Soldering copper and brass pipes is inconsistent when using water-soluble flux due to rapid water evaporation, making it hard to get solder to flow properly.

Water-soluble flux evaporates too quickly on larger pipes or brass, reducing soldering reliability; no mention of a purpose-built flux for such applications.

App Concept

FluxPro Stabilize

A non-water-based flux specifically for copper and brass piping that maintains viscosity longer during soldering, ensuring consistent solder flow and stronger joints. Unlike water-soluble variants, it doesn't evaporate rapidly, reducing rework.

Key Features

Oil-based formula resists evaporation on hot pipes
Works on both copper and brass
Thinner included for adjusting consistency
Reduces oxidation and improves solder flow

Target Users: Plumbers and HVAC technicians working with copper and brass piping in residential and commercial settings.

Revenue Model: $12 per 8 oz bottle; bulk pricing for contractors
