Fernox Powerflow Flux 350G

Powerflow is a white soft paste which is easily applied to joint areas prior to soldering, designed specifically for the soldering of copper plumbing systems and is suitable for use with a range of metals/alloys and contains no zinc chloride

Application and Dosage

Clean the pipe to remove metal swarf/grease. Apply a thin layer of flux carefully to the outside of the pipe surface in the area in which the joint is to be made but not to the inside of the fitting because any excess flux will be pushed into the tube when pushing the two halves of the joint together. When soldering Powerflow Flux can be used effectively with both end feed and integral ring solder fittings and is also appropriate for lead containing or lead free solders
To minimise the likelihood of corrosion difficulties it is recommended that the system be flushed out with water as soon as possible after completion

Powerflow Flux is WRAS approved, passed tests for use in both hot and cold water systems and is listed in the UK Water Fittings and Materials Directory
Powerflow Flux has been successfully used in gas systems for many years. However there are people who prefer not to use a self-cleaning flux in a gas pipe system. If this is a concern, then Fry Fluxite Paste flux is recommended
