Self-Winding Textile Sleeve
Self-Winding Textile Sleeve is built from Polyester braid. It is a non-shrink sleeve you slip over the part; it stays in place by fit and friction, with no heating step. On the shelf it is held to working range -40℃~+190℃. Buyers spec it for NEV wire harness and fuel lines — the typical call is a sized part that stays put through vibration, thermal cycling and field handling. Below is the spec table, the size matrix we keep in stock, and the selection notes our engineering team uses when a purchaser sends a cable or component drawing.

What it is and how it recovers
Self-Winding Textile Sleeve is a braided or wrapped sleeve that goes on by sliding. It holds by friction and the spring of the weave, so there is no recovery step and no heat. Because the body is Polyester braid, it keeps its insulation and protection through handling and thermal cycling. For procurement this matters: the part you receive is reusable on the bench, but once installed it stays put for the life of the assembly.
Where Self-Winding Textile Sleeve is used
Primary applications: NEV wire harness and fuel lines.
How to select the right size
Specifying Self-Winding Textile Sleeve is mostly about matching three numbers to the part you are covering:
- Recovered vs. supplied diameter. Pick the supplied (expanded) ID at least Spiral wrap× the object's largest diameter so the sleeve slides on, then confirm the recovered ID grips it. When in doubt, size up one step rather than forcing a tight fit.
- Temperature class. The continuous range is -40℃~+190℃. If the assembly sees brief excursions beyond that, tell us — we will flag a high-temp grade instead of letting the wall soften in service.
- Wall and adhesive. Thin wall for tight harness bundles; medium/thick wall or adhesive-lined (dual-wall) where you need environmental sealing or abrasion resistance. We keep both in stock.
Frequently asked questions
What shrink ratio should I choose for Self-Winding Textile Sleeve?
If the connector or lug is only slightly larger than the wire, a 2:1 ratio is enough. When one sleeve must cover both a bare conductor and a bulky barrel, ask for 3:1 or 4:1 (we stock Spiral wrap). The rule is: supplied ID ≥ ratio × largest object OD.
Can Self-Winding Textile Sleeve be used outdoors / buried?
Single-wall polyolefin is fine for indoor harness protection. For outdoor, buried or wet locations specify the adhesive-lined (dual-wall) version — the melt adhesive seals out moisture and resists tracking. Tell us the environment and we point you to the right wall type.
What is the temperature limit of Self-Winding Textile Sleeve?
Continuous operating range is -40℃~+190℃. Brief excursions above that are possible with the right grade; for sustained high heat we recommend the silicone-fiberglass or fluoropolymer family instead.
