Pneumatic system metal flanges (on actuators, valve bodies, reservoirs, or piping) are seals for a critical utility. They must contain pressurized air or gas, often at high pressure, while enduring constant operational pressure and engine or machine vibration. A leak in a pneumatic flange is a direct loss of system efficiency, resulting in wasted energy, reduced tool power, and increased compressor run time.
Don’t let inefficient sealing methods compromise the performance and energy costs of your air system.
INCURE HeatGrip™ 503 High-Temp Anaerobic Flange Sealant
Pneumatic components are generally built with rigid, precision-machined metal flanges (steel, cast iron, or thick aluminum) that require a seal to maintain dimensional integrity and absolute pressure containment. The INCURE HeatGrip™ 503 is engineered for these high-pressure, rigid environments, creating a permanent, high-strength barrier that ensures zero porosity against pressurized air.
| Feature & Benefit | Technical Insight for Pneumatic Flanges | Conversion Value |
| Superior Pressure Resistance | Cures to a high-strength, rigid plastic that provides maximum resistance to high internal air pressure and external sheer forces. | Lock in the Pressure: Achieve an absolute, high-integrity seal that maximizes pneumatic system efficiency. |
| High-Temperature Stability | Rated for continuous operation up to 200∘C (392∘F), ensuring the rigid seal remains stable despite the thermal load from hot compressed air. | End the Thermal Threat: Get a seal that won’t degrade under maximum operational heat. |
| Oil & Gas Immunity | Chemically inert to compressed air, trace lubricants, and other process gases, preventing the degradation of the seal material. | Protect the System: Ensure the sealant won’t break down or contaminate the vital air supply. |
| Minimal Gap Sealing | The 503 is ideal for close-tolerance, rigid flanges typical of precision-machined pneumatic components, forming a perfect, gap-free seal. | Precision for Performance: Trust a seal designed for the tight tolerances of high-pressure air systems. |
Application Steps: Sealing Pneumatic Flanges for Permanent Integrity
Preparation (Critical Cleaning): Thoroughly clean both flange faces—remove all previous gasket material, residue, and any traces of oil or moisture. Use a degreasing solvent (like acetone or brake cleaner) and wipe until the metal surfaces are perfectly dry and spotless.
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 (Mandatory): Allow a full 24 hours for the sealant to cure completely. This time is mandatory to achieve maximum pressure and thermal resistance before introducing air or subjecting the pneumatic system to operational pressure.
Stop risking leaks and maximize your energy efficiency and pneumatic tool performance.
