DELPHI FITTINGS
Part Number: 5503
NPTF Pipe 45° Street Elbow
Product Overview
The Delphi Fittings Part 5503 is an NPTF Pipe 45° Street Elbow, also known as a 45-degree street ell or service ell. It is specifically designed to change the direction of flow by 45 degrees while offering a space-saving connection. This fitting uniquely combines one male NPTF (Dryseal) thread on one end and one female NPTF (Dryseal) thread on the other. This allows the male end to connect directly into a female port or another fitting, while the female end can accept a male NPTF pipe or fitting, effectively eliminating the need for an additional nipple for the 45-degree turn. Constructed from high-quality carbon steel, the 5503 street elbow is a durable solution for precise angular routing in various fluid systems.

Applications
The Part 5503 NPTF Pipe 45° Street Elbow is valuable in applications requiring a gentle change in direction and compact assembly:
- Connecting pipes or hoses to components like valves, pumps, or cylinders at a 45-degree angle without an extra nipple.
- Gauge installations where a 45-degree orientation is needed for better visibility or clearance.
- Hydraulic and pneumatic systems in industrial machinery, mobile equipment, and automotive applications where space is a consideration.
- Plumbing and piping installations needing precise angular adjustments.
- Creating smoother flow paths compared to 90-degree turns directly off a port.
Installation & Usage Guidelines
- Inspect all threads: the male end of the street elbow, the mating female port, the internal female threads of the elbow, and the mating male fitting. Ensure they are clean and undamaged.
- Thread the male end of the 45° street elbow into the female port, starting by hand to ensure proper alignment.
- Use an appropriate wrench on the body of the street elbow to tighten it to the desired 45-degree orientation.
- Thread the mating male NPTF fitting into the female end of the street elbow, first by hand, then with a wrench.
- NPTF Dryseal threads are designed for a metal-to-metal seal. If connecting to standard NPT threads, or for very high pressures, consider using a compatible thread sealant or lubricant on the male threads.
- Ensure all connections are tightened securely to achieve a leak-proof seal without over-stressing the fittings.
