Interlock Fitting FAQs
What Are ORB Hydraulic Fittings?
ORB (O-Ring Boss) hydraulic fittings are a type of connector used in hydraulic systems. They feature a straight thread design and utilize an O-ring for sealing, providing a reliable and leak-free connection. This design eliminates the need for thread engagement to create a seal, reducing the risk of leaks and making them easier to install than traditional tapered thread fittings.
ORB fittings are commonly found in various applications, including mobile equipment, industrial machinery, and automotive systems.

ORB Hydraulic Fitting vs NPT
ORB hydraulic fittings come in a variety of types to suit different applications and system requirements.
- Straight Fittings: These are the most common type, used to connect hoses or pipes in a straight line. They are available in both male and female configurations.
- Elbows: These fittings allow for 90-degree bends in the hydraulic line, providing flexibility in system routing.
- Tees: These fittings create a branch in the hydraulic line, allowing for the connection of multiple components.
- Crosses: These fittings allow for the connection of four different lines at a single point.
- Swivels: These fittings incorporate a rotating joint, allowing for flexibility in the system and reducing stress on the hoses.
- Plugs: These fittings are used to seal off unused ports in a hydraulic system.
The specific type of ORB fitting chosen will depend on the requirements of the particular application, such as the desired flow path, pressure rating, and space constraints.
ORB Hydraulic Fitting vs JIC
ORB (O-Ring Boss) and JIC (Joint Industrial Council) are two common types of hydraulic fittings, each with distinct characteristics.
ORB fittings utilize a straight thread design and rely on an O-ring for sealing. This creates a reliable and leak-free connection, even in high-pressure applications. The O-ring seal also simplifies installation and increases reusability.
JIC fittings, on the other hand, employ a 37-degree flared thread. They achieve a seal through metal-to-metal contact between the flared surfaces. While JIC fittings are widely used, they can be more susceptible to leaks if not installed correctly or if the flared surfaces become damaged.
Key Differences:
- Sealing Mechanism: ORB uses an O-ring, JIC uses metal-to-metal contact.
- Thread Type: ORB has straight threads, JIC has 37-degree flared threads.
- Leak Resistance: ORB generally offers better leak resistance due to the O-ring seal.
- Installation: ORB fittings are typically easier to install and less prone to overtightening.
The choice between ORB and JIC fittings depends on the specific application requirements, including pressure demands, ease of installation, and desired level of leak resistance.
