ASTM B306 Copper Tubes for Drain, Waste and Vent - Dimensions and Working Pressures

Dimensions and specifications of copper tubes ASTM B306 for Drain, Waste and Vent (DWV) applications. DWV pipes are recommended for above ground use only, no pressure applications, and sweat fittings only. This tool provides detailed dimensions and maximum working pressures for both annealed and drawn copper tubes.
