DELPHI FITTINGS
Part Number: 5405-SS
NPTF Pipe Internal External Connector (Stainless Steel)
Product Overview
The Delphi Fittings Part 5405-SS is a versatile straight adapter, often referred to as an internal/external connector or an extender. This fitting is precision-machined from high-quality stainless steel (typically Grade 316 SS) and usually features a male NPTF (Dryseal) thread on one end and a female NPTF (Dryseal) thread of the same size on the other. It is designed to extend an existing male pipe thread or to adapt a connection in a straight line. The stainless steel construction provides excellent resistance to corrosion, chemicals, and extreme temperatures, making it ideal for demanding applications where standard steel fittings would be unsuitable, such as in marine, chemical processing, food and beverage, or pharmaceutical industries.
Key Features & Specifications
| Material | High-Grade Stainless Steel (Typically 316 SS for superior corrosion resistance) |
|---|---|
| End 1 Configuration | Typically Male NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476) |
| End 2 Configuration | Typically Female NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476) |
| Body Style | Straight Adapter with a hexagonal (hex) body for secure wrench engagement. |
| Sealing Mechanism | Both ends utilize NPTF Dryseal threads, designed to create a metal-to-metal seal when mated with other NPTF fittings. When connecting to standard NPT threads, a compatible thread sealant is highly recommended on the male threads. |

Applications
The Part 5405-SS Stainless Steel Connector is ideal for:
- Extending the reach of a male NPTF pipe or fitting.
- Connecting two components, one with a male NPTF thread and the other with a female NPTF port, in a straight line within a corrosive or high-purity environment.
- Use in marine and offshore hydraulic systems, chemical processing plants, food and beverage facilities, pharmaceutical production, and water treatment systems where corrosion resistance is essential.
- Providing a strong, durable, and leak-resistant in-line connection for stainless steel piping systems.
Installation & Usage Guidelines
- Ensure all mating threads are meticulously clean and free from any damage or contaminants.
- While NPTF threads are designed for a dry seal, it is highly recommended to apply a thread lubricant or anti-galling paste suitable for stainless steel to the male threads of this fitting and the mating male fitting. This will prevent galling and ensure a smooth, secure connection. If mating with standard NPT threads, a compatible sealant (like PTFE tape) is required.
- Thread the female end of the adapter onto the first male NPTF fitting and tighten with a wrench.
- Thread the male end of the adapter into the mating female NPTF port and tighten.
- Use appropriate backup wrenches on the hex body of the adapter and on the mating components to tighten securely and prevent damage.
