Innovation in hose protection is brought about by our abrasion resistant braided sleeve, featuring heat-shrink braided sleeving technology. Custom Hoses’ page showcases the product that offers dual-layer protection where a polyester braid provides abrasion resistance, and 2:1 polyolefin heat shrink offers snugness. It tackles issues such as abrasion, vibration, and chemical exposure on wires and hoses seamlessly. From safeguarding high-performance fuel lines to industrial air hoses, this solution offers elegance alongside durability.

Our braided heat shrink variant offers uniform, solid adhesion when heated, ensuring no slippage or movement and resulting in a streamlined finish. Serving customers by the meter means bespoke lengths for tailored designs are possible, including intricate spur gear layouts. The flame retardant features certified standards ensure the sleeve maintains top-tier safety even in high-temperature zones.

Most importantly, this sleeve withstands hydraulic fluids, oils, coolant, and fuel, making it ideal for applications that require resilience. Overall performance of heat shrink braided sleeving claims unmatched strength from custom hoses against abrasions while still providing thermal protection and ease of installation tailored for demanding users.

What Is Heat Shrink Braided Sleeving?

Heat shrink braided sleeving is a protective composite system that joins the pliability of braided polyester and the sealing effectiveness of heat shrink tubing. Essentially, braided polyester provides mechanical protection, and polyolefin heat shrink both provides bonding and shrinks to 50% of its diameter. The consistent 2:1 ratio ensures that no air gaps exist, providing resilience while maintaining an ideal fit for the braid.

Construction involves wrapping polyester multifilament around a core made from polyolefin, resulting in a sleeve that is both flexible and expandable, which can be shrunk upon heating. This construction enables covering irregular shapes, such as hose bends or fittings, followed by a snug fit upon applying heat with a gun. The combination provides unparalleled abrasion resistance while offering flexibility.

Thermal performance remains exceptional—the start and endpoint of shrinkage sit at ~110 °C and 150–185 °C, respectively, with reliable operation between –40 °C and +125 °C (some sources claim up to +140 or even +150 °C). The flame retardant property (VW 1 rating) alongside RoHS compliance places this sleeve far above many target regulatory standards, making it suitable for demanding client applications.

Important Technical Details

Considerations of abrasion resistant braided sleeve specifications are important for sleeving selection considering system requirements:

  • Shrink Ratio: 2:1—maximum reduction to half of the original diameter
  • Temperature range: –40 °C to +125 °C (select sellers may state up to +140 or +150 °C).
  • Shrink Activation Temperature: Starts around 110 °C, fully shrinks between 150-185 °C
  • Double wall thickness post-shrinkage: Approximately one millimeter adds significant mechanical strength
  • Flammability Rating: VW 1 flame retardant classification
  • Chemical Resilience: Hydraulic fluids, fuels, oils, coolant/antifreeze, and even battery acid have no corrosive impact.
  • Material Composition: Polyester braid covering a modified polyolefin monofilament

However, these sleeves can be ‘slipped on’ and then heated, resulting in a rugged, industrial cut-resistant sleeve that withstands harsh conditions, such as fuel and saltwater, while enduring extreme heat, making it ideal for automotive applications.

Primary Advantages of Our Sleeve

This abrasion hose sleeving shines when it comes to practical performance:

Toughness & Wear Resistance 

The exterior braided structure excels at resisting cuts, chafing, and vibration—essential when hoses rub against one another or brackets.

Secure Seal & Bundle Integrity 

Once heat-shrunk via heat-shrink braided sleeving, the sleeve forms an impenetrable grip—no shifting or exposure of underlying hoses.

Dual Functional Benefits 

Combines the abrasion defense of braided sleeving with the seal and fit of heat-shrink tubing—one product, two types of protection.

Thermal & Flame Safety 

Maintains performance up to 125 °C, self-extinguishing with VW 1 flame rating—ideal for systems with overheating potential.

Noise & Vibration Dampening 

Benefits in vehicles and machinery include a snug apparatus reducing external noise and rattling.

Chemical & Fluid Resistance 

Unphased by fuel and brake fluids, as well as antifreeze and engine oil, make them perfect for use around engines or hydraulic systems.

Flexible, Reliable Installation 

Joins are easy to slide over bends, shrink cleanly, and are removable if replacement is needed.

Ideal Applications & Use Cases

Designed for resilience, neatness, and safety where high demand is needed, this abrasion-resistant braided sleeve finds use in:

  1. Automotive & Motorsport

Safeguarding oil and fuel lines, turbo hoses, as well as coolant circuits where heat, friction, and movement are high.

  1. Industrial & Machinery

Protect gas conduits and hydraulics in pneumatics manufacturing on heavy equipment, particularly around clamps or where hoses come into contact with metal surfaces.

  1. Electrical & Wire Harness Management

Better than plain looms: protects wires from rodents’ chews or abrasions while neatly bundling them.

Installation Guide: Getting It Right

Precise application of the abrasion-resistant braided heat shrink ensures optimal performance with only a few straightforward steps:

  1. Measure and Cut

Select a sleeve that will shrink onto the hose, allowing it to glide on easily before reducing in size while providing ~10% extra post-hose length after the hose is trimmed.

  1. Slide Over And Position

Position the sleeve so that all the areas needing protection are adequately covered.

  1. Apply heat evenly

For best results, use a heat gun set between 120-150 degrees Celsius and keep it roughly 50 mm away, moving slowly to allow for uniform shrinking.

  1. Check complete shrinkage

Ensure the sleeve is snug and there are no gaps. If necessary, trim the ends for a cleaner look.

  1. Remove or replace

If needed later, slit the braided sleeve longitudinally and carefully peel it off to remove it in braids, as observed above.

These steps will help ensure that your braided heat shrink performs optimally, providing reliable and durable protection.

Informative Actions on The Maintenance & Safety Issues

To maximize the lifespan of the abrasion-resistant braided sleeve, consider the following:

  • Direct flames should be avoided at all costs; hot air, being the less harmful alternative, should be kept below the lowest settings since direct flames might be too blistering.
  • Careful inspection is a must; Look for observable lacerations, scrapes, or dirt residue.
  • Maintain rigorously but give care not to scrub harshly; Detergent will benefit, while solvents harm sleeves’ ability to serve correctly.
  • So, selected edges will ensure newly placed edges won’t undo themselves.
  • Sleeves need to be pasted strongly on the face for best results. Attempting to preheat prevents optimal results.

Final Takeaways

Manufactured from special fireproof fabrics, this heat shrink braided sleeving with a 2:1 shrink ratio, is sold per meter and offers unparalleled protection for hoses and wiring. For industrial applications or protective sleeving in automotive, marine, or DIY projects, the braid’s ruggedness, coupled with its ease of handling, makes it an ideal abrasion hose sleeving solution. Custom Hoses truly deliver performance and peace of mind—buy once, protect forever.
