The 1405 NPTF Female × NPSM Female Swivel Straight Adapter connects female NPTF pipe threads to a female NPSM swivel connection in a straight configuration. Its swivel design helps with alignment and tightening during installation, making it a practical choice for hydraulic and fluid-power assemblies.
Built in steel and rated for working pressures up to 5,000 PSI, the 1405 provides a dependable connection solution where different pipe-thread configurations need to be joined in a compact straight adapter.
Female NPTF × Female NPSM Swivel Connection
The 1405 combines two specific female pipe-thread connections:
- Female NPTF pipe thread
- Female NPSM pipe swivel
- Straight adapter configuration
This combination allows compatible hydraulic components with different pipe-thread requirements to be connected through one fitting.
The NPTF side uses a tapered pipe thread, while the NPSM side uses a straight mechanical swivel connection. Confirming the exact thread type before installation is important because NPTF and NPSM are different connection configurations.
Female NPSM Swivel for Easier Alignment
The Female NPSM swivel is a key feature of the 1405 adapter.
The swivel end can rotate during assembly, giving the installer additional flexibility when aligning the connected component. This can make installation easier where fixed pipe connections are difficult to position correctly.
The swivel design can also help reduce unnecessary twisting and installation stress on connected components.
Straight Adapter Configuration
The 1405 uses a straight-through configuration, keeping both connection points aligned.
This makes it useful where a direct connection is preferred without changing the direction of the hydraulic line. The straight body also provides a simple, compact connection between compatible pipe-thread components.
For hydraulic assemblies where alignment and connection access are important, the swivel feature adds flexibility without changing the overall straight configuration.
Steel Construction
The 1405 is listed with steel construction, providing a strong fitting body for hydraulic and industrial fluid-power systems.
Steel is well suited to hydraulic assemblies that experience pressure, vibration, and regular operating loads. Proper sizing and installation remain important to ensure the fitting performs correctly within the complete hydraulic system.
Up to 5,000 PSI Working Pressure
The 1405 collection lists a working pressure of up to 5,000 PSI. Actual pressure capability can vary according to fitting size, line conditions, and the operating environment.
For high-pressure hydraulic systems, always consider the rating of the complete assembly, including hoses, tubing, fittings, ports, and other connected components.
NPTF Female Pipe Connection
The first side of the 1405 uses a Female NPTF pipe thread.
NPTF stands for National Pipe Taper Fuel. It uses a tapered thread configuration designed to provide a dryseal connection when properly matched with compatible male fittings.
The NPTF connection should be matched with the correct male thread size and specification. Avoid selecting the fitting based only on nominal pipe size without confirming the actual thread type.
NPSM Female Swivel Connection
The opposite side uses a Female NPSM swivel connection.
NPSM stands for National Pipe Straight Mechanical. Unlike the tapered NPTF side, NPSM uses a straight mechanical thread configuration.
The swivel feature allows the female connection to rotate during assembly, helping achieve proper alignment while reducing the need to reposition connected components.
Installation Considerations
Proper installation is important for achieving reliable performance from the 1405.
Before installation:
- Confirm the Female NPTF thread size.
- Confirm the Female NPSM swivel connection size.
- Verify that the mating male fittings use the correct compatible thread types.
- Check the pressure requirements of the complete hydraulic assembly.
- Use appropriate tools and avoid excessive torque.
- Use a backup wrench on the swivel end when required to prevent unnecessary torque transfer.
The Gear House Hydraulics page also notes that thread sealant or tape may be required on NPTF connections depending on sealing requirements and mating components.
Why Choose the 1405?
The 1405 is a practical choice when your hydraulic assembly requires:
- Female NPTF × Female NPSM Swivel connections
- Straight hydraulic routing
- Steel construction
- Swivel alignment during installation
- A compact pipe-thread adapter
- Working pressure up to 5,000 PSI
- Connection between different pipe-thread configurations
Its combination of a female NPTF port and female NPSM swivel provides flexibility for hydraulic systems where connection compatibility and installation alignment both matter.
Selecting the Correct 1405
Before ordering the 1405, verify the connection requirements on both sides of the hydraulic assembly.
Pay particular attention to:
- Female NPTF thread type
- Female NPSM swivel thread type
- Nominal connection size
- Required pressure rating
- Compatibility with the mating male fittings
- Available installation space
Correct thread identification helps prevent mismatched connections and unnecessary installation problems.
1405 for Hydraulic Assemblies
Hydraulic systems can include components with different pipe-thread configurations, especially when equipment combines components from different manufacturers or hydraulic standards.
The 1405 provides a dedicated Female NPTF to Female NPSM swivel connection in a straight configuration. The swivel end provides additional alignment flexibility, while the steel body is suited to demanding hydraulic and fluid-power environments.
