1504 NPTF Female to NPSM Female Swivel 45° Elbow | Hydraulic Fittings
The 1504 NPTF Pipe Female to NPSM Pipe Female Swivel 45° Elbow is a precision hydraulic adapter designed to provide a directional transition between two female-threaded pipe interfaces, from NPTF (National Pipe Taper Fuel) to NPSM (National Pipe Straight Mechanical), at a 45° angle with a swivel connection.
Connection Description & Function
- End 1: Female NPTF pipe thread
- End 2: Female NPSM pipe swivel thread
- Angle: 45° elbow
- Swivel female connection allows easier alignment during assembly
- Provides secure, reliable connection between two pipe systems at an angle
Applications
1504 Swivel Elbow fittings are suitable for a wide range of hydraulic systems, including:
- Lubrication systems
- Instrumentation and control lines
- High-pressure hydraulic circuits
- Industrial fluid power systems
- Mobile and construction equipment hydraulics
- Chemical processing systems
Pressure Ratings
- Working pressure: Up to 5,000 PSI
Suitable for extreme pressure applications, including systems operating at or near 5000 PSI
Key Features & Benefits
- Connects female NPTF to female NPSM swivel threads
- 45° elbow orientation for directional fluid routing
- Swivel design simplifies installation and alignment
- Leak-resistant performance in high-pressure systems
- Ideal for lubrication, instrumentation, and hydraulic use
Typical Use Cases
- Routing fluid lines through equipment at a 45° offset
- Aligning components with offset pipe connections
- Hydraulic manifolds and branch runs
- Mobile equipment hydraulic lines with directional constraints
- Industrial fluid distribution requiring angled connections
Installation Notes
- Ensure correct size matching for both NPTF and NPSM threads
- Swivel connection should be oriented before final tightening
- Use appropriate thread sealant where required by system design
- Tighten with standard hydraulic tools for secure, leak-free joints
This elbow fitting offers flexibility during installation, improved alignment between components, and a compact footprint while maintaining reliable sealing and pressure resistance for demanding hydraulic applications.
