A 28/400 pump. Every bottle we make — 16 oz and 32 oz alike — uses a 28/400 neck, so any pump on this page fits any bottle in the range. How do I know whether my own bottle is 28/400? Measure across the threads at the mouth. 28/400 means 28 mm across, with a standard 400-series thread — the most common closure on soap, lotion and Boston round bottles. If it measures 28 mm, this pump fits. What is it made of? 304 stainless steel, chosen to resist rust and wear from repeated contact with soap. Can I change the finish without replacing the bottle? Yes. All ten finishes share the same thread, so a pump is the simplest way to change how a bottle you already own looks. Need the bottle as well? These pumps ship on every bottle we make.
