Instrumentation port plugs (used to cap ports for pressure gauges, temperature sensors, or test probes) require an airtight and leak-proof seal under system pressure and vibration. However, these ports are frequently accessed for calibration, testing, or maintenance, demanding a sealant that provides a secure bond while allowing for Medium Strength, non-destructive disassembly.
INCURE ProGrip™ 206 Medium Strength Thread Sealant
The INCURE ProGrip™ 206 Thread Sealant is the ideal solution. It is specifically formulated for high-pressure pipes, providing the necessary strength for pressurized systems while ensuring the joint remains serviceable for access.
| Key Feature | Performance for Instrumentation Port Plugs |
| Medium Strength (Yellow) | Provides a secure, pressure-tight seal that prevents loosening from vibration but still allows for disassembly with standard hand tools for access/calibration. |
| High Pressure Rating | Seals against high pressures (up to 69 MPa or 10,000 psi), ensuring the plug holds fast under system operation. |
| Temperature Range | Excellent temperature resistance (up to 150∘C), suitable for most process and industrial environments. |
| Low Viscosity | Ensures easy application and penetration into fine or tapered pipe threads, creating a complete seal. |
Application Steps: Sealing Instrumentation Port Plugs
For maximum reliability and a serviceable joint, follow these steps:
- Preparation: Clean both the male plug threads and the port threads thoroughly to remove all old sealant, oil, or fluid residue. Use an appropriate cleaner (e.g., acetone) and wipe dry.
- Application: Apply a continuous, thin bead of ProGrip™ 206 around the male thread of the plug, skipping the first thread. Ensure full coverage over the engaged threads.
- Assembly: Immediately thread the plug into the port and tighten to the manufacturer’s specified torque.
- Curing: Allow the sealant to cure for a minimum of 24 hours to reach full strength before pressurizing the system.
