5405 NPTF Pipe to Pipe Internal/External Expander | Hydraulic Fittings
Description
The 5405 NPTF Pipe to Pipe Internal/External Expander series consists of precision-machined hydraulic fittings designed to expand or adapt pipe connections within NPTF (National Pipe Taper Fuel) threaded hydraulic systems. These expanders provide reliable transitions between different pipe sizes while maintaining pressure integrity in demanding fluid power environments.
Connection Description & Function
- Type: Internal and External Pipe Expander
- Thread Standard: NPTF (National Pipe Taper Fuel)
- Designed to connect and adapt pipe runs by converting or expanding pipe thread sizes
- Provides positive sealing using tapered NPTF threads
- Suitable for fluid power systems where pipe size transitions are required
Applications
5405 NPTF Pipe Expanders are commonly used in:
- Lubrication distribution systems
- Instrumentation and control fluid lines
- High-pressure hydraulic circuits
- Industrial and mobile hydraulic equipment
- Construction machinery hydraulic systems
Pressure Ratings
- Working pressure: Up to 5,000 PSI
Suitable for extreme pressure applications, including systems operating at or above 5000 PSI when properly selected and installed
Key Features & Benefits
- Expands or adapts pipe connections with NPTF threads
- Provides secure sealing via tapered pipe engagement
- Suitable for lubrication, instrumentation, and high-pressure hydraulics
- Excellent mechanical strength and leak resistance
- Ideal for transitions between mismatched pipe sizes within hydraulic runs
Typical Use Cases
- Adjusting pipe sizes in hydraulic manifold blocks
- Adapting legacy pipe networks to new system requirements
- Bridging between different pipe configurations
- Hydraulic system retrofits requiring reliable transitions
- Industrial and mobile fluid power applications
Ideal for use in lubrication systems, instrumentation lines, and high-pressure hydraulic applications, these expanders offer robust performance and secure sealing where pipe size transitions are required.
