ThreeBond 1215 Gray RTV Silicone Sealant 250g High-Temp Flexible Oil-Resistant Gasket Maker for Engine Flanges and Automotive Maintenance

Main component Silicone Exterior Gray Viscosity 75 Pa·s ThreeBond TB1215 is a gray RTV silicone gasket material formulated as a single component, solvent free sealant designed for engineering use. It is supplied in a 250g tube equipped with a fingertip-controlled nozzle, making it suitable for installation, routine servicing and repair work. This material is commonly chosen not only for general mechanical applications but also in high performance automotive and motorsport environments where reliability is essential. This silicone formulation offers exceptional resistance to oils, lubricants and a wide range of chemicals. It provides strong mechanical durability under shear forces and adheres effectively even on surfaces that may not be perfectly clean. TB1215 also provides a number of additional performance advantages. It cures without shrinking, forms an immediate moisture and fluid barrier, endures pressure conditions, and maintains stability when exposed to high temperatures. Its high resistance to oils and chemicals further enhances its suitability for engine, flange and precision sealing applications.

• Highly resistant to oils and a wide range of chemicals
• Strong bonding performance on metal substrates including aluminum and steel
