Heat Shrink Tubing for Electrical Applications
Protect wires, cables, and connections from moisture, dust, and abrasion. BABSCO stocks heat shrink tubing for electrical work across many industries. Order online, or ask us for sizes we haven’t listed yet.

What Is Heat Shrink Tubing?
Heat shrink tubing is a plastic tube that shrinks tightly around wires and cables when heated. It insulates and protects them from moisture, dust, and physical wear.
Without it, exposed connections can lead to short circuits, equipment failures, and costly repairs. Larger tubing also bundles cables together, making routing cleaner and easier to manage.
Benefits of Heat Shrink Tubing
Protection from the elements
Shields against abrasion, oil, chemicals, and other contaminants.
Added insulation
Forms a tight fit that prevents movement and deterioration, keeping connections secure.
Strain relief
Reduces strain on cables, especially in tight spaces, extending component life.
Cleaner cable management
Bundles wires neatly for an organized, efficient layout.
Common Heat Shrink Materials
Each material suits different conditions. Here’s how the most common options compare.
Polyolefin
The most widely used option. Resists high temperatures and chemicals, making it versatile for most electrical work.
PVC
Durable and abrasion-resistant for low-temperature applications. Available in many colors and flame-retardant versions.
Elastomer
Built for industrial use, with resistance to caustic fluids and harsh environments.
PVDF
Polyvinylidene fluoride: strong and resistant to flames, chemicals, and industrial fluids for demanding environments.
Frequently Asked Questions
How do I choose the right size?
Pick tubing whose expanded inside diameter fits over the largest part you’re covering, and whose shrunk diameter is smaller than the narrowest part, so it grips tightly once heated. If you’re unsure, contact us and we’ll help you choose.
Which material should I use?
Polyolefin covers most general electrical work. PVC suits low-temperature jobs, elastomer handles harsh fluids, and PVDF is for high-heat or chemical-heavy environments.
