Item Number: H20-5453BS Have a question about this item?

This all-purpose flux paste is self-cleaning for easy cleanup. Use flux when soldering to create stronger soldered joints by preventing oxidation. Metal tends to oxidize at high temperatures which can weaken or prevent the solder from bonding to the metal. Ideal for creating modern copper foil soldered joints, repairing vintage lead joints and other detailed designs.

Made in the USA
