Parker 777 vs. 722 Hose: Choosing the Right 4,000 PSI Solution

Parker 777 vs. 722 Hose: Choosing the Right 4,000 PSI Solution

When you’re specifying hydraulic hose for a high-pressure system, both the Parker 777 and Parker 722 series offer trusted 4,000 PSI constant working pressure—but they aren’t built the same. While the 722 has been a solid performer for years, Parker’s newer 777 hose brings modern improvements in size, flexibility, and temperature resistance that can make a real difference in your operation.

At Air Hydro Power, we carry both options in stock and can help you decide which hose is best suited for your application.

Parker 777 Hose: Lighter, Smaller, and Designed for Modern Systems

The Parker 777 is a next-generation, compact hose built to provide the same working pressure as legacy hoses in a smaller, more flexible form factor.

Key advantages:

  • Compact OD: Starts at .66 inches, making it easier to route in tight spaces
  • Lightweight: Starts at just 0.36 lbs
  • Tight Bend Radius: Just 2 inches, helping with installation and reducing hose stress
  • High Temperature Rating: Rated to 257°F, ideal for hotter systems
  • 43 Series Fittings Compatibility: Widely available and easy to install
  • 4,000 PSI Constant Pressure

Considerations: While it’s ideal for most systems, the compact size may not be necessary for larger or less space-restricted layouts.

Parker 722 Hose: Proven Durability with ISO-Certified Performance

The 722 remains a reliable solution, especially for heavy-duty systems that need ISO 18752 performance ratings.

Key benefits:

  • ISO 18752 BC & CC Performance Ratings: Meets international standards for demanding environments
  • Robust Construction: Built for rugged use
  • 4,000 PSI Constant Pressure

Specifications:

  • OD: Starts at .78 inches
  • Weight: Starts at 0.40 lbs
  • Bend Radius: 2.5 inches
  • Temperature Rating: Up to 212°F

Considerations: Larger and slightly heavier, the 722 may require more installation space and can be less flexible in compact systems.

Which Hose Should You Choose?

  • If your system demands modern flexibility, tighter installs, and higher temperature tolerance, the Parker 777 is a smart, forward-looking choice.
  • If you need ISO-certified durability and proven performance in heavy-duty conditions, the Parker 722 is still a solid performer.
