HYDRAULIC FITTINGS - GetHydraulics

Hydraulic Fittings Built for Performance and Reliability

At Union Hydraulics, we know hydraulic fittings might look like small components—but they play a critical role in the performance and safety of your entire hydraulic system. Whether you’re running heavy equipment in the field, maintaining industrial machinery, or building a new hydraulic assembly from scratch, the right fittings make the difference between smooth operation and costly downtime.

If your system depends on pressure, flow, and reliability, your fittings matter more than you think.

What Are Hydraulic Fittings and Why Do They Matter?

Hydraulic fittings are the connectors that join hoses, pipes, tubes, and other components within a hydraulic system. Their job is simple in theory: create a secure, leak-free connection. In practice, that connection must withstand extreme pressure, vibration, temperature changes, and environmental exposure.

When fittings fail, you don’t just lose fluid—you lose productivity. Leaks can lead to system inefficiencies, contamination, safety hazards, and expensive repairs. That’s why choosing the correct fitting is not just about size—it’s about compatibility, pressure rating, material, and application.

At Union Hydraulics, we help you get it right the first time.

Types of Hydraulic Fittings We Supply

Hydraulic systems aren’t one-size-fits-all, and neither are fittings. We supply a wide range of hydraulic fittings to match your equipment and application, including:

  • JIC fittings
  • ORFS (O-Ring Face Seal) fittings
  • NPT and NPTF pipe fittings
  • BSP fittings
  • Metric fittings
  • Flange fittings
  • Quick disconnect couplings
  • Adapters and reducers

Each fitting style serves a specific purpose. For example, JIC fittings are commonly used in high-pressure applications and are known for their 37-degree flare seal. ORFS fittings are excellent for vibration-heavy environments because the O-ring provides superior leak protection. Pipe thread fittings are often used in general industrial applications where taper threads create the seal.

If you’re not sure which type you need, that’s exactly what we’re here for.

Materials That Match Your Environment

Hydraulic fittings must stand up to the conditions they’re installed in. We supply fittings in a variety of materials to suit different operating environments:

  • Carbon steel for strength and durability
  • Stainless steel for corrosion resistance
  • Brass for lower-pressure or specialized applications
  • Specialty coatings for added protection

For example, if your equipment operates outdoors or in marine environments, corrosion resistance becomes critical. In food processing or chemical environments, material compatibility matters even more. We’ll help you select the right material to extend the life of your system.

Pressure Ratings and Performance

Hydraulic systems operate under serious pressure—often thousands of PSI. Using a fitting that isn’t properly rated for your system can cause premature failure or dangerous blowouts.

When you work with Union Hydraulics, we make sure:

  • The fitting matches your system’s pressure requirements
  • The thread type is correct
  • The sealing method is appropriate
  • The hose and fitting are compatible

We take the guesswork out of the process so you can operate with confidence.

Common Applications

Hydraulic fittings are used across a wide range of industries and equipment, including:

  • Construction equipment
  • Forestry machinery
  • Agricultural equipment
  • Manufacturing and automation systems
  • Material handling equipment
  • Hydraulic presses and power units

Whether you’re repairing a cylinder line on a skid steer or building a complete hydraulic power system, the right fitting ensures reliability and safety.

Why Buy Hydraulic Fittings from Union Hydraulics?

At Union Hydraulics, we don’t just sell parts—we solve problems.
We understand hydraulic systems from the inside out. Our team works with maintenance managers, service technicians, plant engineers, and equipment operators every day. We know how frustrating it is to deal with mismatched threads, mystery leaks, or fittings that don’t quite seat properly.

When you call us, you’re talking to professionals who understand:

  • Thread identification
  • Cross-referencing part numbers
  • System troubleshooting
  • Pressure and flow considerations
  • Application-specific requirements

We focus on getting you exactly what you need so you can get back up and running quickly.

Not Sure Which Hydraulic Fitting You Need?

Hydraulic fittings can be confusing. Metric vs. SAE. JIC vs. ORFS. Straight thread vs. tapered thread. Even experienced technicians sometimes need confirmation.
If you’re unsure:

  • Share a photo of the fitting
  • Provide measurements (thread diameter and pitch)
  • Tell us the equipment make and model
  • Describe the application and pressure

We’ll walk you through it and make sure you get the correct part.

Keep Your System Running Strong

Your hydraulic system is only as reliable as its connections. High-quality fittings ensure leak-free performance, maintain system pressure, and protect your investment in hoses, cylinders, pumps, and valves.

At Union Hydraulics, we’re here to help you make the right choice the first time. If you have any questions or concerns about which hydraulic fitting you need, give us a call. We’re happy to review your application and guide you in the right direction.
