Heavy Duty Heat Shrink Tubing

Protect with heavy duty tubing

When an application requires more robust protection, heavy duty heat-shrinkable tubing is the cost-effective solution for optimizing insulation and protection.

When an application requires more robust protection, heavy duty heat shrink tubing provides cost-effective solutions.  Heavy duty tubing offers toughness, durability, excellent insulation, abrasion protection, mechanical abuse reliability, and resistance to chemicals, moisture and oils when industry standards require rugged tubings. The thick-wall insulates and protects. Benefits of this type of tubing include controlled amounts of adhesive and consistent results; compliance with AMS-DTL-23053 standards and multiple products offered in flame-retardant (FR) versions.
