DELPHI FITTINGS
Part #: 5655-SS
NPTF Pipe Cross (Stainless Steel)
Product Overview
The Delphi Fittings Part 5655-SS is a high-quality cross fitting designed to create a four-way intersection for pipes or other fittings. This robust component features male NPTF (National Pipe Taper Fuel / Dryseal) threads on all four ports, set at 90-degree angles to each other. Manufactured from premium stainless steel (typically Grade 316 SS), this cross offers exceptional resistance to corrosion, chemicals, and extreme temperatures. Its NPTF (Dryseal) threads are machined to higher tolerances to create a reliable metal-to-metal seal with female NPTF ports, making it an excellent choice for demanding applications in marine, chemical processing, food and beverage, and other harsh environments where a durable, corrosion-resistant four-way junction is required.

Applications
The Part 5655-SS Stainless Steel Male Cross is ideal for:
- Creating a four-way connection point for piping systems in corrosive or high-purity environments.
- Manifold applications where multiple lines need to intersect, or for distributing a single source to three different lines.
- 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.
Installation & Usage Guidelines
- Ensure all mating female NPTF threads and the male NPTF threads of the cross 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 all male threads. If mating with standard NPT female ports, a compatible sealant (like PTFE tape) is also required.
- Thread the ends of the cross into the mating female ports by hand until snug.
- Use appropriate wrenches on the body of the cross and on the mating components to tighten securely. Tighten until a leak-proof seal is achieved, but avoid over-tightening.
