Product detailed description
5-Layer Composite Reinforced Structure, Super High Pressure & Burst Resistance Different from cheap single-layer rubber hoses on the market, our AC air conditioning hose adopts standard five-layer integrated extrusion molding structure, each layer undertakes independent functional effects:
Inner sealing layer: Butyl rubber inner tube, ultra-tight molecular density, completely isolate refrigerant penetration, zero leakage of coolant gas, resistant to refrigerant corrosion;
Barrier isolation layer: Special nylon barrier layer, effectively prevent refrigerant molecular permeation, solve the problem of slow refrigerant loss of ordinary hoses for a long time;
Middle reinforced braided layer: High-strength polyester fiber braided net wrapped around the tube wall in all directions, greatly enhancing the tensile strength and pressure resistance of the pipeline, effectively avoiding pipe bulging, deformation and burst under instantaneous pressure surge;
Buffer rubber layer: Absorb pipeline vibration generated by compressor operation, reduce pipeline fatigue damage;
Outer protective layer: Weather-resistant EPDM outer rubber skin, resist sunlight ultraviolet radiation, rainwater erosion, engine high-temperature baking and oil splashing. The rated working pressure reaches 3.5MPa, burst pressure up to 12MPa, fully meet the high-pressure operation requirements of all automobile and household air conditioning systems.
Wide Compatibility With All Mainstream Refrigerants & Lubricating Oil This air conditioning pipeline has excellent chemical inertness, compatible with almost all commonly used refrigerants in the global refrigeration industry: R134a, R410A, R22, R407C, R1234yf and other coolants. Meanwhile, it can be well mixed with mineral oil, POE oil, PVE compressor lubricating oil, no chemical reaction will occur between the pipe wall and refrigeration oil, will not cause rubber swelling, softening or hardening embrittlement. It can be universally used for old and new air conditioning equipment without worrying about refrigerant model mismatch leading to pipeline damage.
Extreme Temperature Adaptability, No Cracking Under Cold & Hot Alternation The whole hose can work stably in the temperature range of -40℃ ~ +125℃. In winter low-temperature environment, the pipeline will not harden, stiff or brittle crack; under the high temperature baking of automobile engine compartment in summer, the outer rubber layer will not melt, soften or peel off. It perfectly adapts to the extreme temperature climate of tropical, frigid and temperate regions around the world, and maintains stable flexibility and sealing performance all year round.
Flexible & Easy Cutting Installation, Good Shock Absorption Performance The hose maintains moderate flexibility, can be freely bent and arranged according to the internal space layout of the vehicle or air conditioning unit, no rebound deformation after bending, convenient for technicians to lay pipelines in narrow gaps. The pipe body can be cut arbitrarily according to the required length with a professional pipe cutter, matched with standard AC pipe fittings, compression joints and manifold gauges on the market, easy to complete assembly and connection. In addition, the multi-layer structure can effectively buffer the vibration transmitted by the compressor during operation, reduce pipeline loosening caused by long-term vibration, and further avoid leakage risks at the joint.
Anti-Aging, UV & Oil Resistant Outer Rubber Surface The outer layer is made of high-performance EPDM weather-resistant rubber, added with anti-ultraviolet, anti-oxidation additives. Long-term outdoor exposed use will not appear rubber chalking, cracking, discoloration and aging; it also has excellent oil resistance, automobile engine oil, hydraulic oil splashed on the pipe surface will not corrode the outer wall, which is especially suitable for harsh under-hood working environment of various vehicles.

Hydraulic burst pressure test: Verify the maximum pressure bearing limit of the pipe body;
Air tightness leakage test: Fill high-pressure gas to check for tiny air leakage inside the pipeline;
Cold and hot alternating cycle aging test: Simulate seasonal temperature changes for long-term endurance inspection;
Refrigerant compatibility immersion test: Soak the hose in different refrigerants and lubricating oil to detect rubber stability;
UV weathering test: Simulate outdoor sunlight exposure to check anti-aging ability. All unqualified semi-finished products are eliminated to ensure each roll of hose has consistent reliable quality.
Wide Application Scenarios
Automotive Air Conditioning Maintenance: For sedans, SUVs, pickup trucks, vans, light commercial vehicles R134a/R1234yf car AC pipeline replacement, leakage repair, whole vehicle refrigeration pipeline renovation;
Household HVAC Field: Wall-mounted/floor-standing split air conditioners, inverter heat pumps, duct central air conditioning refrigerant connecting pipeline laying and replacement;
Commercial Refrigeration Equipment: Supermarket display freezers, catering cold storage, industrial chillers, refrigerated truck refrigeration system pipeline supporting;
HVAC Engineering Wholesale: Refrigeration contractors, auto parts distributors bulk stocking for daily maintenance and project supporting supply.
Practical Benefits After Replacement
Replacing aging, leaking original air conditioning pipelines with our reinforced AC hose can thoroughly solve refrigerant leakage, insufficient cooling effect and frequent air conditioning failures. Stable high-pressure sealing reduces repeated refrigerant filling costs; excellent anti-aging performance extends pipeline service life by more than 3 times compared with ordinary hoses; shock absorption structure protects the entire refrigeration system, avoiding compressor damage caused by pressure instability. With factory direct sales cost performance, it is the most trustworthy pipeline accessory for global refrigeration practitioners.
