DELPHI FITTINGS
Part Number: 1504
NPTF Pipe Female x NPSM Pipe Swivel Female 45° Elbow
Product Overview
The Delphi Fittings Part 1504 is a 45° elbow adapter designed to connect two male NPTF (National Pipe Taper Fuel / Dryseal) threaded pipes or fittings at a 45-degree angle, incorporating the convenience of a swivel on one end. This fitting features a female NPTF pipe thread on one end and a female NPSM (National Pipe Straight Mechanical) pipe swivel on the other. The female NPTF end provides a reliable Dryseal metal-to-metal connection with a mating male NPTF fitting. The female NPSM swivel end allows for easy orientation and tightening onto another male NPTF (or NPT) fitting without the need to rotate the elbow body or the first connected component, thus preventing stress on the lines. Manufactured from high-quality carbon steel and typically zinc-plated for enhanced corrosion resistance, the Part 1504 elbow offers a durable and versatile solution for angled connections in hydraulic and pneumatic systems.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Female NPTF Pipe (Dryseal) (threads conforming to ANSI B1.20.3 / SAE J476) |
| End 2 Configuration | Female NPSM Pipe Swivel (National Pipe Straight Mechanical) (threads conforming to ANSI/ASME B1.20.1) |
| Angle | 45 Degrees |
| Body Style | Elbow Adapter with hexagonal (hex) features or flats for secure wrench engagement. |
| Sealing Mechanism | NPTF Female End: Forms a Dryseal (metal-to-metal) when mated with a male NPTF fitting. If connecting to a standard NPT male fitting, the use of a compatible thread sealant on the male NPT threads is required for optimal sealing. NPSM Female Swivel End: NPSM threads are straight and do not seal on the threads themselves. Sealing is typically achieved when this female swivel connects to a male fitting with a tapered seat (e.g., a male NPT or NPTF fitting, where the seal forms on the male tapered threads) or a specific male NPSM fitting designed with a sealing face. The swivel nut facilitates tightening without rotating the elbow body. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Primary Function | To provide a 45-degree connection between two male NPTF (or NPT with sealant) pipes or fittings, with one end featuring a female NPSM swivel for ease of installation and optimal orientation. |
| Working Pressure | Suitable for a range of hydraulic and pneumatic systems. Specific pressure ratings depend on the size of the adapter, the application, and the integrity of the seals on the mating male NPT/NPTF threads. |

Applications
The Part 1504 NPTF Female x NPSM Female Pipe Swivel 45° Elbow is widely used in:
- Connecting two male NPTF (or NPT) pipes or fittings at a 45-degree angle, particularly where the swivel feature on one end aids in orienting one of the connections without disturbing the other, or for connecting to a hose assembly.
- Installations in hydraulic or pneumatic systems where space constraints or fixed component positions make it difficult to rotate standard elbow fittings during assembly, and a 45-degree angle is preferred for routing.
- Adapting fixed male NPTF ports on machinery or equipment to allow for easier connection of a hose or pipe assembly at a 45-degree angle.
- Various industrial piping applications where a robust, steel elbow with a swivel capability is required for NPTF/NPT connections, providing a smoother bend than a 90-degree elbow.
Installation & Usage Guidelines
- Ensure all NPTF female threads, NPSM female swivel threads, and mating male NPTF/NPT threads are meticulously clean, undamaged, and free from any contaminants or debris.
- Thread a mating male NPTF (or NPT with sealant) fitting into the female NPTF end of the Part 1504 elbow. NPTF threads are designed for a Dryseal connection with a male NPTF fitting; however, for optimal sealing, especially if the mating male fitting is standard NPT, the application of a compatible thread sealant (such as PTFE tape or pipe dope) to the male threads is highly recommended. Tighten to the appropriate specification.
- Align the elbow to the desired 45-degree orientation.
- Connect the female NPSM swivel end of the adapter to a second mating male NPT or specific NPSM fitting. The swivel nut allows the elbow body to be held stationary in its oriented position while the nut is tightened independently. Ensure that the sealing mechanism of the mating male fitting (e.g., its own tapered threads for NPT, or a specific seat for certain NPSM males) is correctly engaged. If connecting to a male NPT fitting, ensure thread sealant is applied to the male threads.
- Always use appropriate backup wrenches on the elbow's hex body and the mating components during the tightening process to prevent over-torquing or damage to the fittings.
