Our rugged, medium-duty industrial-grade regulators are built for durability, incorporating Smith's exclusive Sure Seat filtered seat technology for prolonged seat and regulator life. This technology prevents contamination from entering the seating area, reducing repair costs and minimizing downtime. Manufactured with a sturdy forged body and corrosion-resistant bright nickel-plated bonnet, Series 30 regulators are made in the USA and come with a 3-year limited warranty.

Designed for economical and compact single-stage gas control, these regulators are ideal for torches requiring low gas flow and outlet pressure. Gas connections are designated as follows: 520 for “B” tank (40 cu. ft.), 200 for "MC" tank (10 cu. ft.), 540 for "Oxygen" (all tank sizes), and 510 for "Large" tanks (60-400 cu. ft.) with internal threads.
