Introduction

Oxygen regulators attach to cylinders and reduce high tank pressure to a safe, adjustable flow rate for respiratory therapy or emergency use.

  • Precision gauges display both cylinder contents and delivered flow settings.
  • Standard outlet ports connect to tubing, masks, or nasal cannulas without adapters.
  • Built-in safety relief valves protect against over-pressurization during operation.

Select the model that matches your tank fitting and prescribed flow range.

FAQs

Check the valve type stamped on the cylinder neck. CGA 870 and CGA 540 are the most common medical and industrial standards.

Medical regulators often range from 0-8 LPM or 0-15 LPM. Confirm the range meets your prescription or equipment requirements.

Most home and clinical models are reusable with proper cleaning between patients. Follow manufacturer disinfection guidelines.

Regulations vary by region. Some areas allow over-the-counter purchase while others require a physician's order.

Standard regulators are designed for compressed gas cylinders. Portable concentrators usually have built-in flow controls instead.
