FAQs
SAE J525 is a specification for cold-worked, annealed electric resistance welded low-carbon steel tubing, used for hydraulic lines and applications requiring tubing that can be easily flared and bent.
The main difference between J524 and J525 tubing is their manufacturing process and application suitability. J524 tubing is cold-drawn and seamless, ideal for hydraulic pressure lines, while J525 is welded and annealed, making it suitable for applications requiring high-quality tubing for bending, flaring, and brazing.
In North America, the standard for hydraulic tubing is often SAE J517, which specifies general, dimensional, and performance requirements for commonly used hydraulic hoses in both mobile and stationary equipment.
