Introducing our SAE J525 Welded Hydraulic Tubing, thoughtfully designed to meet the demanding requirements of hydraulic systems across various industries. Our tubing stands out for its exceptional quality, versatility, and reliability in critical applications. Let’s explore the key features and applications that make SAE J525 the preferred choice.

As a leading supplier and stockist of J525 Welded Hydraulic Tubing in India, we take pride in delivering high-quality products with comparable specifications. Our tubes feature a carefully balanced chemical composition, including manganese, phosphorus, and sulfur, ensuring enhanced yield strength and hardness for long-lasting durability.

At SA179 Tube, we prioritize customer satisfaction by offering full customization options for SAE J525 Steel Tubing. Clients can tailor parameters such as outer diameter, wall thickness, and surface finishes to meet their specific requirements.

Key Features:

  1. Low-Carbon Steel Construction:
    • SAE J525 Hydraulic Tube is constructed from low-carbon steel, ensuring a balance of strength and flexibility. This makes it ideal for applications requiring precise bending and flaring.
  2. Annealed for Enhanced Properties:
    • The tubing undergoes annealing processes that enhance its properties, making it well-suited for bending, flaring, forming, and brazing. This results in tubing that meets high-quality standards.
  3. Versatile Applications:
    • SAE J525 finds applications in a wide range of industries, including Heavy Equipment, Agriculture, Off-Road Vehicles, Automotive, Steering and Transmission components, Process and Utility, and various hydraulic systems.
  4. Manufacturing Excellence:
    • Our high-pressure tubing undergoes a meticulous manufacturing process involving cold-drawn reductions, intermediate anneals, and a dead-soft anneal after final sizing. This process ensures consistency and high quality, making the tubing easy to bend and flare.

Similar to J524, SAE J525 shares identical chemical and mechanical properties, making them both suitable for hydraulic applications. The key distinction lies in the manufacturing process, as J525 starts as flat stock. When flaring is a requirement, J524 Seamless is often preferred, although both offer high quality and comparable specifications.

SAE J525 Hydraulic Tubing is the go-to choice for pressure lines in applications demanding superior tubing qualities. Its versatility makes it a reliable solution for Heavy Equipment, Agriculture, Automotive, and various hydraulic systems where precision and durability are paramount.

Choose precision and reliability for your hydraulic applications with SAE J525 Hydraulic Tube from SA179 Tube. Our commitment to quality, customization, and adherence to industry standards makes us your trusted partner for hydraulic solutions.
