Sleeve metal hoses are made by covering a layer of cable-grade PVC material over the convex and concave surfaces of the core inside the wall of stainless steel or galvanized metal hoses. Due to their lightweight, excellent flexibility, strong attachment connections, electrical properties, and oil resistance, as well as splashwater protection, they are widely used in industries such as electricity, chemicals, metallurgy, light industry, and machinery. The sleeve metal hose specifications range from 6mm to 200mm, available in black or gray, with custom sizes and colors upon request. Sleeve metal hoses, commonly known in the industry as "snake skin hoses," use the metal hose as the core and cover it with a layer of cable-grade PVC material along the wall's convex and concave surfaces. Their lightweight, superior softness, ease of connection with equipment or accessories, oil resistance, and splashwater protection make them widely used in industries such as electricity, chemicals, metallurgy, and machinery. Standard colors include black and gray, with custom production available to meet customer needs.
