Lead-free plumbing solder

Oatey 22004 is a 95/5 tin-antimony wire solder formulated for potable water copper lines. The lead-free alloy meets safety requirements for drinking water systems. Users apply external flux to control exactly where the solder flows during each joint.

Melting range limits

The alloy melts between 450°F and 464°F, so the joint temperature must stay inside that window for proper flow. Overheating can burn the flux and weaken the bond while insufficient heat leaves voids. Consistent torch control is essential for reliable connections.

Vibration-resistant alloy

The 95% tin and 5% antimony composition is chosen for installations that face frequent and extreme temperature changes and vibration. This specific alloy resists fatigue cracking better than softer solders in those conditions. Select a different alloy if the service environment is stable and vibration-free.

Questions about this item

What does the 95/5 ratio mean for my plumbing job?

The alloy is 95% tin and 5% antimony, giving a melting range of 450°F to 464°F. It is lead-free, so it meets requirements for potable water copper lines, and you control flow by applying flux only where you want the solder to run.

How does the 450°F–464°F melting range behave on a real copper joint?

Within that window the solder turns fully liquid, letting capillary action pull it into the fitting. The antimony content adds strength for systems that see frequent temperature swings and vibration, so the joint resists cracking better than softer alloys.

What flux standard should I pair with this wire solder?

The product is designed for use with external flux; you choose the paste or liquid flux rated for lead-free tin-antimony alloys and apply it only where solder flow is wanted. No proprietary flux system is required.
