Hercules 15808 Megaloc Thread Sealant, Kevlar, 16 Oz.

Hercules Megaloc is a premium multi-purpose thread sealant formulated with DuPont™ Kevlar® for sealing pipe threads and fittings on a wide range of materials. Whether you're working with steel, stainless steel, brass, copper, aluminum, or plastics, this versatile sealant delivers a reliable, long-lasting seal that won't fail under pressure or temperature extremes. Plumbers, HVAC technicians, and DIY enthusiasts choose Megaloc to prevent leaks in critical applications where joint integrity matters.

Unlike traditional pipe joint compounds, Hercules Megaloc remains pliable indefinitely—it does not harden, crack, or become brittle over time. This means you can disassemble and reassemble sealed joints years later without damaging the pipe, fittings, or threads. The sealant's grit-free, odor-free formula wipes clean from hands and tools with just a dry rag, reducing mess and cleanup time on every job.
