The Q Bond Silicone Gasket Maker Grey 85Ml is a high-performance RTV silicone sealant designed to create durable, flexible, and leak-proof gaskets for automotive and mechanical applications. Ideal for sealing engine components, flanges, and joints, this gasket maker replaces traditional materials such as cork, rubber, and paper gaskets. Its strong adhesion and resistance to heat and fluids make it a reliable solution for both DIY repairs and professional maintenance work.

Q Bond Silicone Gasket Maker Grey 85Ml for Leak-Proof Sealing

The Q Bond Silicone Gasket Maker Grey 85Ml is formulated as an RTV (room temperature vulcanising) silicone sealant, offering high strength, flexibility, and excellent adhesion to various surfaces—including oily components.

Once cured, it forms a durable gasket that effectively seals joints and prevents leaks in engines and machinery. It can be used as a direct replacement for traditional gasket materials, providing a more reliable and long-lasting seal.
