Red High Temp RTV Gasket - Soudal Accumetric

The Soudal Accumetric 49272 Red High Temp RTV Gasket is a professional-grade, single-component silicone gasket maker designed for demanding high-heat and high-load sealing applications in both automotive and industrial environments. This formulation provides technicians with a robust solution for creating durable form-in-place gaskets, ensuring seal integrity on modern equipment subjected to continuous service and extreme conditions.

Key Features

• Extreme Temperature Resistance: Engineered to withstand continuous exposure up to 550°F (287°C) and intermittent spikes to 650°F (343°C), ensuring reliable sealing in critical areas such as late-model gasoline and diesel engines, turbocharger housings, and exhaust systems.
• High-Pressure & Gap Filling Capability: Formulated to maintain integrity under pressures up to 1450 psi (10 MPa) and effectively fill gaps up to 0.25 inches (6.35 mm). This capability aids in restoring sealing effectiveness on worn or imperfect flange surfaces, reducing the need for costly machining.
• Efficient Cure and Durability: Becomes tack-free within 10–20 minutes and achieves a full cure in 24 hours, forming a flexible Shore A ~24 rubber that resists degradation from vibration, thermal cycling, and flange movement.
• Sensor-Safe & Low VOC: A neutral cure formulation ensures compatibility with oxygen sensors in late-model engines and features a low VOC content (<3%), contributing to improved shop air quality.
• Comprehensive Fluid Resistance: Provides long-term sealing performance in powertrain, driveline, and general industrial service by resisting degradation from common automotive fluids, including engine oil, automatic transmission fluid (ATF), gear oil, coolants, and water, while remaining non-corrosive to metals.

Applications

Utilize Soudal Accumetric 49272 for creating form-in-place gaskets on critical automotive components such as oil pans, valve covers, timing covers, water pumps, thermostat housings, transmission and differential covers, and turbochargers. It is also suitable for sealing slip-fit exhaust joints. In industrial settings, it effectively seals gearboxes, pumps, compressors, HVAC components, and general metal assemblies where high temperature and fluid resistance are essential.
