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.

Heavy Duty Heat Shrink Tubing Portfolio
Insulation and Protection
-
BSTS/BSTS-FR Tubing
Made of a rugged polymer that resists moisture, fungus, and weathering, this tubing offers a 3:1 shrink ratio, thick-wall insulation, abrasion protection, and an FR-Flame-retardant option.
-
HF Tubing
High-flex, heavy-wall tubing developed for cable jacketing applications where cable flexibility is important. Offering 3:1 shrink ratio, it is flame-retardant.
-
HRHF/HRNF/HRSR Tubing
A high-ratio tubing that accommodates large differences between cables and cable connectors and backshells, which simplifies repair of damaged cables. Available in semirigid flame-retardant (SR), standard non-flame-retardant (NF), and high-flex flame-retardant (HF) options, its 5.6:1 shrink ratio offer toughness and durability.
-
RHW/RMW Tubing
RoHS compliant, this tubing (available in medium or heavy-wall) is designed for insulating, protecting, and a wide variety of low-voltage electrical applications. Available without adhesive, it has a 3:1 shrink ratio.
-
SST/SST-FR Tubing
This self-sealing dual wall tubing provides a simple, positive splice-sealing method that protects in extreme environmental conditions. RoHS compliant, with a 3:1 shrink ratio, it offers thick-wall insulation, strain relief. and abrasion protection. Available in a flame-retardant option.

Our heat shrink tubings are made of polyolefins, fluoropolymers, and elastomers enhanced by radiation crosslinking and heat-shrinkability. When heated during installation, our tubings shrink to conform to virtually any shape. These provide dependable insulation, mechanical protection, and strain relief, as well as aesthetic appeal. You can choose from tubings that are highly flexible or semi-rigid, designed for operation in high- or low-temperature environments. Includes halogen-free and flame-retardant products.
Heavy duty tubing products are intended for use in the most rugged environments.
