Heat shrink tubing in multiple colors with wiring harness connectors

Cable Protection

Heat Shrink Tubing & Cable Protection — coordinated from qualified Chinese suppliers.

Polyolefin and dual-wall adhesive-lined tubing, identification sleeves and high-temperature variants. We coordinate diameter, color, length, printing and packaging to your spec — and follow each shipment through QC and export documentation.

What we source

  • Polyolefin heat shrink tubing (2:1, 3:1, 4:1 ratios)
  • Dual-wall adhesive-lined tubing for sealing and strain relief
  • Identification and marking sleeves (printable)
  • High-temperature variants (PVDF, PTFE on request)
  • Multiple diameters and colors
  • Continuous reels or pre-cut lengths

Typical applications

  • Automotive wire harness termination
  • Electrical insulation
  • Cable protection and strain relief
  • Splice and connector sealing
  • Component identification and labeling
  • Outdoor and engine-bay wiring

Who buys these

  • Automotive OEMs and Tier suppliers
  • EV battery and electronics manufacturers
  • Industrial electronics OEMs
  • Electrical contractors and panel builders
  • Aftermarket harness shops
  • Telecom and infrastructure integrators

Customization options

  • Diameter, length and shrink ratio to drawing
  • Color matching and color-coded sets
  • Custom printing (text, logos, part numbers)
  • Adhesive class and adhesion level for dual-wall
  • Operating temperature range (typical −55°C to +135°C, higher on request)
  • Reel, pre-cut bag or kitted packaging

Quality & document support

What you get with the shipment.

We coordinate with qualified Chinese suppliers and factories holding ISO 9001, IATF 16949 or other relevant quality systems where applicable. Documents below can be requested as part of the project.

  • Material data sheets and TDS
  • RoHS / REACH declarations where applicable
  • Test reports — tensile, shrink ratio, dielectric strength
  • Supplier certificates (ISO 9001 / IATF 16949 where applicable)
  • Sample approval notes
  • Inspection reports per shipment

How RFQ works

From your spec to a structured quote — in days, not weeks.

  1. 01

    Send your spec

    BOM, drawing, sample photo or reference part number — via form or email.

  2. 02

    Supplier matching

    We shortlist qualified suppliers from our network and request comparable quotes.

  3. 03

    Sample & confirmation

    Optional sampling round; we manage sign-off against the agreed spec.

  4. 04

    Production & shipment

    Quality follow-up, document package, container loading and forwarder handoff.

FAQ

Common questions before sending an RFQ.

Do you make heat shrink tubing yourselves?

No. We are a sourcing and supply chain management company. We coordinate qualified Chinese factories to manufacture against your spec, and we manage QC and documentation through to shipment.

Can you match brand-name tubing such as Raychem or Sumitomo grades?

We support specification matching and alternative sourcing on dimensions, ratio, color, temperature class and adhesive properties. We do not represent ourselves as authorized distributors of any specific brand; we coordinate Chinese suppliers whose products are technically matched to the reference.

What is a realistic MOQ?

Standard polyolefin tubing in common diameters often has low MOQs (tens of thousands of meters or fewer). Dual-wall, custom colors and custom printing increase MOQ. Send your spec and we will return a MOQ breakdown alongside the quote.

Can you provide marked or printed tubing?

Yes — text, part numbers and logos can be printed on identification sleeves and on heat shrink tubing itself depending on the print method. Share the artwork or part-number scheme and we'll confirm feasibility.

What about temperature class and certification?

We can source tubing in standard automotive temperature classes. Where the project requires specific approvals (UL, AAR, OEM-specific), we coordinate with suppliers who hold them and include relevant documents in the shipment package.

How fast can you turn around a sample?

Stock samples often ship within a few business days; custom-printed or custom-color samples take longer. We confirm the realistic sample timeline before you commit to anything.
