Our pipes are made of 99.9% pure copper, meeting ASTM B280 and C12200 standards. The insulation, constructed from 1/2" Polypropylene & UV Resistant material, ensures durability with a working temperature range from -40ºC to 120ºC.
Our refrigeration pipes come in sizes ranging from 1/4" to 1 1/8", with lengths available in 15m, 20m, 25m, 30m, and 50m. The pressure rating of our pipes is between 2100 to 7000 PSI, exceeding the required 700 PSI for R410, making them suitable for various air conditioning and refrigeration applications.
Moreover, our in-house produced insulation can be customized with your company name, size, and meters. The pipes are ideal for ductless mini-split systems, heat pumps, and centralized air ducted units, providing reliable performance for all your cooling needs.
