This lightweight and highly flexible hose is engineered to deliver reliable performance in demanding industrial cooling systems and automotive air conditioning applications, serving as an efficient alternative to traditional copper tubing. Designed for use with refrigerants such as R22, R134a, R404a, R407c, R410a, and R507, as well as POE and PAG compressor oils, it ensures safe and efficient operation during filling and testing processes. In sizes from 1/12" to 1/4", the hose is also suitable for CO₂ (R-744) transmission, meeting the challenge of pressures nearly ten times higher than those required by standard refrigerants. Its advanced construction features a durable polyamide inner layer, with a PA and TPE blend for smaller diameters, reinforced by a robust polyester braid for added strength. The outer layer, made of abrasion-resistant polyurethane with micro-perforation, guarantees long-lasting durability even under intensive use. With a working pressure range of 45 to 120 bar and an impressive operating temperature span from -45°C to +130°C (up to +70°C for water and air), this hose combines safety, flexibility, and resilience, making it the ideal choice for professionals seeking a dependable solution for modern cooling and refrigeration systems.
