The 5405 NPTF Pipe to Pipe Internal/External Expander is designed to adapt and transition between different NPTF pipe connection sizes within hydraulic systems. Its internal and external pipe-thread configuration provides a practical solution when an existing hydraulic run needs a change in pipe size.

Built in steel and designed around NPTF tapered pipe threads, the 5405 provides a compact connection for hydraulic and fluid-power assemblies where reliable pipe-size transitions are required. The collection lists working pressure up to 5,000 PSI.

NPTF Pipe-to-Pipe Expansion

The 5405 is specifically designed to expand or adapt pipe connections using NPTF threads.

This makes it useful when two compatible pipe connections have different nominal sizes and a direct transition is needed. Instead of combining multiple adapters, the expander provides the required size transition within one fitting.

The internal/external configuration allows the fitting to bridge different NPTF pipe-thread sizes while maintaining a straightforward connection path.

Internal and External NPTF Threads

The 5405 uses NPTF (National Pipe Taper Fuel) thread configurations.

Its internal and external thread arrangement allows the fitting to connect compatible NPTF components while transitioning between different pipe sizes.

Because NPTF threads are tapered, correct thread identification and proper installation are important for achieving the intended connection and sealing performance.

Pipe Size Transition Made Simpler

Hydraulic systems can sometimes require different pipe sizes within the same fluid circuit.

The 5405 provides a dedicated solution for these transitions, helping connect mismatched pipe sizes without unnecessarily rebuilding the surrounding hydraulic assembly.

This can be particularly useful when modifying an existing system, replacing older components, or adapting a hydraulic connection to a different pipe size.

Steel Construction

The 5405 collection lists the fitting material as steel, providing a strong body for demanding hydraulic and fluid-power connections.

Steel construction is well suited to hydraulic assemblies exposed to pressure, vibration, and regular operating loads.

The fitting is designed for practical installation within hydraulic pipe systems while maintaining a compact form factor.

Up to 5,000 PSI Working Pressure

The 5405 collection lists a working pressure of up to 5,000 PSI.

Actual pressure capability should always be evaluated according to the selected fitting size, mating components, installation method, and operating conditions.

For high-pressure systems, the complete assembly should be rated appropriately, including pipes, hoses, fittings, ports, and other connected components.

Tapered NPTF Sealing

The 5405 relies on its tapered NPTF thread configuration for the intended pipe connection.

Proper thread engagement and installation are important for achieving reliable sealing. The mating components should have compatible thread specifications and sizes.

Before installation, inspect the threads and verify that the fitting is appropriate for the intended hydraulic system.

Practical Solution for Existing Hydraulic Systems

The 5405 can be useful when modifying or upgrading an existing hydraulic installation.

Instead of replacing an entire pipe run simply because two connection sizes do not match, an appropriately selected expander can provide the transition required between the existing components.

This makes the fitting a practical option for hydraulic system modifications, repairs, and connection changes.

Installation Considerations

Proper installation is important when using an NPTF pipe expander.

Before installation:

  1. Confirm both required NPTF thread sizes.
  2. Verify which side of the expander connects to each component.
  3. Check compatibility of the mating threads.
  4. Inspect the threads before assembly.
  5. Use the appropriate thread-sealing method for the system.
  6. Tighten correctly without excessive torque.
  7. Verify that the complete assembly is suitable for the operating pressure.

Correct sizing is especially important because the primary purpose of the 5405 is to transition between different pipe connection sizes.

Why Choose the 5405?

The 5405 provides several practical features for hydraulic pipe transitions:

  • NPTF internal/external configuration
  • Pipe-to-pipe size expansion
  • Steel construction
  • Tapered NPTF threading
  • Compact transition design
  • Up to 5,000 PSI working pressure
  • Suitable for hydraulic and fluid-power systems
  • Multiple size combinations

Its purpose-built design makes it easier to adapt different NPTF pipe sizes within an existing hydraulic connection.

Selecting the Correct 5405

Before ordering, confirm the exact NPTF sizes required on both sides of the connection.

Check:

  • Internal NPTF thread size
  • External NPTF thread size
  • Required pipe-size transition
  • Mating component compatibility
  • Available installation space
  • Hydraulic system pressure requirements

The collection includes multiple combinations ranging from smaller pipe sizes through larger configurations, including reducing and expanding combinations.

5405 for Hydraulic Pipe Transitions

The 5405 is designed for situations where hydraulic pipe connections need to transition from one NPTF size to another.

Its internal/external configuration allows installers to adapt the connection without relying on multiple separate fittings. This can help simplify hydraulic assemblies and keep pipe transitions compact.

Gear House Hydraulics 5405

Gear House Hydraulics offers the 5405 NPTF Pipe to Pipe Internal/External Expander in multiple configurations.

The collection identifies the fitting as a precision-machined hydraulic component designed for pipe-size transitions within NPTF hydraulic systems. It is listed in steel and rated for working pressure up to 5,000 PSI.

Order 5405 NPTF Pipe Expander

When your hydraulic system requires a transition between different NPTF pipe sizes, the 5405 provides a compact internal/external expander designed specifically for that purpose.

Select the correct thread configuration, verify the mating components, and ensure the complete hydraulic assembly is suitable for the intended operating pressure.
