The Society of Automotive Engineers (SAE) plays a vital role in setting the standards for hydraulic hoses. These standards serve essential purposes such as:

1. Safety and reliability: SAE standards ensure that hydraulic hoses meet a minimum standard for safety, reliability, and performance. By adhering to certain guidelines, manufacturers can make hoses that withstand pressure, temperature fluctuations, and exposure to certain fluids.
2. Interchangeability standards promote uniformity. When you need to replace a hydraulic hose or fitting, all you need to know is if that fitting or hose meets or exceeds SAE standards. You don't need to purchase from the same manufacturer to get your system up and running again.
3. Application-specific designs of a hydraulic system have varying requirements. SAE standards categorize hoses based on construction, pressure ratings, and intended application. For example,

• • SAE 100R1 is suitable for widespread use at high pressure.
  • SAE 100R2 is suitable for more demanding applications.
