DELPHI FITTINGS
Part Number: 5406-HP
NPTF Pipe Hex Socket Plug
Product Overview
The Delphi Fittings Part 5406-HP is an NPTF Pipe Hex Socket Plug, specifically designed to provide a secure and reliable seal for unused female NPTF (Dryseal) ports in hydraulic and pneumatic systems. Its key feature is an internal hexagonal (Allen) socket, which allows for a flush or countersunk installation when tightened with a hex key. This low-profile design is ideal for applications where a protruding plug head is undesirable or could interfere with other components. Made from high-quality carbon steel, this plug ensures a durable, leak-proof seal.

Applications
The Part 5406-HP NPTF Pipe Hex Socket Plug is ideal for:
- Sealing off unused ports in hydraulic manifolds, valves, pumps, and cylinders.
- Terminating pipe ends or fittings in pneumatic systems.
- Applications requiring a flush or low-profile seal to avoid interference or for aesthetic reasons.
- Temporary or permanent closure of ports during system testing, maintenance, or modification.
- Use in automotive, industrial machinery, construction equipment, and agricultural implements.
Installation & Usage Guidelines
- Ensure the female NPTF port and the male threads of the plug are clean, dry, and free from any debris or damage.
- Insert the plug into the female port and hand-tighten.
- Use an appropriately sized Allen key (hex wrench) to engage the internal socket and tighten the plug to the recommended torque.
- The NPTF Dryseal threads are designed to seal without the need for additional sealant. However, in some high-pressure applications or if mating with standard NPT threads, a compatible thread sealant or lubricant may be sparingly applied to the male threads to aid sealing and prevent galling.
- Ensure the plug is tightened sufficiently to create a secure seal but avoid over-tightening, which could damage the plug or the port threads.
