It is a premium, ultra-high-temperature insulated metal hose designed for the most rigorous laboratory and pilot plant thermoregulation requirements. Featuring a nominal width of NW12 and robust M24x1.5 threaded connections, this flexible tubing is engineered to handle extreme thermal environments, supporting an expansive working temperature range from -100°C up to 350°C. This exceptional range makes it an essential accessory for high-temperature reactors, autoclaves, and distillation units where standard hoses would fail. At 100cm (1 meter) in length, it provides a compact, high-efficiency connection that minimizes "dead volume" and heat loss between the circulator and the application. The hose is constructed from high-grade 1.4404 stainless steel and features advanced multi-layer thermal insulation protected by a smooth, wipe-clean silicone outer jacket and safety end caps.
