Oatey 15804 Hercules Megaloc is a multipurpose thread sealant for assembling compatible threaded metal and plastic pipe and fittings. The soft-setting formula is designed to seal threaded connections without a cure-time wait, making it useful for plumbing, mechanical and service work where a clean, workable pipe-joint compound is preferred. It is approved for drinking-water lines and can be used across a broad temperature range while resisting hardening and cracking over time.
