2:1 Heat Shrink Tubing
Professional Grade Flexible Flame Retardant Polyolefin
Insulate, Seal and Protect Hoses, Braided Sleeving and Cable Splices
|
What's special about this heat shrink tubing?
This high performance, multi purpose polyolefin based, heat shrinkable tubing meets/exceeds all specifications for electrical, chemical and physical properties. It is designed for a wide range of applications, including military and commercial, and for the consumer/OEM market requiring Underwriters Laboratories and/or Canadian Standards approval. It is used extensively for cable and wire harnessing, strain relief, insulation, color-coding, identification and protection |
- Available in 17 sizes to securely cover a variety of applications, such as terminating the ends of braided sleeving, or neatly bundling a group of cables together
- Chose from 12 colors for color coding wiring, or to match the cable jacket when protecting asplice
- Meets or exceeds all Military specifications for a reliable quality installation
- LG heat shrinkable and non-shrinkable tubing products do not contain the compound Di (2-ethylhexyl) phthalate commonly referred to as DEHP
- In addition, LG heat shrinkable and non-shrinkable tubing products do not contain PFOS (perfluoroctane sulfonate), PFOA (perfluorocanoic acid) or Tinuvin 320
Due to the nature of heat shrink, it does shrink length wise as well as the diameter 2:1 heat shrink will shrink 7% or less in the axial direction during the shrink process
UV Reactive or Glow in the Dark Heat Shrink
We now stock PVC heat shrink, in bright highly UV reactive neon colors. It is available in a 2:1 shrink ratio, and three sizes (1/4", 3/8", 1/2"). Colors currently available are Luminous Pink, Neon Pink, Neon Yellow, Neon Green, Luminous Green, and Gold. For more information and pricing, click here.

Adhesive Lined Tubing
Our 2:1 heat shrink tubing is also available with a “dual-wall” construction. During application, the inner layer melts and flows, creating an adhesion layer to ensure a snug fit to your harness and/or connector. It is also recommended for applications that require a water-tight seal to protect wire, cable and connector components.
2:1 Dual Wall requires a 100 FT Minimum Purchase. Please Call 1-866-222-0030
