ROCKDIG Heat Shrinkable Braided Sleeving (20 ft, 1/2″)
The ROCKDIG braided sleeving uses PET fiber and PE filaments, delivering a 2:1 shrink ratio that reduces to half its original diameter. It operates from -55° C to +135° C, with a maximum continuous use temperature of 135° C. The sleeving offers outstanding noise reduction, flexibility, heat resistance, and moisture and abrasion protection. It is designed for quick, even shrinking with a heat gun, providing a snug fit over wires and connectors for reliable cable protection.
Alex Tech 25ft – 1/2 inch Cord Protector
This split cord protector is 1/2 inch in diameter and 25 feet long. It features a split design for easy loading of wires, then closes on itself to form a neat wrap. Operating temperature ranges from -103° F to 257° F, with a melt point around 446° F. It is suitable for automotive, Hifi, HDMI, and other cable applications, helping keep cables insulated and protected from pets and abrasion.
BuyUneed 2:1 Shrinkable Braided Sleeving (1/2″ ID, 16ft)
BuyUneed’s sleeving is a 2:1 heat shrink braided sleeve made from polyolefin and polyester yarns. It shrinks to 1/2 of its original diameter and provides abrasion protection while retaining flexibility. The sleeve handles high temperatures, offering reliable flame and high-temperature resistance across a range from -40°F to 257°F. It is designed for cord management and cable protection in demanding environments.
100ft 1/8 inch PET Expandable Braided Sleeving
Alex Tech’s 100 ft expandable sleeving features a 1/8 inch diameter, expandable by 50%. Made from PET material, it withstands temperatures from -103° F to 257° F and has a melt point of 446° F. It is UL, ROHS, and REACH compliant and suitable for automotive, audio, HDMI, and general wiring applications. The expandable design helps accommodate irregular shapes and facilitates maintaining a clean harness appearance.
MTJSWXSY Automotive Wire Loom, 20 ft – 1/4 inch
MTJSWXSY’s high-temperature braided wire loom offers a split-sleeve, self-wrapping design for easy installation and enhanced wire security. It tolerates heat up to 302°F and is made from heat-retardant PET polyethylene material. The tightly woven, abrasion-resistant sleeve provides protection for harnesses with an overlap design that helps prevent braid separation while remaining flexible enough for complex routing and drainage in automotive environments.
Buying Guide
- Temperature rating: Match the sleeving’s operating temperature with your environment. High-temp applications may require sleeves that tolerate 250–300°F or more.
- Sleeving type: Decide between heat-shrink braided sleeves (tightly cinch after heating) and split/loom sleeves (split for easy loading and re-sizing).
- Diameter and shrink ratio: Determine the required ID before and after shrinking. A 2:1 shrink ratio is common, halving the diameter when heated.
- Material and certification: PET and polyolefin-based sleeving with UL/ROHS/REACH may offer better safety and compliance for sensitive electronics.
- Installation method: Heat gun compatibility for shrink sleeves; ease of loading for split loom types is a practical factor in busy projects.
- Application fit: Consider automotive, home theater, or industrial environments to select abrasion resistance, moisture protection, and flexibility levels.
- Durability vs. flexibility: Higher braid density improves protection but may reduce flexibility; balance for your routing needs.
