The 1502 NPTF Female × NPSM Female Swivel 90° Elbow is designed for hydraulic systems that require a 90-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 during assembly.
Manufactured from carbon steel with a zinc-plated finish, the 1502 provides a durable connection solution for hydraulic and fluid-power systems where directional routing and installation flexibility are important.
Female NPTF × Female NPSM Swivel Connection
The 1502 combines two specific female pipe-thread configurations:
- Female NPTF pipe thread
- Female NPSM swivel connection
- 90° elbow configuration
The NPTF side uses a tapered pipe thread, while the NPSM side uses a straight mechanical thread with swivel functionality.
Because NPTF and NPSM are different connection configurations, the thread type and connection size should always be confirmed before installation.
90° Elbow Configuration
The 1502 provides a 90-degree change in hydraulic line direction within the fitting itself.
This configuration can help route hoses and hydraulic lines around equipment, ports, or other components where a straight connection would not provide sufficient clearance.
Using a dedicated 90° elbow can also help create a cleaner and more organized hydraulic assembly without requiring an additional directional fitting.
Female NPSM Swivel for Easier Alignment
The Female NPSM swivel is an important feature of the 1502.
The swivel connection can rotate during assembly, providing additional flexibility when positioning the connected component. This can make installation easier where access is limited or where the final hose orientation needs to be adjusted.
The swivel design can also help reduce unnecessary twisting of connected hydraulic components during installation.
Carbon Steel Construction
The 1502 is manufactured from carbon steel and features a zinc-plated finish.
Carbon steel provides a strong fitting body for hydraulic assemblies exposed to pressure, vibration, and regular equipment operation. The zinc-plated finish provides additional surface protection against corrosion in suitable operating environments.
Proper fitting selection and installation remain important for reliable performance within the complete hydraulic system.
Zinc-Plated Finish
The zinc-plated finish adds a protective surface layer to the steel fitting.
This finish is useful for hydraulic components that may be exposed to demanding working conditions. The actual suitability of the fitting should always be considered based on the surrounding environment and operating conditions.
NPTF Female Connection
The first side of the 1502 uses a Female NPTF connection.
NPTF stands for National Pipe Taper Fuel. It uses a tapered pipe-thread configuration intended for compatible dryseal pipe-thread connections.
The Female NPTF side should be matched with the correct compatible male thread. Confirm the actual thread specification and nominal size before installation rather than selecting a fitting based only on nominal pipe dimensions.
NPSM Female Swivel Connection
The opposite side uses a Female NPSM swivel connection.
NPSM stands for National Pipe Straight Mechanical. Unlike the tapered NPTF connection, NPSM uses a straight mechanical thread configuration.
The swivel feature allows the connection to rotate during assembly, helping with alignment and positioning while the fitting is installed.
Directional Change for Hydraulic Routing
A 90° elbow is useful when a hydraulic line needs to change direction immediately after the connection point.
The 1502 incorporates this directional change into the fitting, helping reduce unnecessary hose bends and simplifying routing around hydraulic equipment.
The compact elbow configuration can be particularly useful where installation space and hose positioning need to be considered.
Installation Considerations
Proper installation is important for reliable performance from the 1502.
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 90° elbow.
- Position the swivel connection correctly before final tightening.
- Use appropriate tools and avoid excessive torque.
- Ensure the complete hydraulic assembly is suitable for the intended operating 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 1502?
The 1502 combines several useful connection features in one hydraulic fitting:
- Female NPTF × Female NPSM Swivel connection
- 90° elbow configuration
- Carbon steel construction
- Zinc-plated finish
- Swivel alignment during installation
- Compact directional routing
- Suitable for high-pressure hydraulic systems
Combining the 90° directional change with a swivel connection can simplify installation where both line routing and component alignment are important.
Selecting the Correct 1502
Before ordering the 1502, verify the connection requirements on both sides of the fitting.
Pay particular attention to:
- Female NPTF thread size
- Female NPSM swivel size
- Required 90° orientation
- Mating component compatibility
- Available installation clearance
- Hydraulic system operating requirements
The 1502 collection includes multiple connection-size combinations, so selecting the correct configuration is important for achieving a proper fit within the hydraulic assembly.
