DELPHI FITTINGS
Part Number: 5504-SS
NPTF Pipe Female 90° Elbow (Stainless Steel)
Product Overview
The Delphi Fittings Part 5504-SS is a 90° female pipe elbow designed to connect two male NPT (National Pipe Taper) or NPTF (Dryseal) threaded pipes 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 female ends are machined to higher tolerances to create a reliable metal-to-metal seal with male NPTF fittings. 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 5504-SS Stainless Steel 90° Female Elbow is ideal for:
- Creating a 90-degree connection between two male NPTF or NPT pipes or fittings 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 cleaning cycles 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 male NPTF threads and the female 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 the male threads of the mating fittings. If mating with standard NPT male threads, a compatible sealant (like PTFE tape) is also required.
- Thread the male fittings into each end of the elbow by hand until snug.
- Use appropriate wrenches on the hex body of the elbow and on the mating fittings to tighten securely. Tighten until a leak-proof seal is achieved, but avoid over-tightening.
