Heat-Shrink & Cable Protection
Select heat-shrink tubing and protective sleeving by material, recovery ratio, temperature, sealing, electrical and installation requirements.
Product families
Polyolefin, adhesive-lined, PTFE/FEP/PFA, silicone, PET/PVC, fiberglass insulation sleeving, fire sleeve, busbar insulation and cable accessories.
Selection inputs
- Largest object before recovery and smallest sealed dimension
- Continuous and installation temperature
- Chemical, UV, moisture and abrasion exposure
- Electrical or mechanical protection objective
- Heating method and installation access
Specialist resources
See HeatShrinkTubes.net for current commercial products. Confirm recovery dimensions, test methods and approvals before use.
Heat-shrink and cable protection resources
This topic center supports engineers and buyers who need to convert an application into a heat-shrink tubing specification. Start with the substrate and protection objective, then define material compatibility, operating and installation temperatures, supplied and recovered dimensions, shrink ratio, recovered wall, longitudinal change and the heating process. Confirm performance on the actual assembly rather than relying on nominal material labels.
Recommended guides
- Heat-shrink tubing selection: material, shrink ratio and installation
- FEP heat-shrink sizing: recovered ID, wall and longitudinal change
- PET/Mylar heat-shrink for cells and electronics
- PTFE vs FEP heat shrink for catheter reflow
- Electrical insulation tube material selection checklist
- Medical catheter liner material comparison
- Medical FEP tubing: clarity, cleanliness and packaging
- 2:1 vs 3:1 vs 4:1 heat-shrink sizing rules
- Recovered wall thickness: insulation vs stiffness
- Heat gun vs oven vs reflow validation
A complete RFQ identifies the substrate, application environment, required coverage, supplied ID, recovered ID, maximum recovered wall, cut length, color, installation method, applicable tests, packaging and demand volume.
Selection checklist
- Recovery fit: supplied ID against the largest object, and recovered ID against the smallest sealed dimension.
- Shrink ratio: 2:1, 3:1 or 4:1 chosen from both diameters, not from the ratio alone.
- Temperature: continuous and installation temperature at the part, not the tool setpoint.
- Environment: chemical, UV, moisture and abrasion exposure of the installed location.
- Sealing: whether adhesive-lined recovery is needed for environmental sealing.
- Installation: heating method and access available on the actual assembly.
- Verification: recovered dimensions, longitudinal change and recovery test on the part.
