RS PRO White Ceramic Bead 4.5mm Bore 1200 °C

It has a bore size of 4.5 mm and comes in a quantity sufficient to cover 3.5 m of wire. With a steatite Ker 220 construction, it's resistant to abrasion and humidity and has a maximum operating temperature of +1200°C. It has a convenient fish-spine design, so you can interlock multiple beads to provide flexible insulation around wires.

This ceramic bead is safe and suitable for use in industrial settings with high-voltage and high-temperature wiring needs. You can use it for insulating wires that run close to a heatsink, or for applications such as air and vacuum systems, 3D printers and insulation for electrodes and curved wires.
