3M Heat Shrink Tubing 12 in Black 1.1 in ID PK10

SKU CH-8FQ1-S14ST

Heavy-wall adhesive-lined tubing shrinks 3:1 from 1.1 in to .37 in to seal 2 AWG–4/0 AWG wires in a 10-piece pack

  • Heavy-wall protection for 2 AWG to 4/0 AWG cables
  • Adhesive-lined 3:1 shrink creates water-resistant seal
  • Cross-linked polyolefin resists abrasion, acid, alkali and UV
  • Operates from -67 °F to 230 °F
  • Ten 12-inch black pieces ready for field use

Heavy-wall shrink tubing for large conductors

This 3M heat-shrink tubing is built for electricians and maintenance technicians who need to seal and protect heavy-gauge wire. Each piece starts at a 1.1 in inside diameter and shrinks to 0.37 in, covering wire sizes from 2 AWG up to 4/0 AWG. The pack contains ten 12 in lengths ready for individual use.

Cross-linked polyolefin with adhesive lining

The rigid, cross-linked polyolefin wall thickens to 0.12 in after shrinking, forming a durable barrier that resists abrasion, acids, alkalis and UV exposure. An inner adhesive layer flows during heating to create a watertight seal around the connection. Individual pieces allow precise cutting and placement on site.

Rated from -67 to 230 degrees F

The tubing maintains its protective properties across a wide temperature span, staying flexible in extreme cold and stable in high heat. No flame-retardant rating is claimed, so installers should verify local code requirements for fire-sensitive areas. The heavy wall and adhesive combine to deliver long-term environmental sealing in normal service.

Questions about this item

What shrink ratio does the 3M tubing deliver, and what final inside diameter does that produce?

The tubing shrinks at a 3:1 ratio, taking the 1.1 in starting inside diameter down to 0.37 in after heating.

What are the piece length and quantity needed to cover a repair?

Each piece is 12 in long and the pack contains 10 individual pieces.

How do you apply the adhesive-lined tubing, and what step is often missed?

Slide the tubing over the splice, then heat evenly until the adhesive flows and the wall reaches 0.12 in thickness; the missed step is continuing heat until the inner adhesive fully melts and seals.
