CGA-540 Regulators

• Easy to Install and Use: This compact oxygen cylinder regulator attaches to any CGA‑540 cylinder using the 1‑1/8" nut. Adjust the flow rate from 0 to 15 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, 1.5, 2, 3, 4, 5, 6, 8, 10, and 15 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 to Industry Standards: Manufactured in accordance with ISO10524‑1, ASTM G175‑03, and CGA E‑4 requirements for oxygen cylinder regulator performance and safety.

This mechanical pressure-reduction device is a passive regulator accessory designed for use with pre-filled oxygen cylinders with CGA-540 valves. It provides adjustable flow settings from 0 to 15 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 flow 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 reliable operation in commercial, industrial, and general oxygen‑cylinder environments.
