Electricians, Datacom and Telecom professionals, Railroad and Avionics technicians need reliable, durable, and permanent ways to mark their important wires. LABELWORKS PX Heat Shrink Tube is an excellent solution for these industries. Print right on the tube then slide over the desired wire (non-terminated ends work best) and shrink using a heat tool for a snug fit. Leave un-shrunk for moveable sheets, or shrink around multiple wires for optimum organization.This Epson LABELWORKS PX Shrink Tube (EDMO# 208YLBYPX) is 1/4 x 98-inch, black text on yellow tape, and can be used on 6–18 AWG wire.
