Our copper fittings are manufactured with a copper content of 99.9%, ensuring outstanding electrical and thermal conductivity for various heating and radiator applications.
Yes, they are highly durable and engineered to tolerate extreme pressure and temperature shifts. They maintain excellent structural stability and remain corrosion-resistant even in humid or harsh environments.
No, they feature a highly user-friendly design. Due to the high flexibility of the material, they can be quickly and easily installed and fixed via standard welding processes without complex tools.
These copper fittings are widely used in building systems (water supply, drainage, and heating), industrial manufacturing (chemical processing, hydraulics, and food/beverage), energy/refrigeration (HVAC, solar systems), and marine engineering.
Yes, we provide fittings complying with American Standards (ranging from 1/4" to 6-1/4" inches) as well as European Standards (ranging from 6mm to 159mm) to suit different international sizing requirements.
Due to their 99.9% copper content, they possess high thermal conductivity. This allows for extremely rapid heat transfer, significantly enhancing energy efficiency in evaporators, condensers, and solar heating platforms.
