DELPHI FITTINGS
Part Number: 5502-SS
NPTF Pipe 90° Street Elbow (Stainless Steel)
Product Overview
The Delphi Fittings Part 5502-SS is a 90° Street Elbow, designed to provide a compact, right-angle connection between a male and a female NPTF (National Pipe Taper Fuel / Dryseal) threaded connection. This fitting features one male NPTF thread and one female NPTF thread, eliminating the need for an additional pipe nipple. Manufactured from premium stainless steel (typically Grade 316 SS), this elbow offers exceptional resistance to corrosion, chemicals, and extreme temperatures, making it an excellent choice for demanding applications in marine, chemical processing, food and beverage, and other harsh environments.

Applications
The Part 5502-SS Stainless Steel 90° Street Elbow is ideal for:
- Creating a compact 90-degree connection between a male pipe/fitting and a female port without needing a separate nipple.
- Use in marine and offshore hydraulic systems, chemical processing plants, food and beverage facilities, pharmaceutical production, and water treatment systems where corrosion resistance is paramount.
- Routing pipes or lines close to walls or equipment, where the space-saving design of a street elbow is beneficial.
- Providing a strong, durable, and leak-resistant right-angle connection for stainless steel piping systems.
Installation & Usage Guidelines
- Ensure all mating threads are meticulously clean and free from any damage or contaminants.
- It is highly recommended to apply a thread lubricant or anti-galling paste suitable for stainless steel to the male threads of this elbow and the mating male fitting. If connecting to standard NPT ports, a compatible sealant (like PTFE tape) is also required.
- Thread the male end of the elbow into the mating female port and orient it to the desired 90-degree direction.
- Thread the mating male fitting into the female end of the elbow.
- Use appropriate wrenches on the hex body of the elbow and on the mating fitting to tighten securely and achieve a leak-proof seal. Avoid over-tightening.
