Why do brass plumbing fittings pay differently than brass rod or bar stock?
Short answer: Brass rod and bar stock is a known, consistent alloy with no attachments or contamination, while plumbing fittings can include rubber washers, steel fittings threaded on, and mixed alloy grades from different manufacturers — all of which reduce the effective brass content a buyer is actually paying for.

Bar and rod stock comes from a single mill run of a defined alloy, so a buyer knows exactly what they’re getting and can price it against a specific published grade. Plumbing fittings accumulated from multiple jobs or a demolition are a grab-bag of different brass alloys, ages, and conditions.
What actually gets deducted
Rubber O-rings, washers, and gaskets still attached; steel supply lines or fittings threaded onto brass valves; and corrosion or mineral buildup from water service are all common contamination on plumbing brass that rod stock simply doesn’t have.
What improves the price
Pulling obvious rubber and steel attachments before selling, even roughly, moves plumbing fittings closer to a clean brass rate. It won’t fully close the gap to virgin rod stock, but it avoids the steepest “dirty mixed brass” discount.
How ScrapTrade Makes This Easier
Noting “fittings, mostly clean” versus “fittings with attachments” in a ScrapTrade listing lets buyers price the actual condition rather than assuming the worst-case mixed-contamination scenario.
