The 1504 NPTF Female × NPSM Female Swivel 45° Elbow is designed for hydraulic systems that require a 45-degree change in flow direction combined with swivel installation flexibility. The Female NPTF connection provides a tapered pipe-thread interface, while the Female NPSM swivel allows easier alignment and positioning during assembly.
Built from steel and designed for high-pressure hydraulic systems, the 1504 provides a practical connection solution where directional routing, thread compatibility, and installation flexibility are important.
Female NPTF × Female NPSM Swivel Connection
The 1504 combines two specific female pipe-thread configurations:
- Female NPTF pipe thread
- Female NPSM pipe swivel
- 45° elbow configuration
The Female NPTF side uses a tapered pipe thread, while the Female NPSM side uses a straight mechanical thread with swivel functionality.
This combination allows compatible hydraulic components with different pipe-thread configurations to be connected through one angled fitting. Always confirm the exact thread type and size before installation.
45° Elbow Configuration
The 1504 provides a 45-degree change in hydraulic line direction within the fitting itself.
This angled configuration can help route hydraulic lines around equipment, ports, manifolds, and other components where straight routing is not practical.
A 45° elbow can also provide a more gradual directional change than a 90° fitting, helping with hose positioning while maintaining a compact connection.
Female NPSM Swivel for Easier Alignment
The Female NPSM swivel is a key feature of the 1504.
The swivel connection allows the female end to rotate during assembly, giving the installer additional flexibility when positioning the connected component.
This can make installation easier in areas where access is limited or where the final hose orientation needs to be adjusted. Proper positioning before final tightening can also help avoid unnecessary twisting of connected components.
Steel Construction
The 1504 is listed with steel construction, providing a strong fitting body for hydraulic and industrial fluid-power systems.
Steel is well suited to hydraulic assemblies exposed to pressure, vibration, and regular operating loads. Proper sizing and installation remain important to ensure reliable performance within the complete hydraulic system.
The fitting should always be selected according to the requirements of the complete assembly rather than considered separately from the connected hose, tubing, fittings, and other components.
Up to 5,000 PSI Working Pressure
The 1504 collection lists a working pressure of up to 5,000 PSI.
This makes the fitting suitable for demanding high-pressure hydraulic systems when the selected configuration and complete hydraulic assembly are properly rated for the intended operating conditions.
Actual system capability depends on factors such as fitting size, connected components, line conditions, temperature, and operating environment. Always consider the pressure rating of the complete hydraulic assembly.
NPTF Female Connection
The first side of the 1504 uses a Female NPTF pipe thread.
NPTF stands for National Pipe Taper Fuel. It uses a tapered pipe-thread configuration designed for compatible pipe-thread connections and sealing applications.
The Female NPTF connection should be matched with the correct compatible 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 and positioning without requiring the connected component to remain fixed in one orientation.
45° Directional Change for Hydraulic Routing
A 45° elbow is useful when a hydraulic connection needs to change direction while maintaining a compact assembly.
The 1504 incorporates this directional change into the fitting itself, helping route fluid lines around equipment and other components.
This configuration can be useful for hydraulic manifolds, branch runs, mobile equipment lines, and other systems where the connection needs to be positioned at an angle.
Installation Considerations
Proper installation is important for achieving reliable performance from the 1504.
Before installation:
- Confirm the Female NPTF thread size.
- Confirm the Female NPSM swivel size.
- Verify compatibility with the mating components.
- Check available clearance around the 45° elbow.
- Position the swivel connection before final tightening.
- Use appropriate thread sealant where required by the system design.
- Use suitable hydraulic tools for installation.
- Avoid excessive torque that could damage the fitting or connected components.
- Confirm that the complete hydraulic assembly meets the required pressure conditions.
NPTF and NPSM are different thread configurations and should not be treated as interchangeable simply because their nominal sizes may appear similar.
Why Choose the 1504?
The 1504 combines several useful features in one hydraulic fitting:
- Female NPTF × Female NPSM Swivel connection
- 45° elbow configuration
- Steel construction
- Up to 5,000 PSI working pressure
- Swivel alignment during installation
- Compact angled fluid routing
- Suitable for high-pressure hydraulic systems
Combining the 45° directional change with a swivel connection can simplify installation where both routing and alignment are important.
Selecting the Correct 1504
Before ordering the 1504, verify the connection requirements on both sides of the fitting.
Pay particular attention to:
- Female NPTF thread size
- Female NPSM swivel size
- Required 45° orientation
- Mating component compatibility
- Available installation clearance
- Required working pressure
- Operating conditions of the hydraulic system
The 1504 collection includes multiple connection-size combinations, so selecting the correct configuration is important for achieving a proper fit within the hydraulic assembly.
