Sleeving and conduit for wire harness manufacturers
Harness makers combine several protection products on one assembly: braided sleeve on the trunk, wrap on the branches, conduit near hot or moving parts. We make and stock that whole range, so one supplier can cover a complete harness drawing.
What goes wrong with cables in wire harness
Chafing at clamps and edges
Vibration rubs cables against brackets and sheet metal until the insulation wears through.
Branches and breakouts
Sleeve has to pass over connectors and still fit the bundle tightly after the breakout.
Heat near engines and exhausts
Some branches run close to heat sources and need conduit or fibreglass instead of PET.
What we supply for wire harness
PET expandable sleeve
Expandable braid that slides over connectors and closes down on the bundle. FR and non-FR grades, 3 to 70 mm.
See sizes and datasheetSelf-closing wrap
For branches that are already terminated. PET, -50 to +125 °C, FMVSS 302 reference.
See sizes and datasheetABRO braided tube
Dense braided tube where abrasion is the main risk.
See sizes and datasheetPA-6 FR flexible conduit
UL 94 V-0, IP68, halogen-free conduit for routing near heat and moving parts.
See sizes and datasheetNylon spiral wrap
Spiral wrap for quick bundling and for branches that need to break out anywhere along the run.

Frequently asked
What sleeve is best for automotive wire harness?
PET expandable sleeve is the most common for trunks. Self-closing wrap suits terminated branches, and FR conduit is used near heat. Share your drawing and we will mark up the options.
Can you match a customer's colour or FR specification?
PET and nylon braid can be made in colours to specification, with FR grades. Lead time for custom constructions is 1 to 2 months.
Do you supply harness makers outside India?
Yes. We export to markets including the UAE, Bangladesh, Nigeria, Malaysia, Australia, Germany and Poland. Ex-factory terms are preferred.
