Why Choose Dunbar Heat Shrink Tubing?
Dunbar has built a strong reputation for manufacturing heat shrink tubing that meets rigorous performance standards. Their products are engineered to deliver consistent shrink ratios, strong mechanical protection, and lasting durability in demanding environments. Dunbar heat shrink tubing is available in a range of materials, wall thicknesses, and configurations to accommodate a wide variety of installation requirements.
One of the most popular products in the Dunbar lineup is the Dunbar 1635F, a dual wall heat shrink tubing that features an inner adhesive liner. The adhesive liner activates during the shrink process, creating a strong environmental seal around connections, splices, and terminations. This makes the 1635F an ideal choice for applications where moisture resistance and mechanical strain relief are critical.
Beyond raw performance, Dunbar products are designed for ease of installation. The tubing shrinks uniformly when heat is applied, ensuring a clean and professional finish across every application. Dunbar heat shrink tubing is also recognized for its compliance with military and industry specifications, making it a preferred choice in high stakes environments where reliability cannot be compromised.
