Loctite SI 596 Gasketing Compound – High-Performance Silicone Sealant for Metal & Plastic Flanges | 300 ml

Loctite SI 596 is a premium red RTV silicone gasketing compound specially designed for sealing flexible flanges on metal and plastic components. Engineered to perform under high-stress industrial and automotive conditions, this product provides excellent resistance to heat, oil, and weather, making it ideal for engines, gearboxes, pumps, and flange assemblies.

With its ability to fill gaps of up to 6.35 mm, Loctite SI 596 forms a strong, durable, and flexible seal that prevents leakage and withstands thermal expansion and vibration. It cures at room temperature on exposure to moisture in the air, forming a tough rubber-like seal.

This 300 ml tube is perfect for professional workshops, maintenance operations, and heavy-duty applications, ensuring precision application, high bond strength, and reliable long-term sealing even in high-temperature environments (up to 315°C intermittent).
