HST2441 is made from environmentally friendly, non-toxic PET fiber and PE heat-shrinkable yarn. It offers excellent noise reduction, flexibility, abrasion resistance, and heat shrinkability. This product can be easily installed on irregular hoses and reduces wear and noise levels in harsh environments, thereby extending equipment service life.
The Heat Shrink Textile Sleeving-HST2441 is a woven PET fiber and PE heat-shrinkable yarn sleeving engineered for automotive pipeline and hose protection. On heat activation, the sleeving contracts to conform tightly around irregular hose surfaces, providing consistent abrasion protection without adhesive or rigid fittings. HST2441 is rated for a working temperature range of -40°C to 125°C and is tested to the GB 8410-2006 automotive interior flame-retardant standard. The eco-friendly, non-toxic PET and PE construction keeps the product lightweight, which is relevant for weight-sensitive routing in new energy vehicle (NEV) powertrain assemblies.
Performance data for HST2441 is verified against standardized automotive test methods. All values listed are typical; project-specific test reports are available from your sales representative.
| Test Items | Test Method | Test Results |
|---|---|---|
| Temperature Resistance | 125°C, 240H thermal aging | Pass |
| Abrasion Resistance | TL52668-A scrub abrasion | ≥144,000 cycles |
| Flame Retardance | GB 8410-2006 | Pass |
The abrasion result of ≥144,000 cycles to TL52668-A is a defining specification. In field inspections of hose protection installations, wear damage concentrates almost always at the minimum bend radius of the routing path, not at entry fittings. A product rated to this abrasion threshold maintains its protective function precisely in the highest-stress zones of an automotive installation.
The Heat Shrink Textile Sleeving-HST2441 offers the following six performance characteristics:
This is the primary application for Heat Shrink Textile Sleeving-HST2441. Rubber hoses routed through engine bays that contact stamped-steel brackets under vehicle vibration are subject to progressive surface wear. HST2441 applies a tough, conforming abrasion barrier after heat activation, eliminating the bracket-contact wear mode without requiring hose rerouting or rigid protective tubes.
In NEV powertrain designs, copper and aluminum busbars require mechanical protection against abrasion and incidental metallic contact. The heat-shrink mechanism of Heat Shrink Textile Sleeving-HST2441 ensures intimate coverage of flat or irregular busbar cross-sections. The non-toxic PET construction avoids contamination concerns at precision electrical contact areas.
Standard tubular sleeving fits loosely on corrugated or non-uniform hose profiles. By heat-shrinking to the actual surface geometry, HST2441 delivers consistent protection coverage across diameter transitions and corrugated sections, which is the functional advantage that differentiates heat shrink textile sleeving from conventional braided expandable sleeving in complex installation geometries.
HST2441 provides abrasion and chemical resistance for harnesses routed near ignition components. The 125°C rated ceiling covers sustained engine-bay ambient temperatures under extended high-load operation, and the GB 8410-2006 flame retardance rating confirms regulatory compliance for these enclosures.
Buyers with prior experience specifying FEP heat shrink tubing should note that FEP heat shrink tubing is designed for dielectric insulation and chemical inertness in laboratory and medical assembly contexts, not for abrasion resistance under mechanical contact loads. Where the application requires sustained protection against metal bracket wear, a product with a verified abrasion rating such as the Heat Shrink Textile Sleeving-HST2441 is the appropriate choice.
For applications where a basic shrink wrap black covering is sufficient as a cosmetic or light physical shield, standard polyolefin wrap is a lower-cost option. However, the Heat Shrink Textile Sleeving-HST2441 is specifically engineered and tested for durability under repeated abrasive contact, which generic shrink wrap black products do not address.
HST2441 is available in 16 sizes from 6 mm to 100 mm unshrunk inner diameter, supplied on 50 m or 100 m spools.

The Heat Shrink Textile Sleeving-HST2441 is produced at a manufacturing facility certified to ISO 9001, IATF 16949, ISO 14001, ISO 45001, and military standard GJB9001C. For automotive supply chain qualification, IATF 16949 certification confirms the quality management framework required at Tier 1 and Tier 2 supply levels. Specification sheets, material data, and test report references are available to support customer qualification and supplier audit requirements.
To size the Heat Shrink Textile Sleeving-HST2441 correctly, identify the outside diameter of the hose or component at its maximum cross-section before installation. Select the smallest part number whose unshrinking I.D. value exceeds that OD, then confirm that the shrinking I.D. value is below the minimum OD of the protected component. This ensures a secure, non-slip fit after heat activation. Contact your sales representative with the hose diameter range, installation temperature, and chemical exposure details to confirm the correct part number.
