Cooling loop threaded connectors (found in engine blocks, server racks, industrial chillers, or geothermal systems) are subjected to medium fluid pressure, temperature variations, and moderate vibration. The primary requirement is a secure, leak-proof seal against coolant. These systems often require periodic draining, flushing, or component replacement(e.g., pumps, radiators).
This demands a sealant that provides a secure, leak-proof seal with Medium Strength, allowing for 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 pressure integrity and temperature resistance while ensuring the joint remains serviceable for maintenance.
| Key Feature | Performance for Cooling Loop Connectors |
| Medium Strength (Yellow) | Provides a secure, pressure-tight seal that resists loosening from pump/flow vibration but still allows for disassembly with standard hand tools for service. |
| High Pressure Rating | Seals against high pressures (up to 69 MPa or 10,000 psi), ensuring the lines remain leak-free under dynamic conditions. |
| Temperature Range | Excellent temperature resistance (up to 150∘C), safely handling the operational heat of most cooling systems. |
| Low Viscosity | Ensures easy application and penetration into threads, creating a complete hydraulic seal against various coolants. |
Application Steps: Sealing Cooling Loop Threaded Connectors
For maximum reliability and a serviceable joint, follow these steps:
- Preparation: Clean both the male and female threads thoroughly to remove all old sealant, oil, and coolant residue. Use an appropriate cleaner (e.g., acetone) and wipe dry.
- Application: Apply a continuous, thin bead of ProGrip™ 206 around the male thread, skipping the first thread. Ensure full coverage over the engaged threads.
- Assembly: Immediately thread the fitting 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 filling the system with coolant or pressurizing the loop.
