DELPHI FITTINGS
Part Number: 5502
NPTF Pipe 90° Street Elbow
Product Overview
The Delphi Fittings Part 5502, an NPTF Pipe 90° Street Elbow (also known as a street ell or service ell), is designed to facilitate a 90-degree change in flow direction while offering versatile connection options. It uniquely features one male NPTF (Dryseal) thread and one female NPTF (Dryseal) thread. This configuration allows the male end to be directly threaded into a female port or fitting, while the female end accepts a male NPTF pipe or fitting. Made from durable carbon steel, the 5502 street elbow is ideal for tight spaces as it eliminates the need for an additional pipe nipple when connecting to a port and making a turn.

Applications
The Part 5502 NPTF Pipe 90° Street Elbow is highly useful in numerous scenarios:
- Connecting a pipe or hose directly to a threaded port on a valve, pump, or cylinder while making a 90-degree turn, saving space and one fitting.
- Gauge installation where a 90-degree orientation is needed close to the port.
- Hydraulic and pneumatic systems in industrial machinery, mobile equipment, and automotive applications.
- Plumbing and piping installations where space is restricted.
- Simplifying connections by reducing the number of fittings required for a directional change at a port.
Installation & Usage Guidelines
- Ensure all threads (male end of the street elbow, mating female port, internal female threads of the elbow, and mating male fitting) are clean and free from damage.
- Thread the male end of the street elbow into the female port, hand-tightening initially.
- Use an appropriate wrench on the body of the street elbow to tighten it into the port, achieving the desired orientation.
- Thread the mating male NPTF fitting into the female end of the street elbow, hand-tightening first, then using a wrench.
- NPTF Dryseal threads are designed to seal without sealant. However, for high pressures or when mating with standard NPT threads, a compatible thread sealant or lubricant can be applied to the male threads.
- Careful tightening is essential to achieve the correct orientation and a leak-proof seal without damaging the fittings.
Why Choose Delphi Fittings Part 5502?
- Space-Saving Design: The male/female configuration eliminates the need for a separate nipple when making a 90-degree turn directly from a port.
- Versatile Connections: Allows for direct connection to components and subsequent connection of other male-threaded fittings.
- Reliable NPTF Sealing: Ensures strong, leak-resistant joints in demanding fluid power applications.
- Durable Carbon Steel: Provides excellent strength and longevity for industrial use.
