1-1/2" Single Wall Heat Shrink Black

ST112-4

$4.70

| /

1-1/2" black single-wall polyolefin heat shrink with a 2:1 ratio, sized to cover approximately 4/0 AWG to 350 kcmil cable and lugs. Flame retardant; UL Listed and CSA Certified.

Use it for: insulating and strain-relieving lug barrels, bundling cable ends, and abrasion protection on battery and welding cable.

Choose something else if: the connection needs to be waterproof — single-wall tubing is not sealed; use adhesive-lined dual wall heat shrink. Pick a size that slides over the lug or connector before shrinking and grips the cable after.

Available in 6in and 4ft lengths or an 82ft spool. See all single wall heat shrink.
