Applications
The Part 5406-P NPTF Pipe Hex Head Plug is a versatile solution for numerous applications:
- Terminating open female NPTF ports in hydraulic manifolds, valves, pumps, and fluid reservoirs.
- Sealing unused connections in pneumatic systems and air lines.
- Industrial machinery and equipment requiring port closures.
- Automotive and heavy equipment fluid systems.
- Plumbing and piping applications where a secure NPTF seal is needed.
- Temporary or permanent capping of ports during system assembly, maintenance, or pressure testing.
Installation & Usage Guidelines
- Ensure the female NPTF port and the male threads of the hex head plug are clean, dry, and free from contaminants or damage.
- Hand-thread the plug into the female port to ensure proper alignment and avoid cross-threading.
- Use a correctly sized wrench on the external hex head to tighten the plug to the desired torque.
- NPTF Dryseal threads are designed to create a seal without thread sealant. However, for very high pressures or when mating with standard NPT female threads, a compatible thread sealant or lubricant may be applied sparingly to the male threads to enhance sealing and prevent galling.
- Tighten sufficiently to achieve a leak-proof seal but avoid over-tightening, which could damage the plug or the port.
