Dutch Boy Silver

Dutch Boy Silver, 1 pound spool, melts at 440° F, with a pasty range of 440° - 640° F. The wide pasty range allows for more working time, making it ideal for working on large (2" and larger) diameter pipe. At 0.4% silver, it has one of the highest silver contents in the industry. Solders with less silver will not provide you with the strength and wide working window necessary for large diameter pipe. Dutch Boy® Silver meets all federal and local specifications for use in potable water systems, including ASTM B-32-2001e1 and ANSI / NSF Standard 61
