HeatShrink Tubing

Heat shrinkable tubing is a method of protecting and insulating various types of electrical interconnect assemblies and provide superior performance over standard methods such as taping or molding.

Heatshrink tubing is available in either single-wall or dual-wall constructions. When heated, the tubing shrinks and conforms to the size and shape of the underlying materials for a relatively simple and efficient installation. A wide range of standard and custom sizes, shrink ratios, colours and materials suit many applications and environments. Whether the application is for wire harnesses, cable assemblies, or busbar assemblies being used in aerospace, marine, energy or industrial environments, ALTA’s expertise can ensure the right product is selected for each customer’s specific application.

Single-wall tubing provides strain relief and protection against abrasion and mechanical abuse. Dual-wall tubing is used where corrosion protection and sealing are required; during installation an adhesive or inner lining melts and flows, creating a moisture-resistant barrier and seal.

Products meet and comply with many applicable industry standards and military specifications such as Mil-DTL-23053, Mil-R-46846 standards and are UL/CSA recognized.
