DELPHI FITTINGS
Part Number: 5500-SS
NPTF Pipe 90° Male Elbow (Stainless Steel)
Product Overview
The Delphi Fittings Part 5500-SS is a 90° male pipe elbow designed to connect two female NPT (National Pipe Taper) or NPTF (Dryseal) threaded ports or fittings at a right angle. Manufactured from premium stainless steel (typically Grade 316 SS), this elbow offers exceptional resistance to corrosion, chemicals, and extreme temperatures. Its NPTF (Dryseal) threads on both male ends are machined to higher tolerances to create a reliable metal-to-metal seal with female NPTF ports. This fitting is an excellent choice for demanding applications in marine, chemical processing, food and beverage, and other harsh environments where a durable, corrosion-resistant 90-degree connection is required.

Applications
The Part 5500-SS Stainless Steel 90° Male Elbow is ideal for:
- Creating a 90-degree connection between two female NPTF or NPT ports in environments where superior corrosion resistance is critical.
- Use in marine and offshore hydraulic systems, chemical processing plants, food and beverage facilities, pharmaceutical production, and water treatment systems.
- Applications involving corrosive fluids, high humidity, saltwater spray, or frequent washdowns where carbon steel fittings would degrade.
- Providing a strong, durable, and leak-resistant right-angle connection for stainless steel piping systems.
Installation & Usage Guidelines
- Ensure all mating female NPTF threads and the male NPTF threads of the elbow 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 both male threads. If mating with standard NPT female ports, a compatible sealant (like PTFE tape) is also required.
- Thread one end of the elbow into the first female port by hand until snug.
- Use appropriate wrenches on the hex body of the elbow and on the mating components to tighten securely. Tighten until the elbow is correctly oriented and a leak-proof seal is achieved, but avoid over-tightening.
