SAE J525 Welded Hydraulic Tubing is a versatile low-carbon steel tubing designed for various hydraulic applications. The tubing is specifically annealed to facilitate bending and flaring, making it suitable for use in pressure lines where high-quality tubing is essential. Its applications span across industries such as Heavy Equipment, Agriculture, Off-Road Vehicles, Automotive, Steering and Transmission components, Process and Utility, and other Hydraulic systems.

 

The manufacturing process of J525 high-pressure tubing involves multiple cold-drawn reductions, intermediate anneals, and a final dead-soft anneal after sizing. This meticulous process ensures the production of tubing that is consistently of high quality, providing ease of bending and flaring.

 

Similar to J524, J525 shares common chemical and mechanical properties and finds application in hydraulic systems. The primary distinction lies in the fact that J525 is welded from flat stock. For applications where flaring is a requirement, J524 Seamless tubing is typically preferred. Nevertheless, both J524 and J525 exhibit high quality and comparable specifications.

 

Key specifications for SAE J525 include conformity to SAE J-525 standards, as well as adherence to ASTM A-214 (Except Average Wall), ASME SA-214 (Except Average Wall), Addenda EN10204 3.1.B, PED Certification, and dual certification as Fluidline. The tubing is available in uniform lengths and is characterized by its OD x ID dimensions, providing consistency and reliability.
