Vulcanized Hard Fiber Tube, 1.75" (45mm) OD x .125" (3mm) Wall x 6"

Tube of hard fiber (also known as vulcanized fiber). Hard fiber is made from cotton fabric which is chemically treated to yield a dense, bone-like substance with excellent tensile strength and good electrical insulation properties.

Hard fiber is also available in electrical-grade sheets ("fishpaper"), and rod shapes. We can supply rods or tubes in custom sizes (please inquire).
