ResOne CGA‑540 Oxygen Cylinder Regulator, Adjustable 0–25 LPM, Aluminum/Brass – MR540‑25B

This regulator is designed for use with CGA‑540 oxygen cylinders and provides adjustable flow settings from 0 to 25 LPM using a click‑style dial with preset positions. The durable aluminum/brass construction measures approximately 6.29 × 1.38 inches, offering a compact and reliable solution for controlled oxygen output from standard cylinders. The integrated pressure gauge provides clear visibility of remaining cylinder pressure, and the single‑barb outlet allows easy connection to compatible oxygen tubing. The regulator supports a maximum inlet pressure of 3000 PSI with a 50 PSI outlet, making it suitable for a wide range of cylinder‑based oxygen applications. This model is engineered to meet applicable industry standards, including ISO10524‑1, ASTM G175‑03, and CGA E‑4, ensuring consistent performance and dependable operation in commercial, industrial, and general oxygen‑cylinder environments.

• Easy to Install and Use: This compact regulator attaches to any CGA‑540 cylinder using the 1‑1/8" nut. Adjust the flow rate from 0 to 25 LPM with the click‑style dial, connect oxygen tubing to the single‑barb outlet, and monitor remaining cylinder pressure with the large integrated gauge.
• Click‑Style Precision: Provides preset flow positions at 0, 0.5, 1, 2, 4, 5, 6, 8, 10, 15, 20, and 25 LPM for consistent and repeatable output control.
• Compact Size with High‑Pressure Capability: Measures approximately 6.29 × 1.38 inches and is engineered for standard oxygen‑cylinder pressures with a 3000 PSI maximum inlet and 50 PSI outlet.
• Durable Aluminum/Brass Construction: Built with a brass core and anodized aluminum body for long‑term reliability in demanding environments.
• Built for Industry Standards: Manufactured in accordance with ISO10524‑1, ASTM G175‑03, and CGA E‑4 requirements for oxygen‑regulator performance and safety.
