Oxygen Regulators: CGA-540 (US standard)

CGA-540 is the standard fitting for the attachment of a compressed gas cylinder to the required regulator or transfer line in the United States.

Regulator Features Include:
Constant lock-up, flowing pressure range and large flow reserve throughout the pressure charge range of the cylinder. Light weight aluminum body with oxygen compatible brass and seat materials in the critical wetted regulating/throttling high-pressure areas.

Wide operating temperature range. -20 to +50 C:
Special flat-wire Wave-Helix spring design complements the gas dynamics and aging characteristics of the inlet seat to provide lock-up to dynamic pressures that are unusually tightly matched for a piston type regulator design throughout its service life.

Our unique ball-and-flat-seat design provides very fast lock-up response times with an oscillation-free high flow factors specifically designed for use with pulse demand systems.

All of our high pressure oxygen regulators are designed and built by Mountain High in the USA.

High pressure and high flow oxygen regulator with CGA-540 connection.

00REG-1092-0XRegulator CGA-540 2-Stage, Axial

CGA-504 2-Stage Axial Regulator 4mm or 6mm.

The dual stage regulator allows the useful pressure of a cylinder
to be spent down to about 10 psi above the regulating pressure.
This will still yield the specified flow rate for the application while
maintaining specified pressure and flow requirements.
