The Blue Star 450 Series Oxygen Regulator is a heavy-duty single-stage regulator engineered for precise oxygen pressure control in cutting, welding, heating, and brazing applications. Designed with a standard CGA-540 oxygen cylinder connection, it delivers an adjustable outlet pressure range of 5–125 PSIG, making it ideal for professional fabrication shops, industrial maintenance, and demanding jobsite use.

Manufactured with a forged brass body and housing cap, this regulator provides exceptional durability and dependable long-term performance. Large 2.5-inch gauges offer clear pressure readings, while the stem-type seat mechanism ensures smooth, accurate adjustments. A fabric-reinforced neoprene diaphragm and sintered inlet filter help maintain consistent gas flow and protect internal components from contamination.
