Heat shrink tubing, available in 2:1 and 3:1 shrink ratios with or without adhesive, is a versatile solution for electrical and mechanical applications. The 2:1 tubing shrinks to half its original diameter, providing reliable insulation, abrasion resistance, and cable bundling for electrical wiring, electronics, and telecommunications. The 3:1 variant, shrinking to one-third its size, accommodates irregularly shaped components, ensuring a secure fit. Adhesive-lined tubing enhances environmental sealing, protecting against moisture, dust, and chemicals, making it ideal for outdoor, automotive, and marine environments. Applications include insulating splices, protecting wire harnesses, strain relief, and organizing cabling, ensuring durability and safety in professional installations. Most items come with free shipping and some with volume discounts. Thank you for your business and support.
