Hydraulic steering fittings (such as those found in heavy machinery, marine steering, or high-performance vehicles) are subjected to continuous high, pulsating hydraulic pressure, severe mechanical shock, and high operational temperatures. Any leak compromises steering control, creating an extreme safety hazard. The seal must be absolute and permanent.
This demands a non-negotiable High Strength structural lock.
INCURE ProGrip™ 204 High-Temp Thread Sealant (200°C) for Stainless Steel
The INCURE ProGrip™ 204 Thread Sealant is the superior choice for high-pressure hydraulic applications. Its formulation for extreme heat, high pressure, and challenging metal surfaces provides the permanent, robust seal required for safety-critical steering system fittings.
| Key Feature | Performance for Hydraulic Steering Fittings |
| High Sealing Strength (Permanent) | Creates an absolute, high-pressure seal that resists loosening from severe vibration and immense pressure surges, essential for steering reliability. |
| Extreme Temperature Range | With a range up to 200∘C (392∘F), it safely handles the heat generated by the pump, lines, and hot hydraulic fluid. |
| Best for Passive Metals | Optimized for sealing challenging metals like stainless steel and plated fittings, commonly used in high-pressure hydraulic systems. |
| Max Pressure Rating | Engineered for ultimate pressure resistance (far exceeding typical requirements), crucial for the safety and control of the steering system. |
Application Steps: Sealing Hydraulic Steering Fittings
For maximum safety and permanent reliability, follow these steps:
- Preparation (Critical): Thoroughly clean both the male and female threads to remove all hydraulic 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 port and tighten to the manufacturer’s specified torque.
- Curing (Non-Negotiable): Allow the sealant a full 24 hours to reach maximum strength before introducing hydraulic fluid or operating the steering system.
