The 1404 Male NPT × Female NPSM Swivel Straight is designed to connect tapered male NPT pipe threads with female NPSM swivel connections in hydraulic and fluid-power systems. Its straight configuration provides a direct connection path, while the swivel female end allows easier alignment during installation.
Built in steel and offered in a wide range of sizes, the 1404 is a practical choice for hydraulic, lubrication, instrumentation, and industrial fluid-transfer applications.
Male NPT × Female NPSM Swivel Connection
The 1404 combines two specific pipe connection types in one fitting:
- Male NPT connection
- Female NPSM swivel connection
- Straight configuration
This makes the fitting useful when equipment or hydraulic components use different pipe-thread configurations and require a direct connection between them.
Correct thread identification is important before installation. NPT and NPSM are different connection types and should not be treated as interchangeable simply because their nominal sizes may look similar.
Female NPSM Swivel for Easier Alignment
The swivel female end is one of the key advantages of the 1404.
Instead of forcing the connected component into a fixed orientation, the swivel design provides greater flexibility during assembly. This can help reduce alignment problems and unnecessary installation stress.
The swivel connection is particularly useful when working with hydraulic assemblies where access is limited or where the connected hose, tube, or component needs to be positioned precisely.
Straight Design for Direct Hydraulic Routing
The 1404 uses a straight fitting configuration, keeping both connection points aligned.
This makes it suitable for applications where the hydraulic line does not require a directional change. A straight adapter can also help keep the finished assembly compact by avoiding unnecessary elbows or additional fittings.
For pipe-to-pipe hydraulic connections, the 1404 provides a simple and practical configuration.
Steel Construction
Gear House Hydraulics lists the 1404 in steel, making it suitable for demanding hydraulic and industrial applications.
Steel construction provides a strong fitting body for applications exposed to hydraulic pressure, equipment vibration, and regular service conditions.
The fitting is also available across a broad range of connection sizes, making it easier to match the adapter to different hydraulic systems.
Up to 5,000 PSI Working Pressure
The 1404 collection lists a working pressure of up to 5,000 PSI, with actual working pressure depending on tube size, fitting size, and application conditions.
For high-pressure systems, the pressure rating of the complete hydraulic assembly should always be considered. The hose, tubing, fittings, mating ports, and other components should be suitable for the intended operating conditions.
Reduce Installation Stress
Getting hydraulic connections aligned correctly can be challenging when components are already installed in machinery.
The 1404 swivel design provides additional movement at the female connection during assembly. This can help prevent unnecessary force from being transferred to connected components and make threading easier in restricted spaces.
A properly aligned fitting also helps create a cleaner final hydraulic assembly.
Why Choose the 1404?
The 1404 is a practical choice when your application requires:
- Male NPT × Female NPSM Swivel connection
- Straight hydraulic routing
- Steel construction
- Female swivel flexibility
- Multiple size combinations
- Up to 5,000 PSI working pressure
- Hydraulic and industrial fluid-transfer capability
- Easier installation and alignment
Its combination of NPT and NPSM connections makes it useful for hydraulic systems where pipe-thread compatibility and installation flexibility are both important.
How to Select the Correct 1404
Before ordering, confirm both connection types and nominal sizes.
Check:
- Male NPT size required by the equipment.
- Female NPSM size required on the swivel side.
- Whether the application requires an equal-size or reducing adapter.
- Operating pressure of the complete hydraulic system.
- Available installation space.
- Compatibility of the mating components.
For example, the 1404-04-04 provides a 1/4-18 Male NPT connection and a 1/4-18 Female Pipe Swivel connection.
Do not select a fitting based only on nominal size. Confirm the actual thread type before installation.
1404 for Industrial Hydraulic Equipment
Industrial hydraulic equipment often combines components from different manufacturers, which can result in different connection requirements within the same system.
The 1404 provides a dedicated Male NPT to Female NPSM swivel transition, helping installers connect compatible components without unnecessarily adding multiple adapters.
Its straight configuration is useful where direct routing is preferred, while the swivel end provides additional flexibility during assembly.
Gear House Hydraulics 1404
Gear House Hydraulics offers the 1404 Male NPT × Female NPSM Swivel Straight in a broad range of steel configurations.
