Application, Fitting & Dosing

Clean the pipe to remove metal swarf/grease. Apply the flux carefully to the outside of the pipe surface in the area in which the joint is to be made. Only a very thin layer of flux is required. We do not recommend applying this 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. Do not use too much flux. When soldering, Powerflow Flux can be used effectively with both end feed and integral ring solder fittings. It is also appropriate for lead containing or lead free solders. Powerflow wire or Grade 99C wire are recommended.To minimise the likelihood of corrosion difficulties, it is recommended that the system be flushed out with water as soon as possible after completion. This can be aided by using a proprietary cleaner, such as Fernox Cleaner F3/F5/F8.

Powerflow Flux is WRAS approved. It 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 Fluxite Paste flux is recommended.
