OATEY 30372 – Frequently Asked Questions
1) Can Oatey No. 95 tinning flux be used on potable water lines?
Yes. Oatey No. 95 is a 100% lead-free paste flux and is stated as safe for use in drinking water applications, so it suits potable copper water piping as well as fire sprinkler, heating and HVAC systems.
2) What is the difference between a tinning flux and a regular soldering paste flux?
A tinning flux carries added tinning powder that pre-tins the pipe surface as it heats, on top of the normal cleaning and fluxing job. Oatey No. 95 cleans, fluxes and pre-tins copper in one step, which is why it is called out for large diameter copper where getting solder to wet all the way around the joint is harder. If you are soldering small 1/2 inch residential lines, a plain paste flux is usually enough.
3) Will Oatey No. 95 flux work with lead-free solder?
It is compatible with common plumbing solder alloys, which covers the lead-free tin/antimony and tin/silver wire used on potable water work. The flux itself is lead-free paste.
4) Is this flux suitable for fire sprinkler and HVAC copper work, or just plumbing?
Both. Oatey No. 95 is rated for plumbing, fire sprinkler, heating, venting and air conditioning systems. The pre-tinning action and wetting characteristics are the reason it gets specified on the larger-diameter copper mains those trades run.
5) Does Oatey No. 95 flux stain or discolor copper and brass?
No. The No. 95 paste is formulated for use on copper piping and other metals without discoloration. It is a petroleum-base paste, gray in color, and stays smooth rather than running off the joint when the pipe warms up.
6) How much flux is in the Oatey 30372 can?
The 30372 is the 8 oz size, listed at 0.55 lb product weight and 0.017 in volume. For a service truck doing a mix of repair and rough-in it is the common go-to can size; larger tinning jobs are where crews step up to a bigger container.
