assembly from adjacent units, preventing fitting damage from contact during shipping. Every production batch undergoes statistical process control (SPC) monitoring with detailed quality records maintained for traceability. Our ISO 9001:2015 certified quality management system ensures consistent adherence to dimensional tolerances, crimp integrity standards, and leak-test pass rates. We offer a 12-month warranty against manufacturing defects and provide full technical support including installation guidance and compatibility verification. Samples are available for evaluation prior to bulk ordering, and OEM/ODM custom branding options are supported for volume buyers seeking private-label solutions.
