The 50/50 Solder is a trusted solution for plumbing, HVAC, and pool equipment repairs where potable water safety is not a concern. This lead-based solder features a 50/50 alloy blend of tin and lead, offering excellent flow characteristics and a consistent melting range. It's widely used for copper DWV systems, tin-plated joints, and maintenance tasks in spa and pool systems. Each bar weighs 1 lb, and it requires a flux for optimal bonding performance.
