Product Description

The UNIWELD Light/Medium Duty Oxygen Regulator A-Conn/CGA540 (SKU RO100, MPN RO100) is a single-stage air and inert gas regulator with a CGA 540 inlet and a 3/8"-24 M RH outlet. It features a Neoprene diaphragm and is rated for 60 psig outlet pressure.

Frequently Asked Questions

What is the UNIWELD RO100 oxygen regulator used for?

The UNIWELD RO100 is a single-stage oxygen regulator used in light to medium duty welding, cutting, and brazing applications. It reduces cylinder pressure to a stable 60 psig outlet for air and inert gas systems. Common in fabrication shops and maintenance facilities.

What are the specifications of the UNIWELD RO100 regulator?

The UNIWELD RO100 has a CGA 540 inlet and a 3/8"-24 M RH outlet. It features a Neoprene diaphragm and delivers a maximum outlet pressure of 60 psig. The single-stage design provides consistent flow for light/medium duty oxygen service.

Where to buy the UNIWELD RO100 regulator worldwide?

3G Electric supplies the UNIWELD RO100 regulator worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this CGA 540 oxygen regulator.

How to install the UNIWELD RO100 oxygen regulator?

Ensure the CGA 540 inlet is clean and free of debris before attaching to the cylinder valve. Tighten the connection with a wrench, then slowly open the cylinder valve while checking for leaks. Adjust outlet pressure to 60 psig using the adjustment knob. Always follow UNIWELD safety guidelines.
