Vulcanized fiber tube is manufactured by winding zinc chloride treated paper on making mandrel to the predetermined wall thickness. They are then going through pouring, drying, rolling, grinding, and sanding processes to get desired inside and outside diameters.
Vulcanized fiber tube has a density of around 1.40 g/cm³. It has good physical properties, mechanical properties, dielectric strength, arc resistance, and arc-quenching characteristics. Because of its excellent machinability, vulcanized fiber tubes can be sanded, knurled, spirally cut, threaded, lathed, and easily fabricated to various products. The major applications of vulcanized fiber tubes are fuse cartridges, high voltage cutout fuse liners, lightning arresters, grommets, insulators, and bushings.

Vulcanized Fibre tube is moisture conditioned and then rolled under pressure to finish inside diameter and oversized outside diameter. The outside diameter is then finished, ground to size, and buffer. The outside diameter can also be knurled or skived for use in filament wound finishing for fuse tube applications.
