[Precision Oxygen Regulator] Designed for welding applications, this regulator features an inlet pressure range of 0-4000 PSI and an adjustable outlet pressure from 0-100 PSI. Equipped with a 9/16inch outlet thread and a 1/4Inch hose connector, it ensures a secure and efficient connection. The CGA540 female nut enhances compatibility with standard oxygen tanks. [Robust Acetylene Regulator] Our acetylene regulator is tailored for torch operations, supporting an inlet pressure up to 400 PSI and an outlet pressure that can be finely tuned up to 30 PSI. The 9/16inch outlet thread and 1/4inch hose connector provide a reliable link to your welding equipment. Note: This model uses a female nut CGA200, not the male nut CGA510. [Dual Regulator Set for Enhanced Performance] This set includes both oxygen and acetylene regulators. Each gauge features a large diaphragm designed to maintain a consistent pressure output, ensuring optimal performance even as cylinder pressure varies. [ and Reliable Construction] Constructed from solid brass, these regulators offer durability and reliability. The material choice ensures that minor fluctuations in gas delivery pressure do not affect the overall performance, making it ideal for precise welding tasks. [User-Friendly Design with Ergonomic Knobs] Designed with the user in mind, our regulators feature ergonomic knobs that make adjusting gas flows smooth and effortless. This user- design aids in achieving precise control during welding operations, enhancing both safety and efficiency.<br><br>Note:The color and style of the sticker are random, and the designation is not accepted.
