6900 - SAE O-Ring Boss ORB Male x NPTF Pipe, Female Swivel NPSM Adapter

The 6900 O-Ring to NPTF Pipe Swivel connects a male SAE O-Ring Boss (ORB) port to a female NPTF pipe connection in hydraulic and fluid transfer systems. Its straight adapter design combines dependable ORB sealing with a swivel pipe connection that makes installation and alignment easier.

Male ORB × Female NPTF Connection

The 6900 is designed for systems that need to connect two different hydraulic thread configurations. One side uses a Male ORB connection, while the other provides a Female NPTF swivel connection.

This configuration makes the 6900 useful when hydraulic equipment, valves, pumps, cylinders, or other components use ORB ports while the connected piping or component requires an NPTF connection.

Swivel Design for Easier Installation

One of the key advantages of the 6900 is its female pipe swivel design. The female connection can rotate independently during assembly, helping installers position the connection without unnecessarily twisting the hose or tubing.

That extra flexibility can be especially useful when working around tight equipment layouts or when connection alignment is difficult.

ORB O-Ring Sealing

The male ORB side uses an O-ring sealing connection designed to provide a reliable interface when correctly matched and installed.

ORB connections are commonly used in hydraulic systems where controlled sealing and accurate connection positioning are important. The 6900 combines this sealing configuration with a female NPTF swivel connection for added installation flexibility.

Steel Hydraulic Construction

The 6900 collection is listed by Gear House Hydraulics in steel, providing a practical material choice for demanding hydraulic and fluid-power applications.

The combination of steel construction, ORB sealing, and a swivel pipe connection makes this adapter suitable for a variety of industrial and mobile hydraulic equipment.

Straight Adapter Configuration

The 6900 uses a straight adapter configuration, keeping the connected ports in line while allowing the female pipe side to swivel.

This design is useful where the system needs a direct connection rather than a 45° or 90° directional change. It can also help simplify routing when component orientation already provides the required flow direction.

Simplify Hydraulic Line Routing

Hydraulic systems often contain multiple components packed into limited equipment space. A fixed adapter may force the installer to reposition a hose, tube, or connected component just to achieve proper alignment.

The 6900 helps address that problem with its rotating female pipe connection. The connection can be positioned during assembly without requiring unnecessary twisting of the connected hose or tubing.

That can make installation more practical and help keep hydraulic routing organized.

Why Choose the 6900 O-Ring to NPTF Swivel?

The 6900 is a practical choice when your hydraulic application requires:

• Male ORB to Female NPTF connection
• Female pipe swivel functionality
• Straight adapter configuration
• O-ring sealing on the ORB side
• Steel construction
• Multiple connection sizes
• Easier installation and alignment
• Hydraulic fluid transfer capability

Rather than adding multiple adapters to achieve the required connection arrangement, the 6900 provides the ORB-to-NPTF combination in one fitting.

Selecting the Correct 6900

Before ordering, confirm both sides of the required connection.

The first size identifies the Male ORB side, while the second corresponds to the Female NPTF swivel side. Make sure the thread type, nominal size, and mating components match the requirements of your hydraulic system.

For example, a 6900-08-08 connects an 08-size ORB side with an 08-size pipe-side connection. Reducing combinations are available when the two connection sizes are different.

A Practical Adapter for Hydraulic Systems

When an application combines ORB equipment with NPTF pipe-thread components, the right adapter can make installation considerably easier. The 6900 provides both the required connection transition and a swivel feature for improved positioning.

Its straight configuration keeps the connection compact while the rotating female pipe side helps installers work around equipment access and alignment challenges.
