OATEY 30130 – Frequently Asked Questions
1) Can Oatey H-205 flux be used on copper potable water lines?
Yes. The Oatey 30130 H-205 paste flux is 100% lead-free and certified to NSF standard 14 for performance and standard 61 for health effects, so it is safe on drinking water systems. It also meets ASTM B-813, which is the standard specification most plumbing codes reference for liquid and paste fluxes used on copper tube in potable water piping.
2) Will Oatey H-205 flux work on stainless steel or aluminum?
No. H-205 works on most metals but specifically excludes aluminum and stainless steel. It is formulated for copper tube and common plumbing solder alloys, so for stainless or aluminum joints you need a different flux chemistry entirely.
3) What does water soluble flux mean, and do I still have to clean the joint after soldering?
Water soluble means the residue is water flushable, so after the joint cools you can flush the line and wipe the outside with water instead of scrubbing with a solvent. That matters on potable water systems where leftover acidic residue can sit in the pipe. The 30130 is a water flushable soldering paste flux, and it can be used on copper without discoloring the tube.
4) Is Oatey H-205 the right flux for large diameter copper pipe?
It is built for it. H-205 paste flux is called out for large diameter copper piping, where you need the flux to stay put on a big joint and carry solder uniformly around the full circumference as the heat comes up. The paste cleans and fluxes the copper so the solder flows evenly rather than puddling on one side.
5) What solder do I use with Oatey H-205 flux?
H-205 is compatible with common plumbing solder alloys, which on potable water work means a lead-free wire solder such as a 95/5 tin-antimony or a tin-silver alloy. The flux itself is 100% lead-free, so pairing it with lead-free solder keeps the whole joint compliant for drinking water.
6) How big is the Oatey 30130 flux container, and is that enough for a service truck?
The 30130 is the 1.7 oz size, a small jar for a tool bag or truck stock rather than a full rough-in. Listed product weight is 0.163 and volume 0.005. For a repipe or a day of large diameter work, buy multiples or step up to a larger H-205 container.
