Oatey Safe-Flo 29025 Lead-Free Wire Solder 1 lb – Silver Bearing, 0.084 in, 415-455°F

Overview

Oatey Safe-Flo 29025 is a lead-free wire solder designed for copper plumbing and potable water line work. The silver-bearing alloy is formulated to flow smoothly into joints, delivering a reliable seal without the burden of excess heat. The 0.084 inch gauge and the alloy mix help balance strength and ease of use, while the broad melting window gives plumbers more time to align parts and apply solder precisely. Oatey has earned the trust of professionals for more than a century, and Safe-Flo continues that legacy with consistent performance and accessible technical support.
