DELPHI FITTINGS
Part Number: 5700-SS
NPTF Pipe Male x Pipe Swivel Male 90° Elbow (Stainless Steel)
Product Overview
The Delphi Fittings Part 5700-SS is a 90° elbow featuring one standard male NPTF (Dryseal) end and one male NPTF swivel end. This innovative design allows for easy installation and alignment when connecting two female NPTF ports at a right angle. The swivel end can be tightened independently of the fitting's body, preventing the need to rotate the entire elbow to make the final connection. 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, and other harsh environments.

Applications
The Part 5700-SS Stainless Steel Swivel Elbow is ideal for:
- Connecting two female NPTF or NPT ports at a 90-degree angle, especially where one component is fixed and orienting a standard elbow would be difficult.
- Use in marine and offshore hydraulic systems, chemical processing plants, food and beverage facilities, and pharmaceutical production where corrosion resistance is essential.
- Simplifying plumbing in tight spaces by allowing the final connection to be made without rotating the fitting body.
- 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. If mating with standard NPT female ports, a compatible sealant (like PTFE tape) is also required.
- Thread the fixed (non-swivel) male end into the first female port and tighten to the desired orientation.
- Thread the swivel male end into the second female port. The swivel action allows you to tighten this connection with a wrench without turning the already positioned elbow body.
- Use appropriate wrenches on the hex body of the elbow and on the mating components to tighten securely. Avoid over-tightening.
