Bronze Silver Braze
200 WSP/400 WOG available in sizes 1/4" - 5"
150 WSP/250 WOG available in sizes 6" - 12"
Bronze silver braze (or silbraze, sil-brazed) fittings are made of ASTM B61 or B62 bronze and are constructed with a pipe-sized end socket with a precision groove for the silver ring insert. This permits joining without additional silver solder.
The absence of threads means that there is no reduction of strength at the joint and that thin-wall pipe may be used. Flagg Flow FF, Lee Brass, and other large manufacturers have made these fittings.
