250ml Brush Top Hylomar M 8.4oz Can

The 250ml Brush Top Hylomar M 8.4oz Can is a precision sealant compound trusted by tactical professionals, armorers, and military maintenance teams for critical assembly and gasket applications. This industrial-grade product is engineered for environments where reliability is non-negotiable—from weapon systems and optics mounting to hydraulic and pneumatic assemblies. The brush-top applicator design delivers controlled, metered application directly to work surfaces, eliminating waste and ensuring consistent coverage in tight operational spaces.

Hylomar M is a non-setting, anaerobic sealant formulated to cure in the absence of air, creating a chemical-resistant gasket seal that withstands extreme temperature fluctuations and hydraulic pressure cycles common in tactical and military equipment. The formula maintains flexibility after cure, preventing brittle failure under vibration and thermal stress—critical properties for firearms maintenance, vehicle systems, and field-deployable gear. Its low volatility and non-corrosive composition make it safe for use on ferrous metals, alloys, and precision components without degrading finishes or causing material incompatibility issues.

Operators, gunsmiths, and maintenance personnel benefit most from this product when assembling modular weapon platforms, sealing bolt carrier groups, or protecting threaded connections in corrosive environments. The 250ml brush-top can is ideal for field kits and armory workbenches where portability and ease of application matter. Apply directly to gasket surfaces, bolted connections, or threaded joints; allow 24 hours for full cure under standard conditions. Compatible with standard workshop cleaning solvents for easy tool maintenance between applications.
