Customer Reviews for Oatey H-20 1.7 oz. Lead-Free Water Soluble Solder Flux Paste

It's flux. It works. Only issue is that someone used it and returned it so it was half empty

first time go so get the best. solder brought in and held.

Extremely poor container design. Product is more liquid than paste. Container is flimsy thin wall PVC. Long story short. When I finally got it opened, the vapor locked lid went flyingand the base ended upside down on top of my new Water Heater. I be not happy. Oh! Getting the lid back on was interesting also. You have to distort the container to release the air trapped under the lid to get it closed. Solution : Hl Peteeavier wall container with THREADED base and top. The water soluble paste worked well

In store people were very helpful

Use the material it’s pretty self-explanatory. As long as you do the prep work, the solder works just like butter and it will go into the seams when needed to.

Got the job done with no problems. Perfect wire connection with a neat and strong bond.

Great solder flux gets the job done.

Solve the problem and fix the pipes tighten with this

Worked great for me... a very thin, even film on both parts is all that was required. Then you don't have to worry about much flux being in the lines in the first place. That coupled with cleaned fittings and pipe of course, and it's pretty easy to sweat joints.

It works as intended.

Great product and easy to clean up any excess that gets on parts.

Works very well, and washes off my hands easily as it is water soluble.

Too runny, sucks. Would nevwr use again. Threw in trash and got paste
