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.
