Automotive Wire Harness Protection Sleeving

Automotive wire harness wrapped in PET braided sleeving inside an EV battery pack, showing abrasion and fluid resistance

Automotive and EV harnesses face abrasion, heat, fluids and constant vibration. The sleeving you choose decides service life. Here are the three families buyers weigh.

PET braided mesh

PET braided sleeving is the default for bundles: expandable, breathable and abrasion resistant, with a clean look on the line. For half-rolled or pre-open styles see PET half-rolling sleeve.

Textile and self-winding

Self-winding textile sleeving wraps without tools and holds its shape, good for service loops and routed sections. Anti-breakout boots cap the harness end and stop the sleeve fraying at the connector.

Heat shrink where sealing is needed

At connectors and splices, adhesive-lined dual-wall seals against moisture and fluids. For EV battery-pack looms, pair braid with sealed boots at every breakout.

What to send

Bundle OD, temperature class, abrasion level and whether the route is open or enclosed. See matched parts under automotive & EV solutions.

Quick selection checklist

  1. Measure the bundle OD at its widest point and at every breakout.
  2. Set the temperature class from the hottest point along the route.
  3. Rate the abrasion duty: open route, enclosed duct, sharp edges, or constant vibration.
  4. Pick the family. PET braid for general bundles, self-winding textile for tool-free wrap on fixed sections.
  5. Add adhesive-lined dual-wall at connectors and splices, and a sealed boot at every breakout.
  6. Send bundle OD, temperature class, abrasion level and route type for a sized recommendation.

Frequently asked questions

PET braid or textile for a routed loom?

PET braid for general bundles; self-winding textile where you need tool-free wrap on a fixed section.

How do I stop the sleeve fraying at the connector?

Cap it with an anti-breakout boot or a sealed heat shrink end.

Is this suitable for EV battery packs?

Yes, use braid plus adhesive-lined dual-wall at every breakout for moisture sealing.
