System 48 rod and flux together has the best capillary action and deepest filler penetration of all previous Silver Brazing formulas.

System 48 Also will build connection fillets for seat stays, brake bridges, cantilever bosses, and is the only filler needed to build complete frame sets using lugs.

System 48 Flow temp is same as older 56% silver fillers and flux washes off with water.

• Gap filling is zero to over ten thousands for sure secure joints.

• Security equal to higher temp braze joints.

This combination of alloy and flux was refined over a two-year period through extensive real-world testing. More than one hundred formulas were tried; "System 48" has proven to be superior to any other formulation!

The "Group" agreed this is as good as it gets!
