Questions & Answers

Can this be used on spring wire ?

1 Answer | 
Answer This Question

Thank you for your question. No, we would not recommend this product for soldering spring wire. Oatey Safe-Flo Lead-Free Silver Solder is designed primarily for plumbing applications, such as copper pipe and fittings. For spring wire, a solder intended for wire or electrical applications would be the better choice. If you have any questions or concerns, please reach out to us at technical@oatey.com or call 800-321-9532 and select the technical option.

                      Paid for Oatey and receive Harris solder
                      I ordered and paid for Oatey lead free silver bearing solder but was given Harris plumbing solder instead - when I asked customer service to get me what I ordered they came back with another spool of Harris plumbing solder lol SmH - I give up .. only at homedepot where the employees don’t know a thing about the products they sell. I haven’t used it yet but I’d assume it works the same as the Oatey brand .

                        I used the Oatey lead free solder to fix a leak on my hot water copper line. First time soldering and went great. I have plenty left over in case other leaks spring, or have any other soldering projects.

                        Worked Like a Charm!!!
                        Installed a new hose bibb and I was looking for a smaller size of solder. Found this one at my Queen Creek, AZ Home Depot. A gentleman advised me to get this one since a had a small job to accomplish. Got my Bernzomatic torch kit along with this solder wire and installed a new hose bibb in under 10 minutes. I'm starting to like Bernzomatic products...I would recommend this product to anyone doing a small plumbing job...I still have some left for a future plumbing job..sweeeet!!
