Hydraulic tubes serve as the essential pressure-bearing components in fluid power systems, engineered for safe delivery of high-pressure hydraulic oil. Manufacturing processes maintain strict control over mechanical properties including tensile and yield strength to prevent tube failure, while ensuring precise dimensional tolerances for leak-free connections with ferrules and flared joints. The smooth, clean inner wall minimizes flow resistance and protects precision system components.

TP304L stainless steel provides optimal balance between performance and cost for conventional hydraulic fluid systems. It delivers adequate corrosion resistance for non-aggressive environments while offering excellent cold bending and flaring properties for complex piping layouts. Superior weldability and cost-effectiveness make it ideal for industrial and mobile equipment hydraulic applications.

Clean ID (inner diameter) ensures the tube interior is free from drawing lubricants, metal shavings, and contaminants. These particles can damage pumps, valves, and cylinders, causing system failure and costly downtime. Our hydraulic tubing undergoes specialized treatment and inspection to maintain high inner wall cleanliness for effective equipment protection.

304L polished hydraulic tubing serves as the primary component in numerous fluid systems across industrial machinery, engineering equipment, and agricultural vehicles. It is commonly employed as fuel lines, lubricating oil lines, and fluid delivery systems in automotive and marine applications, providing reliable, clean, and economical performance for smooth system operation.

To preserve inner bore cleanliness and surface finish from factory to installation, we implement meticulous protective packaging. Each polished tube is individually wrapped in plastic protective bags to isolate dust and moisture. Both tube ends are sealed with plastic caps to prevent contamination during transport and storage, with secure bundling in sturdy plywood boxes.
