Alex Tech 1" PET Expandable Braided Sleeving

Alex Tech's 100ft, 1-inch PET expandable braided sleeving in BlackRed is a flexible, heat-resistant cable protector that expands to fit bundles and keeps wiring organized and safe.

Built from PET (polyethylene terephthalate), this 100-foot spool of braided sleeving combines abrasion resistance, temperature tolerance, and a clean woven finish to manage and protect wiring in automotive, audio, home theater, computer builds, and general industrial applications. The sleeve expands by up to 50% in diameter to accommodate connectors and grouped cables while maintaining a snug, low-profile wrap.

How does this braided sleeve simplify cable organization?

The flexible braid lets you gather multiple wires into one neat bundle, reducing clutter and improving airflow. Its expandability makes it easy to feed cables through the sleeve without disconnecting components.

• 1-inch base diameter expands about 50% to fit mixed cable sizes.
• 100-foot length provides long continuous runs or many shorter segments.
• BlackRed woven finish visually separates cable groups for quick ID.
• Quick installation — push cables in or wrap around existing bundles.

Is this sleeving durable and safe for high-temperature environments?

Yes — the PET material withstands a wide temperature range and resists melting up to its specified melt point. It’s flame-resistant and certified to several industry safety standards for added reliability.

• Operating temperature range: -103°F to 257°F for cold and heat tolerance.
• Melt temperature: 446°F, reducing risk of deformation under heat.
• Certifications: UL, RoHS, REACH, and halogen-free for compliance.
• Braided construction provides abrasion and wear resistance over time.

How should I cut and finish the ends to prevent fraying?

To keep the braid from unraveling, cut with a hot knife that seals the edge as it slices. If a hot knife isn’t available, use another heat source to carefully melt the cut ends and close the weave.

• Recommended: hot knife cut to seal the braid and prevent fray.
• Alternative: carefully singe edges with a lighter or soldering iron.
• Trim excess slowly and test a small scrap first to avoid damage.
• Use heat-shrink tubing for a clean transition at connectors if desired.

What applications is this sleeving best suited for?

The BlackRed 1" braided sleeve is ideal where visible cable runs require both protection and a finished look. It works well in automotive installs, home theater systems, HiFi audio setups, computer cable management, and light industrial wiring.

• Automotive wiring looms, speaker and amplifier cabling.
• Home theater and HDMI cable organization behind racks.
• PC builds and server cable bundles for improved airflow.
• Industrial or commercial wiring where abrasion resistance is needed.

Who is this for: Installers, hobbyists, and professionals who need a long, flexible, and durable braided sleeve to protect and organize cables will value this 100-foot spool. Choose Alex Tech’s BlackRed PET braided sleeving if you want a compliant, heat-tolerant wrap that expands for easy installation and gives wiring a professional, color-contrasted finish.
