Ac Refrigerant Hose For Car

The AC Refrigerant Hose for Car is the flexible tubing that connects the compressor, condenser, evaporator, and expansion valve in the automotive A/C system. It transports gaseous or liquid refrigerant (R134a, R1234yf) throughout the system. The AC Refrigerant Hose for Car must work reliably under high temperature, high pressure, and vibration over the long term. It must also have extremely low refrigerant permeation to maintain system charge and cooling efficiency. This hose determines whether the A/C cools "effectively," whether system pressure "stays stable," and whether refrigerant "leaks slowly." In simple terms, it keeps the A/C "cooling fast" and summer driving "comfortable."

Anhui Denaifu has over 22 years of experience in A/C hose manufacturing. Our 127,000+ square meter facility employs over 80 people. Our AC Refrigerant Hose for Car covers 80% of vehicle brands in China through tier-1 suppliers.

Our AC Refrigerant Hose for Car features a three-layer construction: inner rubber layer, reinforcement layer, and outer rubber layer. The inner layer uses refrigerant-resistant rubber, compatible with PAG or POE oils. The reinforcement layer uses high-strength polyester or aramid fiber braid for pressure resistance. The outer layer is ozone-resistant, weather-resistant, and abrasion-resistant for the harsh engine bay environment. The surface is clean with no oil, scratches, damage, or bubbles. Unspecified dimensions follow 3D model data. Unspecified tolerances follow GB/T 3672.1-2003 M4. Hardness is Shore A 60±5. Burning characteristics meet GB 8410-2006 (burn rate ≤100 mm/min). Odor rating is <3.0. VOC and restricted substance levels meet relevant standards.
