The 5404 Male NPT × Male NPT Hex Pipe Nipple is a straight hydraulic pipe fitting designed to connect two female NPT ports. Its male-to-male configuration provides a direct connection between threaded components, while the hexagonal body makes installation and tightening easier.
The fitting is listed in steel with a high-strength carbon steel construction, making it a practical choice for hydraulic piping, fluid-transfer assemblies, and industrial equipment.
Male NPT × Male NPT Connection
The 5404 uses a straightforward Male NPT × Male NPT configuration.
Both ends feature male NPT threads, allowing the nipple to connect two compatible female NPT ports. This makes the fitting useful when a direct threaded connection is required without changing the flow direction.
Correct thread identification is important before installation. Verify the NPT thread size and compatibility of both mating female ports before selecting the fitting.
Hex Body for Easier Installation
The hexagonal center body is one of the defining features of the 5404.
The hex shape provides a convenient surface for a wrench, making the fitting easier to install and tighten compared with a smooth round-body nipple.
This design can also make removal and servicing more manageable when the fitting needs to be replaced or repositioned.
Straight Hydraulic Connection
The 5404 uses a straight adapter configuration, keeping both NPT connections aligned on the same axis.
This direct configuration is useful when two female threaded ports need to be joined without introducing a directional change.
The straight design also helps maintain a compact hydraulic assembly while providing a simple connection path between the two components.
Carbon Steel Construction
Gear House Hydraulics lists the 5404 with high-strength carbon steel construction.
Carbon steel provides a strong fitting body for hydraulic and fluid-transfer systems where the connection may be exposed to pressure, vibration, and regular equipment operation.
The page also identifies a corrosion-resistant surface, adding protection for suitable operating environments.
NPT Male Pipe Threads
NPT stands for National Pipe Thread. The male NPT threads on the 5404 are designed to connect with compatible female NPT ports.
The tapered thread configuration helps create the intended threaded connection when correctly matched and installed.
Always confirm the exact thread specification before installation. A nominal pipe size alone is not enough to guarantee thread compatibility.
Direct Connection Between Female NPT Ports
The 5404 is particularly useful when two components both have female NPT ports and need to be connected directly.
Instead of combining multiple adapters, a Male NPT × Male NPT pipe nipple can provide the required threaded bridge between the two components.
This keeps the connection simple and helps avoid unnecessary fittings in the assembly.
Installation Considerations
Proper installation helps maintain reliable performance from the 5404.
Before installation:
- Confirm both mating ports use compatible Female NPT threads.
- Verify the required nominal thread size.
- Check the available clearance around the hex body.
- Apply the appropriate thread sealing method for the system.
- Tighten using the hex section of the fitting.
- Avoid excessive torque that could damage the fitting or mating components.
Thread sealant requirements can vary according to the application, fluid, pressure, and mating components, so use an appropriate sealing method for the complete hydraulic system.
