Power steering fluid line threads are subjected to continuous high, pulsating hydraulic pressure, severe engine vibration, and high temperatures. Any leak can lead to a loss of steering assist and is considered a critical safety issue. The seal must be absolute and permanent. This demands a non-negotiable High Strength structural lock with excellent chemical resistance to hydraulic fluid.
INCURE ProGrip™ 204 High-Temp Thread Sealant (200°C) for Stainless Steel
While the system uses hydraulic fluid, the extremely high pressures, high temperatures, and the need for a non-serviceable, permanent seal make the high-performance INCURE ProGrip™ 204 the optimal choice for maximum safety and reliability.
| Key Feature | Performance for Power Steering Fluid Lines |
| High Sealing Strength (Permanent) | Creates an absolute, high-pressure seal that resists loosening from engine vibration and massive pressure surges within the steering pump and rack. |
| Extreme Temperature Range | With a temperature range up to 200∘C (392∘F), it safely handles the heat generated in the engine compartment and by fluid friction. |
| Best for Passive Metals | Optimized for sealing challenging metals like stainless steel and plated fittings, often used in high-pressure steering systems. |
| Max Pressure Rating | Engineered for ultimate pressure resistance, crucial for the highly stressed hydraulic circuits. |
Application Steps: Sealing Power Steering Fluid Line Threads
For maximum safety and permanent reliability, follow these steps:
- Preparation (Critical): Thoroughly clean both the male and female threads to remove all power steering fluid, oil, and residue. Use an industrial cleaner (e.g., acetone) and wipe dry.
- Application: Apply a continuous bead of ProGrip™ 204 around the male thread, skipping the first thread. Ensure full coverage over the engaged threads.
- Assembly: Immediately thread the fitting into the pump/reservoir/rack and tighten to the manufacturer’s specified torque.
- Curing (Non-Negotiable): Allow the sealant a full 24 hours to reach maximum strength before introducing fluid or operating the system.
