Oatey HERLUBEOIL Hercules Duck Butter Pipe Joint Lubricant Paste 8 Lb Off-white

Product Description

The Oatey HERLUBEOIL Hercules Duck Butter is a professional-grade pipe joint lubricant formulated for use across a wide range of plumbing and mechanical applications. Supplied in paste form, this product is engineered to reduce friction and ease the assembly of pipe joints, fittings, and couplings. Plumbers, pipefitters, and mechanical contractors rely on paste lubricants like this one to protect threads, prevent galling, and ensure smooth, leak-free connections on both new installations and maintenance work. The off-white paste consistency allows for clean, controlled application directly to pipe threads and joint surfaces without the mess associated with thinner or liquid-based lubricants. The active composition is 15 to 25% mixed sodium and potassium salts of tall oil, a proven lubricating compound widely used in the plumbing trade. This formulation delivers effective lubrication without compromising joint integrity. The product carries a pH of 9, indicating a mildly alkaline profile that helps resist corrosion on metal pipe surfaces. With a flash point above 220 degrees Fahrenheit, this lubricant is safe to handle and store under normal job site conditions. It performs reliably across a temperature range of 10 to 120 degrees Fahrenheit, making it suitable for a broad range of indoor and outdoor plumbing environments. The VOC content is rated at 12 grams per liter, keeping it compliant with many low-VOC regulations. At 8 pounds net weight, this is a substantial container sized for commercial use, service fleets, and high-volume plumbing contractors. The slight odor makes it practical for use in occupied or enclosed spaces. Pipe joint lubricant, also called pipe dope or thread lubricant, is a staple product for every professional plumber handling threaded pipe assemblies.
