OATEY 30041 – Frequently Asked Questions
1) Can Oatey No. 5 paste flux be used on potable water lines?
Yes. Oatey 30041 No. 5 paste flux is 100% lead-free and safe for potable water work. It carries NSF Standard 14 (performance) and NSF Standard 61 (health effects) certification, which is what most inspectors want to see on domestic water piping.
2) Will Oatey No. 5 flux work on stainless steel or aluminum?
No. The No. 5 paste flux works on all metals except aluminum and stainless steel. For copper, brass, and common plumbing metals it is fine, but for stainless or aluminum joints you need a different flux chemistry.
3) Is this flux suitable for large diameter copper pipe soldering?
Yes, that's a stated strength of the Oatey 30041 No. 5 paste flux. The petroleum-base formula holds up on larger copper joints where the pipe takes longer to come up to temperature, cleaning and fluxing the copper for uniform solder flow.
4) Does Oatey No. 5 paste flux work with lead-free solder?
It's compatible with all common plumbing solder alloys, so lead-free 95/5 tin-antimony and tin-silver wire solders are fine with it. The flux itself is also lead-free, so the whole joint stays compliant for potable water.
5) Will this flux stain or turn my copper pipe green?
No. Oatey's No. 5 paste flux is formulated so it will not turn copper piping green, which matters on exposed copper runs where the finished work is visible.
6) What size container is the Oatey 30041 and how much does it weigh?
It's a 16 oz tub of No. 5 paste flux, part number 30041, with a listed product weight of 1.156 lb including the container and brush. The amber-colored paste is the standard No. 5 petroleum-base formula.
