EV battery coolant lines are part of a closed-loop thermal management system. They require a sealant strong enough to prevent leaks under medium pressure and vibration, but the system often needs to be disassembled for battery maintenance, repairs, or component replacement. This demands a sealant that provides a secure, leak-proof seal with Medium Strength, allowing for future non-destructive disassembly.
INCURE ProGrip™ 206 Medium Strength Thread Sealant
The INCURE ProGrip™ 206 Thread Sealant is the ideal solution. It is specifically formulated to handle high-pressure applications and features excellent temperature resistance, while maintaining the medium strength bond crucial for serviceable automotive components.
| Key Feature | Performance for EV Battery Coolant Lines |
| Medium Strength (Yellow) | Provides a secure, pressure-tight seal that resists loosening from vehicle vibration but allows for disassembly with standard hand tools for battery service. |
| High Temperature Range | With a temperature range of up to 150∘C (302∘F), it safely handles the operational heat of the battery pack and cooling system. |
| Max Pressure Rating | Seals against high pressures (up to 69 MPa or 10,000 psi), ensuring the lines remain leak-free under dynamic conditions. |
| Low Viscosity | Ensures easy application and penetration into fine or tapered pipe threads, creating a full hydraulic seal. |
Application Steps: Sealing EV Battery Coolant Line Threads
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, grease, 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 pipe or fitting into the housing and tighten to the manufacturer’s specified torque.
- Curing: Allow the sealant to cure for a minimum of 24 hours to reach full chemical resistance and sealing strength before filling the system with coolant or subjecting it to operational pressure and heat.
