The Fluxuator dual head is an empty, refillable applicator you fill with your own flux paste to brush it onto copper pipe joints before soldering. Per the Amazon listing it has two heads for 15 mm and 22 mm pipe, a click-style dispensing control and a one-handed grip. It suits plumbers and DIYers soldering copper pipe. It is sold empty, so you also need to buy flux.

Who It Is For
- Plumbers and DIYers soldering 15 mm and 22 mm copper pipe and fittings.
- Anyone tired of messy flux tins and brushes.
- Users who want to control how much flux goes onto the joint.
Who Should Skip It
- Buyers who expect flux to be included.
- Anyone working mostly with other pipe sizes or materials.
- Users who only solder a joint or two. A flux brush costs less.
How to Use a Flux Applicator
- Fill the canister with a flux paste that suits copper plumbing. Check the flux label for pipe and drinking-water suitability.
- Clean the pipe end and fitting socket with abrasive cloth or a fitting brush.
- Click out a small amount and coat the pipe end and the inside of the fitting thinly.
- Assemble the joint and solder as normal.
- Wipe off residue once cool and clean the heads so they do not clog.
Too much flux is not better. Excess can run into the pipe, so use only as much as covers the joint surface. For flux types and cleanup see the soldering flux guide.
Care and Refilling
- Wipe flux off the heads with a soft cloth after use.
- Fill only when needed so old paste does not dry out.
- Inspect the heads for wear and replace the applicator if the click or dispensing stops working.
- Keep acidic flux and soldering fumes away from your face and work in a ventilated area.
Pros and Limitations
