Conductive Heat Shrink Wire Connectors

Splices Together Coaxial Cables & Provides a Connection


What's special about these Wire Connectors?

  • When used to join coaxial or electrical cables, the inner coating provides a connection between the two splices
  • Offers shielding from EMI, RFI, and ESD to protect the cable joints
  • Constructed of MIL Standard R-46846 polyolefin tubing and a highly conductive polymer thick film
  • Requires only a Heat Gun or Oven to shrink and create the connection
  • Click for More Features

EMC shrinkMate heat shrink wire connectors are composed of MIL Standard R-46846 polyolefin tubing and a highly conductive Polymer Thick Film silver inner diameter coating. The coating shrinks with a heat gun, oven, or any other conventional heat source. When the tubing is set, the inner conductive layer provides an electrical connection between the outside surface of the objects that are joined by the tubing.

Coaxial cable butt joints and cable to shielded connector housing joints can be made fast and easy and without the use of solder.

Heat Shrink Electrical Connectors
Electrical connections are possible with EMC shrinkMate heat shrink wire connectors between components of various sizes and shapes, and between solderable and nonsolderable surfaces, such as stamped metal, plated finishes, and shielding paints.
Heat Shrink Butt Connectors
EMC shrinkMate heat shrink electrical connectors are entirely coated on their inner surface providing not only electrical continuity, but EMI, RFI, and ESD shielding around the joints being connected.

  • 2:1 shrink ratio
  • MIL Standard R-46846

The resistance of a shrunken tube is approximately 1 per inch. The resistance of any splice is determined by the gap between two objects being spliced. A 0.1 inch gap will have 0.1 per inch resistance.

Passes the Aerospace Industry General Specification Vacuum Stability Requirements of Polymeric Material for Spacecraft Application for Mass Loss and Collected Volatile Condensable Materials per ASTM E-595, NASA Sp-R-002A and ESA PSS-01-702.

Shielding needs depend on the application, and will be dependent on the internal design but typical “High Frequency” shielding needs are:

Commercial 30-60 dB (30-1000x)
Military 60-90 dB (1000 - 30,000x)
Special 90-120 dB (30,000 - 1,000,000x)

Practical upper limit for enclosures & rooms is 120 dB.

Questions & Answers


Heat shrink size - Is the heat shrink nominal diameter before or after shrinking?

Asked by Barry W. on 10.08 PM Thursday, 21 January, 2016

  • - Our conductive heat shrink is measured by diameter. The Nominal ID listed on our site is the expanded (pre-shrunk) diameter of the tube. In the case of this tubing, you may expect that it will shrink to half the diameter of that starting size.
