Flexible Ceramic Composite Hose Ultra Wear Resistant Bend Radius 5x Diameter Non Stick Surface
Explosion Proof Flexible Ceramic Duct
ATEX/IECEx-certified for Zone 21/22, this hose combines conductive ceramic lining (surface resistivity <10⁶ Ω) with a static-dissipating EPDM cover. The helical steel wire support ensures crush resistance while maintaining bend radii down to 4x diameter. Safely handles combustible dusts (STM-D12 tested) and flammable vapors. Pressure range: 0.5–4MPa.
