We offer our customers good quality Porcelain Square Threaded Tubes which are used for making RESISTORS,
Wire is wounded through these threads upon its entire length. These Porcelain Square threaded tube are of high dimensional accuracy and provide as excellent insulator for resistors.
We are currently manufacturing Square tube with Threads - 35, 45, 51, 59, 64, 68, 72, 79, 85 & 100 over its constant length.
