The Hylomar AF 3.5oz Solvent Free gasket sealer is an essential product for serious automotive technicians and DIY mechanics who demand reliability in critical engine sealing applications. This solvent-free formulation is engineered for use on both metal-to-metal and gasket surfaces where traditional anaerobic sealers or RTV compounds may leave residue or require extended cure times. Whether you're rebuilding a classic engine, servicing a high-performance platform, or performing routine maintenance on fleet vehicles, this compact 3.5oz tube delivers professional-grade sealing without the mess or fumes associated with solvent-based alternatives.
Hylomar AF's solvent-free composition sets it apart by eliminating volatile organic compounds (VOCs) while maintaining exceptional adhesion and gap-filling properties. The formula cures to a flexible, resilient seal that accommodates thermal cycling and vibration without cracking or shrinking—critical for engine block surfaces, transmission pans, timing covers, and valve covers exposed to extreme temperature swings. Its non-hardening nature allows for easy disassembly during future service intervals, preventing the brittle, stuck-joint problems common with rigid sealers. The 0.25 lb compact packaging makes it ideal for shop benches and mobile service kits, with the 3.5oz size sufficient for multiple gasket applications or as a reliable backup supply.
Professional mechanics and restoration shops choose Hylomar AF for precision engine work where contamination control and repeatability matter most. It performs exceptionally well on cast iron, aluminum, and steel surfaces—the core materials of modern and vintage engine architecture—and is compatible with all common gasket materials including cork, rubber, and synthetic compounds. Application is straightforward: apply a thin bead to gasket surfaces, bolt down securely, and allow cure time per manufacturer guidelines before returning the engine to service. This product is particularly valued in shops handling multiple vehicle platforms, from light-duty trucks to performance builds, where a single, proven sealant eliminates the need for shelf space dedicated to brand-specific formulations.
