SKU CH-176K-5T1SG

Heat-shrink conduit protects wires with a 2:1 ratio, VW-1 flame rating and oil-resistant polyolefin on a 50 ft mini reel

  • Thin 2:1 shrink ratio insulates and protects wires
  • UL 224 VW-1 rating meets high flame-protection requirements
  • Flexible cross-linked polyolefin resists common oils and chemicals
  • Continuous operating range from -67 °F to +275 °F
  • 50 ft mini reel suits small-to-medium volume jobs

Heat-shrink conduit for wire protection

HellermannTyton 309-60294 is a thin-wall polyolefin tubing that shrinks 2:1 from 4.8 mm to 2.4 mm. The black conduit comes on a 50 ft mini reel and carries UL 224 VW-1 flammability recognition. It suits technicians insulating and marking cables in automotive or industrial electrical work.

Suits installers needing flame-rated sleeve

The tubing resists common oils, chemicals and fluids while operating from -55 °C to +135 °C. It is not halogen-free, so buyers who require low-smoke zero-halogen material should look at alternative products. The thin 0.019 in wall also means it will not provide heavy mechanical armouring for harsh-abrasion zones.

Stable dimensions under continuous heat

Cross-linked polyolefin maintains its recovered 2.4 mm diameter after prolonged exposure at the upper 135 °C rating without cold-flow deformation. The VW-1 rating confirms the material self-extinguishes during sustained flame contact rather than only in brief bursts. Colour and wall thickness remain consistent throughout the full 50 ft length.

Questions about this item

What wire size fits the 4.8 mm expanded diameter?

The tubing expands to 4.8 mm and shrinks to 2.4 mm, covering wires up to roughly 4.8 mm in diameter.

Can it protect cables that already have older insulation?

Yes, the thin-wall polyolefin slides over existing insulation and shrinks 2:1 for abrasion and fluid resistance.

How do I confirm the shrink has activated correctly?

Heat until the tubing conforms tightly to the wire; the 2:1 ratio means the final diameter will be about 2.4 mm.
