Product Description


QDDHN-LD®️  A/C hoses are engineered to OE design and specifications, ensuring an accurate and lasting installation. Duplication of OE routing, constructed with high-quality materials and use of safety features protects against premature failure.


We design every A/C component to the most stringent standards in the industry, with energy-efficient, environmentally safe air conditioning hose and coupling solutions built to resist heat, moisture, and ozone corrosives to maximize the system longevity. 


Hose Construction: 

Usually, A/C hose has four layers. Inside the tube is nylon (PA), the middle layer is EPDM or IIR (Isobutylene-Isoprene Rubber), the reinforced layer is PET or single high strengthen weaving fiber braided. The outer tube is EPDM with a black and smooth cover.
