Non Shrink Tubing

ISG's non-shrink tubing range encompasses extruded PTFE, silicone, PVC, polyolefin and nylon sleeving products for wire insulation, harness protection and component covering in aerospace, defence and industrial environments. Unlike heat shrink variants, these products are installed over conductors and components prior to assembly or used as flexible conduit for ongoing accessibility.

PTFE sleeving provides exceptional chemical inertness and continuous service to +260°C, while silicone grades offer flexibility at extreme low temperatures down to -60°C. PVC variants are cost-effective solutions for general industrial applications. Products comply with BS EN 60684, DEF STAN and relevant AMS and ASTM specifications, with full dimensional traceability and test certificates available.

  • PTFE, silicone, PVC, polyolefin and nylon grades available
  • Continuous service temperatures from -60°C to +260°C
  • Compliant with BS EN 60684, AMS 3653, DEF STAN
  • Supplied in bulk reels or pre-cut lengths
  • Excellent chemical and solvent resistance (PTFE grade)
  • Flexible at cryogenic temperatures (silicone grade)
  • Dielectric strengths up to 20 kV/mm
  • Clear and coloured options for identification
