Custom Electrical Wire Identification Markers: Heat Shrink, Hot Stamp & Thermal Transfer

Electro Insulation Corporation manufactures and supplies high-performance electrical wire identification markers for aerospace, military, industrial, and commercial applications. Our heat shrink wire markers and non-heat shrinkable wire identification markers are available in both hot stamp and thermal transfer formats, allowing you to permanently identify wiring systems with custom logos, part numbers, date codes, serial numbers, and sequential identifiers. All wire markers meet UL, CSA, and military specifications and are fully RoHS compliant.

Heat Shrinkable Wire Identification Markers

Our heat shrink wire markers provide permanent, tamper-resistant identification for electrical wires and cables across the harshest environments. Available in virtually all tubing types, these heat shrinkable wire identification markers are engineered to shrink securely around the wire, locking your markings in place even under exposure to fluids, vibration, and extreme temperatures.

Key Features:

  • Custom logos, part numbers, date codes, and serial numbers available
  • Available on virtually all tubing types and sizes
  • Computer-printable wire markers with complete printing systems available
  • Permanent identification sleeves that will not loosen, peel, or migrate
  • Lightweight design engineered for aerospace applications
  • Meets UL, CSA, and military specifications (hot stamp only)
  • RoHS compliant
  • Available in 2:1 and 3:1 shrink ratios
  • Standard colors: white and yellow; additional colors available upon request

How Heat Shrink Wire Markers Work:

Heat shrink wire markers are slipped over the open end of a wire before termination, then positioned and heat-shrunk in place to create a permanently bonded identification sleeve. Once applied, the marker resists abrasion, common fluids, lubricants, and solvents, making them the preferred solution for demanding electrical and aerospace wiring applications.


Non-Heat Shrinkable Wire Markers

For applications requiring identification after termination or where a simpler identification method is preferred, Electro Insulation offers a complete line of non-heat shrinkable wire markers. These are available in pre-printed cards, books, and tie-on cable marker tags designed for large cables, cable bundles, conduit, and more.

Key Features:

  • Available in pre-printed cards, books, and tie-on cable marker tags
  • Wide operating temperature range: -55°C to +225°C
  • Standard colors: white and yellow; additional colors available upon request
  • Meets UL, CSA, and military specifications
  • RoHS compliant
  • Ideal for use on large cables, conduit, and cable bundles

Tie-on cable marker tags are applied using cable ties, allowing identification of large cables and bundles either pre- or post-termination and providing flexibility for both field and panel applications.
