Oatey 30014 Lead-Free Solder Paste 8 oz

This lead-free solder paste is formulated for plumbing applications including potable water systems. It suits professional plumbers and DIY users joining copper or brass fittings. The petroleum-based flux meets NSF 14 and NSF 61 standards for safe use. It is not intended for aluminium, magnesium or stainless steel joints.

Sustained heat performance up to 464 °F

The flux remains active at temperatures up to 464 degrees Fahrenheit during extended heating. This stability supports longer soldering sessions on larger diameter pipe without flux burnout. It works with lead-free, leaded, tin/antimony and tin/lead solder alloys. The paste consistency prevents excessive runoff on vertical connections.

Jar packaging simplifies brush application

The 8 oz jar allows direct brush or fingertip application to cleaned fitting surfaces. Users must remove flux residue after soldering with a compatible flux remover. The product cannot be used on aluminium, magnesium or stainless steel materials. No additional installation hardware or specialised tools are required.

Questions about this item

Does the 464 °F maximum active temperature mean the paste produces heavy fumes during long plumbing jobs?

The petroleum-based flux activates up to 464 °F and is formulated for plumbing and potable-water work; use normal ventilation and clean residue with flux remover.

What pipe materials can I join with this No. 5 flux paste?

It works on all metals except aluminium, magnesium and stainless steel, and is approved to NSF 14 and NSF 61 for potable-water systems.

Will this lead-free paste bond reliably to older tin-lead or tin-antimony solder already in the system?

Yes — the paste is rated for lead-free, leaded, tin/antimony and tin/lead solders, so it wets both new and existing joints.
