Oatey Hercules Multi-Purpose Plastic Seal is a single-component polyurethane sealant designed for demanding plumbing, construction, automotive, RV and marine applications. This durable sealant cures to a firm yet flexible, waterproof and weather-resistant seal that solves common problems in both professional and home repair settings, including sealing soil-pipe joints, caulking frame perimeters, ductwork, expansion joints and glazing applications.
The odorless formula sets rapidly while remaining flexible after curing, making it ideal for joints that experience movement or settling. Its crack-proof, shrink-proof construction means a lasting seal without the worry of failure over time. Manufactured in the United States, this sealant produces no fumes during the curing process, creating a safer working environment.
