3/16" Heat Shrink Tubing Set, (8) (DUB939)

Eight-piece 3/16-inch heat shrink tubing set, with four red and four black tubes, each 1.5 inches long. It’s designed to simplify wiring by color-coding positive and negative connections—red for positive and black for negative—and to shrink to about half its original size for a neat, secure fit.

Use it to insulate exposed leads and keep wiring tidy in electronics projects, with the red/black color pairing providing quick polarity identification and the shrink-to-fit feature delivering a clean, durable wrap.
