The 6815 O-Ring Adjustable Street Elbow 90° is designed for hydraulic systems that need a compact 90° connection between Male SAE O-Ring Boss (ORB) and Female ORB ports. Its street-elbow configuration makes it useful where hydraulic connections need to change direction without adding unnecessary adapters or taking up excessive installation space.
With steel construction, ORB sealing, and multiple size combinations, the 6815 provides a practical connection solution for hydraulic equipment, machinery, manifolds, valves, pumps, and other fluid-power applications. Gear House Hydraulics currently lists the 6815 in steel with multiple equal and reducing size options.
Compact 90° Hydraulic Connection
The 6815 is designed to solve a common hydraulic routing problem: a connection needs to turn 90° while keeping the assembly compact.
Instead of forcing a hose or tube to make a tight bend directly from the port, the elbow establishes the direction at the fitting itself.
This makes the 6815 useful when working around:
- Hydraulic valve blocks
- Pumps and manifolds
- Cylinders
- Machinery frames
- Compact equipment compartments
- Restricted hydraulic installation areas
The 90° configuration can help create a cleaner and more controlled hydraulic line layout.
Male ORB x Female ORB Configuration
The 6815 connects two compatible ORB ports using different connection genders:
- Male SAE ORB
- Female SAE ORB
- 90° elbow configuration
- O-ring sealing system
The Male ORB side connects to a compatible female ORB port, while the Female ORB side accepts a compatible male ORB connection.
This makes the fitting useful for ORB-based hydraulic systems where a direct 90° connection is needed.
Adjustable Street Elbow Design
The street-elbow configuration is particularly useful when hydraulic components are installed close together.
A compact elbow can help position the connected hydraulic line away from equipment, brackets, frames, or other components.
The 6815 can help when:
- A straight fitting would create poor routing
- A 90° connection is required
- Available installation space is limited
- Two ORB components need to be connected
- Hydraulic line direction needs to change close to a port
- A compact fitting arrangement is preferred
This makes the 6815 a practical option for equipment where routing space cannot be wasted.
O-Ring Boss Sealing
The O-Ring Boss (ORB) connection uses an elastomeric O-ring to create the sealing interface between the fitting and mating port.
This sealing arrangement is designed for compatible ORB hydraulic connections and helps provide a reliable seal when the fitting is correctly selected and installed.
Before installation, inspect the O-ring and sealing surfaces for damage, contamination, or wear. Always confirm the correct ORB size and follow the appropriate installation procedure.
Steel Construction
Gear House Hydraulics lists the 6815 as a steel hydraulic fitting.
Comparable 6815 manufacturer specifications identify the fitting as forged carbon steel with trivalent zinc plating. The same specification lists NBR (Buna-N) as the standard O-ring material, with Viton available upon request.
This construction is intended for demanding hydraulic service where fitting strength and corrosion resistance are important.

Why Use a 6815 Street Elbow?
The 6815 is designed for situations where a straight ORB connection does not provide the required direction.
Its Male ORB x Female ORB 90° configuration allows two compatible ORB connections to be joined while changing the line direction.
Choose a 6815 when you need to:
- Connect Male ORB to Female ORB
- Create a 90° hydraulic turn
- Maintain a compact installation
- Work around equipment obstructions
- Reduce unnecessary adapter combinations
- Improve hydraulic line positioning
Selecting the Correct 6815
Before ordering, verify both connection sizes.
Male ORB Size:
Match the male ORB size to the compatible hydraulic port.
Female ORB Size:
Confirm the female ORB size matches the male ORB component being connected.
Elbow Direction:
The 6815 provides a 90° change in direction.
Installation Clearance:
Check the available space around the fitting and connected components.
System Requirements:
Confirm pressure, temperature, hydraulic fluid compatibility, and complete assembly requirements.

Frequently Asked Questions
What is a 6815 O-Ring Adjustable Street Elbow?
The 6815 is a 90° Male ORB x Female ORB hydraulic elbow designed for compact directional routing between compatible O-Ring Boss connections.
What connections does the 6815 have?
The 6815 uses a Male SAE ORB connection and Female SAE ORB connection.
What angle is the 6815?
The 6815 is a 90° elbow, allowing the hydraulic connection to change direction without requiring a separate directional adapter.
Does the 6815 use O-ring sealing?
Yes. The ORB connection uses an O-ring sealing arrangement. The referenced manufacturer specification lists NBR (Buna-N) as the standard O-ring material.
What material is the 6815 made from?
Gear House Hydraulics lists the 6815 as steel. The referenced manufacturer specification identifies forged carbon steel construction.
What sizes are available?
Gear House currently lists multiple sizes from 1/4 × 1/4 through 1 × 1, including reducing combinations such as 1/4 × 3/8, 3/8 × 1/2, and 3/4 × 5/8.
Where are 6815 elbows used?
They are suitable for hydraulic hose assemblies, pumps, valves, cylinders, manifolds, agricultural machinery, construction equipment, mobile hydraulics, and industrial fluid-power systems.
Why use a 90° ORB street elbow?
A 90° street elbow changes the hydraulic line direction directly at the connection point, helping keep routing compact when a straight fitting would not suit the installation.
Is the 6815 suitable for demanding hydraulic applications?
The 6815 is an ORB hydraulic fitting intended for hydraulic service. Always verify the pressure capability of the exact size and complete hydraulic assembly before installation.
