Introduction
  Description


EPDM Rubber Cold Shrink Tubing is a factory-expandedand placed on a removable plastic core. Simply prepare the connection, positionthe tube and unwind the pre-scored core. The natural tendency of the rubbersleeve to return to its original diameter provides constant radial pressure,forming a reliable, water resistant seal .All without heat, special tools or atime-consuming installation procedure. And, it’s easily removed when systemmaintenance is required.  


Unique Advantages

  • Excellent weather resistance, ultraviolet aging resistance and higher embrittlement resistance than heat shrink tubing
  • More resistant to slab and prick, abrasion, acid and alkali than silicone cold shrink tubing
  • Simultaneously expands and shrinks with workpieces without clearances, seals tight in harsh   environment
  • Stably sealing the work pieces in windy environment
  • Well suited for cable less than 1KV
  • Seals tight, retains its resiliency and pressure even after prolonged years of ageing and exposure.
  • Simple, safe installation requires no tools or special training. No torches or heat work required.
  • Diameter shrinkage:≥50%
  • Standard color:black


Applications
Volsun Cold Shrink Tubing series can be used for sealing of coax cables with Type N or 7/16 DIN connectors.
Installation features make it the preferred coax connection seal;
Simple installation requires only the installer’s hands.
Excellent weathering properties.
Excellent abrasion resistance
