This 400PSI textile cord reinforced mining hose features an abrasion-resistant inner tube perfectly adapted for underground water and air delivery. The intermediate multi-layer, high-density textile cord braided reinforcement ensures uniform stress distribution, achieving a rated working pressure of up to 400PSI. It offers excellent impact and stretch resistance with stable pressure containment, effectively preventing hose bursts. The thickened outer cover is highly resistant to gravel abrasion, underground moisture and corrosion, and long-term sun aging. The hose body is flexible, easy to drag and bend, and highly resistant to cracking from repeated rolling or crushing. Safe and durable, it is ideally suited for mining scenarios such as underground ventilation, drainage, and high-pressure fluid delivery for pneumatic equipment.
