DELPHI FITTINGS
Part Number: 1404
NPT Pipe Male x NPSM Female Pipe Swivel
Product Overview
The Delphi Fittings Part 1404 is a straight adapter expertly designed to connect a male NPT (National Pipe Taper) threaded fitting or pipe to a component or hose assembly featuring a female NPSM (National Pipe Straight Mechanical) swivel end. This adapter incorporates a male NPT thread on one end, which forms a seal on the threads through interference fit (requiring the use of a suitable thread sealant), and a female NPSM pipe swivel on the other end. The critical feature of the NPSM swivel nut is that it allows for easy alignment and tightening of the connection without imparting any twist or torsional stress onto the mating hose or component, which is particularly beneficial for preventing damage and ensuring proper installation. Manufactured from high-quality carbon steel and typically zinc-plated for enhanced corrosion resistance, the Part 1404 adapter provides a durable and reliable transition between these two common pipe thread standards.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Male NPT (National Pipe Taper) (threads conforming to ANSI/ASME B1.20.1) |
| End 2 Configuration | Female NPSM Pipe Swivel (National Pipe Straight Mechanical) (threads conforming to ANSI/ASME B1.20.1) |
| Body Style | Straight Adapter with hexagonal (hex) features for secure wrench engagement. |
| Sealing Mechanism | NPT Male End: Achieves a seal on the tapered threads when engaged with a mating female NPT or NPTF port. The use of a thread sealant (e.g., PTFE tape or pipe dope) is required to ensure a leak-proof connection. NPSM Female Swivel End: NPSM threads are straight and do not provide a 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 standard male NPT or NPTF fitting, where the seal forms on the male tapered threads) or, in some cases, a specific male NPSM fitting designed with a sealing face or requiring a gasket (though the former is more common for this type of adapter). The swivel nut allows for tightening without rotating the adapter body. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to corrosion. |
| Primary Function | To provide a straight, reliable connection from a male NPT fitting or pipe to a female NPSM swivel end, facilitating easy installation and correct orientation of the connected line or component. |
| Working Pressure | Suitable for a range of hydraulic and pneumatic systems. Specific pressure ratings are dependent on the size of the adapter, the application, and the integrity of the NPT seal. |

Applications
The Part 1404 NPT Male x NPSM Female Pipe Swivel adapter is widely used in:
- Connecting components with male NPT threads (such as outlets on pumps, valves, filters, or manifolds) to hydraulic hoses or assemblies that are terminated with female NPSM swivel ends.
- Installations where the ability to orient the connected hose or component easily, without imparting twist, is crucial for preventing stress, kinking, or potential damage to the assembly.
- Various hydraulic, pneumatic, and general industrial piping applications where a reliable transition between NPT and NPSM connections is needed along with swivel functionality.
- Facilitating easier and more efficient plumbing in systems where precise alignment of components is required during assembly.
Installation & Usage Guidelines
- Ensure all NPT male threads and NPSM female swivel threads, as well as any mating sealing surfaces (like the seat in the NPSM swivel if applicable, or the female NPT port), are meticulously clean, undamaged, and free from any contaminants or debris.
- Apply a suitable thread sealant (such as PTFE tape or a compatible pipe dope) to the male NPT threads of the Part 1404 adapter. Ensure sealant is applied correctly, avoiding the first one or two threads to prevent system contamination. Do not apply sealant to the NPSM female threads.
- Thread the male NPT end of the adapter into the mating female NPT or NPTF port. Tighten with a wrench to the appropriate specification to achieve a secure, leak-proof seal on the tapered threads. The amount of tightening will depend on the size and materials involved.
- Connect the female NPSM swivel end of the adapter to a mating male NPT or specific NPSM fitting. The swivel nut allows the adapter body to be held stationary (or the connected hose/component to remain untwisted) while the nut is tightened. Ensure that the mating male fitting's sealing mechanism (e.g., its own tapered threads for NPT, or a specific seat for certain NPSM males) is correctly engaged to form the seal.
- Use appropriate backup wrenches on the adapter's hex body and the mating components during tightening to prevent over-torquing or damage to the fittings or connected lines.
Why Choose Delphi Fittings Part 1404?
- Versatile Inter-Standard Connection: Effectively adapts male NPT connections to female NPSM swivel connections, bridging two common pipe thread standards.
- Simplified and Stress-Free Installation: The NPSM female swivel end allows for easy alignment and tightening without imparting torsional stress on the connected hose or component, preventing potential damage and leaks.
- Reliable NPT Sealing: The NPT male end provides a proven tapered thread seal when used correctly with an appropriate thread sealant, ensuring a leak-tight connection on that side.
- Durable Carbon Steel Construction: Manufactured from high-grade carbon steel for excellent strength and longevity in typical hydraulic and pneumatic system environments.
- Enhanced Corrosion Resistance: Standard zinc plating provides robust protection against rust and other environmental corrosive factors, extending the service life of the adapter.
- Adherence to Industry Standards: Both NPT and NPSM threads conform to ANSI/ASME B1.20.1 specifications, ensuring compatibility with other standard-compliant fittings.
- Quality-Assured Manufacturing: Produced under Delphi Fittings' rigorous ISO 9001:2015 certified quality management system.
