The Blue Star 250 Series Oxygen Regulator is a dependable single-stage regulator designed to provide accurate oxygen pressure control for welding, cutting, brazing, and heating applications. Featuring a standard CGA-540 oxygen cylinder connection, this regulator delivers an adjustable outlet pressure range of 10–125 PSIG, making it ideal for home users, fabrication shops, repair facilities, and light industrial environments.

Constructed with a durable forged brass body and housing cap, the regulator is built for reliable long-term performance. Large 2-inch gauges provide clear pressure readings, while the stem-type seat mechanism ensures smooth, precise pressure adjustment. A fabric-reinforced neoprene diaphragm, sintered inlet filter, and built-in pressure relief valve help maximize durability and safe operation.
