Engineering guide

How to choose electrical insulation sleeving.

Turn seven application inputs into a clear material and size request.

A practical RFQ starts with the operating envelope.

Record continuous and peak temperature, working voltage, required inner diameter and tolerance, movement or abrasion, chemical exposure, installation method and required standards. Then request a sample built to the exact configuration.

Specification checklist

  • Operating and peak temperature
  • Working voltage and dielectric requirement
  • Inner diameter, tolerance and wall construction
  • Movement, abrasion and chemical exposure
  • Required standards, color, length and quantity
Final values, certification scope, MOQ and lead time must be confirmed against the selected FRT product code.
