Sonoreboom 2-in-1 Braided Heat Shrink Sleeving 3/4" (19mm)

Sonoreboom 2-in-1 braided heat-shrink sleeving is a flexible fabric tube that halves its inner diameter when heated to tightly protect and neaten irregular hoses, cables and wiring.

This 22-foot roll of woven heat-shrink tubing comes as a durable, abrasion-resistant sleeve designed to conform to odd shapes and bundle components neatly. Before heat is applied the sleeve measures 3/4" (19mm) inner diameter and about 1-1/8" flat width; after shrinking it reduces to roughly 3/8" (9.5mm). The braided construction sheds moisture, allows heat to dissipate, and becomes stronger once shrunk, making it useful for automotive, marine, electronics, and workshop applications.

How does this braided shrink sleeve protect cables and hoses?

When heated evenly with a heat gun the braided fabric contracts and tightens around the object, creating a protective layer that resists abrasion while keeping bundles tidy. The woven strands thicken and lock together during shrinkage to improve impact and wear resistance without sacrificing flexibility.

• Tight woven strands increase abrasion resistance after shrinkage
• Conforms to irregular shapes for a snug fit
• Reduces chafing and protects from mechanical wear
• Maintains flexibility for routing and movement

What are the size and installation details I should know?

The sleeve starts at a 3/4" (19mm) inner diameter and shrinks approximately 50% after heating to about 3/8" (9.5mm). You receive a full 22-foot length so you can cut custom segments; trim stray threads at cut ends for a clean finish and measure components before cutting to avoid shortages.

• Flat width: approximately 1-1/8" before shrink
• Inner diameter before shrink: 3/4" (19mm)
• Inner diameter after shrink: about 3/8" (9.5mm)
• Total length supplied: 22 ft (cut to needed lengths)

Why use braided fabric tubing instead of solid heat-shrink or spiral wrap?

Braided fabric combines airflow and heat dissipation with the mechanical strength of a knitted sleeve, making it ideal where ventilation and abrasion protection are both needed. Compared with solid heat-shrink it remains flexible and resists water buildup, and compared with spiral wrap it provides seamless, continuous coverage.

• Open braided structure allows heat dissipation and prevents water pooling
• Stronger and more abrasion-resistant after shrinking than before
• Seamless coverage avoids snagging points common in wraps
• Flexible routing around bends and irregular shapes

How should I heat and finish the sleeve for best results?

Use a heat gun for even, controlled heating; move the gun in sweeping motions to avoid local overheating. After the sleeve has uniformly contracted, allow it to cool; cut edges cleanly and trim loose fibers to ensure a professional appearance and secure fit.

• Apply even heat—do not hold gun in one place
• Expect reduced length as the braid thickens during shrinkage
• Trim frayed ends with scissors for a tidy installation
• Test on a scrap piece if unsure of dwell time or temperature

Who is this for: Installers, hobbyists, and engineers who need a reliable way to protect and organize cables, hoses, and wire harnesses in environments where abrasion resistance, heat dissipation, and a neat appearance matter. This Sonoreboom sleeving is well suited for automotive and motorcycle wiring, marine rigging, home audio/video bundles, workshop equipment, and any project requiring a snug fit around irregular shapes.
