Construction
The Non-UL EXTREME TEMPERATURE Liquidtight, Flexible Steel Conduit core shall be formed into a very flexible interlocked steel conduit from a zinc coated galvanized low carbon steel strip having a uniform width and thickness. The convolutions of the interlock shall be filed with a fibrous material designed to promote flexibility.
Jacket – TPR
A rugged moisture, oil and ozone resistant thermoplastic elastomer jacket shall be extruded directly over the interlocked very flexible steel core. The jacket is halogen free, has a UL 94HB Flammability Rating and has a –60°C (–76°F) Low Temperature Brittle Point when tested in accordance with ASTM® D–746. 720-Hour Xenon-Arc sunlight/weather resistance – ASTM D2565 and ASTM G155.
Temperature Rating
- 150°C/302°F Dry – Continuous use
- 70°C Oily and wet
- –60°C/–76°F Low temperature brittle point
