LHT Highly Flexible, Heavy Duty Conduit-1

GD BESSES LHT Highly Flexible, Heavy Duty Conduit The main characteristic of this medium to heavy walled polyamide 12 conduit / tubing is the high fatigue strength while undergoing reverse bending stress. LHT is ideal for continuous dynamic use at very low temperatures. With its smoke, flame and toxicity certifications and excellent UV and weathering resistance, LHT is particularly suitable for outside dynamic use on people movers, railway vehicles (roof, bogie & undername), public transit, robotic applications and solar tracking systems & arrays. • High-grade, specially formulated polyamide 12 • Halogens and cadmium free • Excellent weather and UV resistance • Enhanced flexibility and fatigue strength • Excellent mechanical strength (compression/impact) also at low • Self-extinguishing with very low smoke development Specifications are subject to change without notice
