12mm Heat Shrink Sleeve Tube, Red (1 Meter)

Stepping up from the thinner 10mm heat shrink tube already covered in the catalog, this 12mm red tubing gives a slightly larger bore for insulating bulkier wire splices, connector bodies, or small cable bundles that a thinner tube wouldn't comfortably fit over. The red color doubles as a simple wire-identification system, letting a builder mark a specific positive line or signal run at a glance once the tube is shrunk down and the joint is finished, rather than relying only on black or the bare wire color underneath.
