Pressure transducer fittings must be sealed securely to prevent leaks under system pressure and resist vibration, ensuring accurate readings. However, transducers are expensive instruments that frequently need to be removed for calibration, testing, or replacement. This requires 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 applications, providing the necessary pressure integrity while ensuring the joint remains easily serviceable for instrument access.
| Key Feature | Performance for Pressure Transducer Fittings |
| Medium Strength (Yellow) | Provides a secure, pressure-tight seal that prevents loosening from vibration but still allows for disassembly with standard hand tools for calibration or replacement. |
| High Pressure Rating | Seals against high pressures (up to 69 MPa or 10,000 psi), ensuring the seal holds fast under the system’s operational parameters. |
| Temperature Range | Excellent temperature resistance (up to 150∘C), suitable for most industrial and process environments. |
| Low Viscosity | Ensures easy application and penetration into fine instrument threads, creating a complete seal without clogging the sensor port. |
Application Steps: Sealing Pressure Transducer Fittings
For maximum reliability and a serviceable joint, follow these steps:
- Preparation: Clean both the male transducer 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 transducer, skipping the first thread. Ensure full coverage over the engaged threads.
- Assembly: Immediately thread the transducer into the port and tighten carefully to the manufacturer’s specified torque (avoid overtightening transducers).
- Curing: Allow the sealant to cure for a minimum of 24 hours to reach full strength before pressurizing the system.
