Black expandable braided sleeving on spool, 3/8 inch diameter by 25 feet

Bolton Technical

Bolton Technical 2 in 1 accessory 3/8 inch 25ft

SKU CH-4C0V-AJZQP

Heat-shrink braided sleeving protects cables with 2:1 shrink ratio, 150000-cycle abrasion resistance and -30F to 297F temperature range

  • Withstands 150,000 abrasion cycles for lasting protection
  • Shrinks to half its diameter with heat for a secure fit
  • Operates continuously from -30F to 297F for insulation
  • Cuts easily with scissors to suit irregular shapes
  • 25ft length covers multiple cable runs in one sleeve

Cable Protection Sleeve

This 25 ft heat-shrink braided sleeve combines polyester fiber and polyethylene in a tightly woven structure rated for 150000 abrasion cycles. It suits installers who need a single length to cover office, home or automotive wire harnesses and irregular shapes. The material stays stiff after shrinking for lasting mechanical protection.

2:1 Shrink Ratio and Thermal Range

A hot air gun shrinks the tubing to half its original diameter, locking the harness in place and preventing slippage. Continuous operation is rated from -30F to 297F, providing sealing and insulation across that span without additional cooling or derating.

Sustained High-Temperature Use

Under prolonged exposure the sleeve maintains its dimensions and abrasion resistance up to the 297F limit, so harnesses in engine bays or near heating equipment remain protected. It cuts cleanly with scissors for quick termination during long runs.

Questions about this item

How do I install the 3/8 inch sleeving and what step is often missed?

Cut the 25ft sleeve to length, slide it over the cable, then apply a hot air gun evenly until it shrinks to half its diameter; the step often missed is heating all sides uniformly so the 2:1 ratio closes without gaps.

What maintenance or replacement will the braided sleeve need later?

The polyester and polyethylene construction resists abrasion up to 150000 cycles and stays stiff after shrinking, so no routine maintenance is required; replace only if the sheath is physically cut or melted beyond the 297F continuous rating.

What limit appears first during sustained high-temperature use?

Continuous operation is rated to 297F; exceeding this temperature will degrade the material before the abrasion limit of 150000 cycles is reached.
