Hydraulic steering system flanges (on steering gearboxes, servo valves, and pump assemblies) are non-negotiable points of fluid containment and control. They must hold extreme, continuous system pressure (common in power steering systems), endure constant vibration from vehicle operation, and ensure no fluid loss that could lead to steering drift or failure. A leak in a steering flange is not just fluid loss; it’s a safety hazard that compromises control.
Don’t let pressure loss or fluid leaks threaten the precision and safety of your vehicle’s steering system.
INCURE HeatGrip™ 503 High-Temp Anaerobic Flange Sealant
Steering system components are built with high-tolerance, precision-machined casings that require a seal that is rigid and high-strength to maintain component alignment and pressure integrity. The INCURE HeatGrip™ 503 is engineered for these high-pressure, critical-safety environments, creating a rigid, chemically inert barrier essential for accurate and reliable steering control.
| Feature & Benefit | Technical Insight for Steering Flanges | Conversion Value |
| Superior Pressure Resistance | Cures to a high-strength, rigid plastic that provides maximum resistance to the high internal pressures typical of hydraulic steering systems. | Lock in the Pressure: Achieve an absolute seal that maximizes hydraulic steering force and reliability. |
| High-Temperature Stability | Rated for continuous operation up to 200∘C (392∘F), ensuring the rigid seal remains stable under the friction and thermal load of continuous hydraulic use. | End the Thermal Threat: Get a seal that won’t weaken or degrade, even in the hottest hydraulic fluid loops. |
| Hydraulic Fluid Immunity | Chemically inert to all standard and synthetic power steering and hydraulic fluids, preventing the sealant from breaking down or contaminating the system. | Protect Your System: Ensure the sealant won’t compromise the cleanliness or function of the critical hydraulic fluid. |
| Minimal Gap Sealing | The 503 is ideal for close-tolerance, rigid flanges typical of precision-machined hydraulic components, forming a perfect, gap-free seal. | Precision for Safety: Trust a rigid seal designed to hold integrity in critical, high-pressure, safety-related applications. |
Application Steps: Sealing Hydraulic Steering Flanges for Permanent Integrity
Preparation (Zero Contamination): Thoroughly clean both flange faces—remove all previous sealant, residue, and all traces of hydraulic oil. Use a degreasing solvent (like industrial brake cleaner or acetone) and wipe until the metal surfaces are perfectly dry. Contamination is the enemy of high-pressure anaerobic seals.
Application: Apply a continuous, thin bead of HeatGrip™ 503 onto one flange face, circling all bolt holes. Use a roller or spreader to create a uniform, thin film across the entire mating surface.
Assembly: Immediately mate the two components (within 5 minutes). Torque the bolts to the manufacturer’s specified pattern and value to ensure even clamping and proper anaerobic curing.
Curing Time (Critical): Allow a full 24 hours for the sealant to cure completely. This cure time is mandatory to achieve maximum pressure and thermal resistance before introducing fluid and subjecting the steering system to operational pressure.
Stop risking leaks and maximize your operational control and safety.
