NPTF Pipe Internal External Connector - Part 5405

Part Number: 5405

NPTF Pipe Internal External Connector

Product Overview

The Delphi Fittings Part 5405, an NPTF Pipe Internal External Connector, is a versatile adapter fitting designed for connecting hydraulic or pneumatic components with differing thread requirements. Typically featuring a male NPTF (Dryseal) thread on one end and a female NPTF (Dryseal) thread on the other, this connector allows for seamless integration within complex systems. Manufactured from high-quality carbon steel for strength and durability, and finished with zinc plating for corrosion resistance, the Part 5405 ensures reliable, leak-proof performance in a wide range of industrial applications. Its design facilitates changes in connection gender or adaptation between different NPTF thread sizes.

Key Features & Specifications

Material High-Grade Carbon Steel
Thread Configuration Typically Male NPTF (External) x Female NPTF (Internal). (ANSI B1.20.3, SAE J476)
Body Style Hexagonal body for easy wrench installation and secure tightening.
Sealing Mechanism NPTF Dryseal threads provide a metal-to-metal seal, designed to be effective without additional sealant.
Corrosion Protection Standard Zinc Plating. Other options may be available upon request.
Primary Function Adapts between male and female NPT/NPTF connections; can also be used for changing thread sizes (reducing/expanding).
Working Pressure Suitable for standard hydraulic and pneumatic system pressures. Specific pressure ratings vary by size and application. Please consult our technical data.
Temperature Range Designed for typical operating temperatures in hydraulic systems, actual range depends on fluid media and application specifics.

Applications

The Part 5405 NPTF Internal External Connector is essential in numerous fluid power and piping systems:

  • Connecting components with mismatched thread genders (e.g., male port to male hose end).
  • Adapting port sizes on valves, pumps, cylinders, and manifolds.
  • Hydraulic systems on industrial machinery, construction equipment, and agricultural vehicles.
  • Pneumatic circuits, air compressors, and automated systems.
  • Instrumentation lines and process piping.
  • Maintenance and repair operations requiring versatile connection solutions.
  • General engineering and plumbing applications where NPTF threads are utilized.

Installation & Usage Guidelines

  • Ensure all threads (male external and female internal on the connector, as well as mating component threads) are clean, undamaged, and free of contaminants.
  • Carefully align the connector with the mating parts to prevent cross-threading.
  • Hand-tighten the connector onto the male port and the male fitting into the female port of the connector.
  • Use appropriately sized wrenches on the hexagonal body of the connector and on the mating component to achieve a secure connection. Use a backup wrench where necessary.
  • NPTF Dryseal threads are designed to seal without sealant. However, using a compatible thread lubricant on the male threads can aid assembly, prevent galling, and ensure optimal thread engagement, especially at higher pressures. If mating with standard NPT threads, an appropriate sealant should be used on the NPT male threads.
  • Tighten to recommended torque values, avoiding over-tightening which can distort threads or crack the fittings.
