The Sievert 2205 Ultragas Cartridge is a high-performance gas cartridge designed for professional blowtorch applications requiring intense heat. Featuring a specialist gas mixture of propane, butane and acetone, this cartridge delivers an exceptional flame temperature of 2,100°C, making it ideal for demanding tasks such as metal brazing, welding and heavy-duty plumbing work. The cartridge incorporates a foam insert that enables extended inverted use, providing greater flexibility when working in confined spaces or overhead positions. This feature is particularly valuable for plumbers and heating engineers working on pipework installations where standard positioning may not be practical. Safety is enhanced through a dual-layer self-sealing valve construction, providing additional protection during cartridge changes and storage. The 210g capacity offers substantial runtime for professional applications, whilst the self-sealing valve ensures compatibility with a wide range of Sievert blowtorch handpieces and other compliant torch systems.
