Oatey HERPD1PT Hercules Pro Dope Thread Sealant 1 Pint Screw Cap Can with Brush Gray

Product Description

The Oatey HERPD1PT Hercules Pro Dope Thread Sealant is a professional-grade, oil-based pipe thread compound designed for demanding plumbing and mechanical applications. This gray sealant comes in a 1-pint screw cap can with an integrated brush applicator, making it easy to apply a consistent, even coat directly to threaded fittings and pipe joints. The built-in brush eliminates the need for a separate tool and speeds up work on the job site. Plumbers, pipefitters, and mechanical contractors have relied on Pro Dope formulations for decades to create leak-proof threaded connections across a wide range of pipe materials and system types. The oil-based formula delivers excellent lubrication during assembly, helping prevent galling and thread damage on metal fittings. It cures to a firm, durable seal that resists system pressures and temperature swings common in commercial and residential plumbing systems. The composition includes calcium carbonate, petroleum-based lubricating oil, kaolin, and menhaden oil, which work together to fill thread voids and prevent leaks. This sealant is rated for temperatures from 0 to 350 degrees Fahrenheit, covering most hot and cold water, steam, gas, and oil line applications. The flash point exceeds 212 degrees Fahrenheit, and the VOC content is just 11 grams per liter, meeting many low-VOC requirements. Viscosity is rated at 30000 cP, giving the compound a thick, paste-like consistency that stays in place during application and does not run or drip. It bonds to aluminum, black iron, brass, copper, galvanized steel, glass, Monel, and stainless steel, making it one of the most versatile thread sealants available for trade use. HVAC technicians, gas fitters, and industrial maintenance crews will find this compound suitable for a broad range of metallic threaded joint sealing tasks.
