  • Product typeWelding Supplies
  • Single-stage design simplifies oxygen flow control for welding tasks
  • CGA 540 inlet fits standard high-pressure oxygen cylinders securely
  • Brass body and diaphragm resist corrosion under heavy-duty use
  • 3,000 psig maximum outlet pressure supports demanding applications
  • T-handle adjustment enables precise pressure regulation without tools

Oxygen Regulator for High-Pressure Welding

The Victor Thermal Dynamics 0781-1445 is a single-stage oxygen regulator built for heavy-duty applications. It connects to a CGA 540 cylinder valve using a male 0.908"-14 NGO inlet and delivers gas through a female 1/4 inch Swagelok outlet. A brass body and brass diaphragm handle maximum inlet pressures of 4,000 psig with a maximum outlet pressure of 3,000 psig controlled by a T-handle.

Suited for Industrial Oxygen Control

This regulator suits welders and technicians who need reliable high-pressure oxygen regulation from a standard CGA 540 supply. It is not for users requiring multi-stage pressure stability for precision cutting or applications needing a different outlet fitting such as a hose barb. Buyers needing compatibility with fuel gases or other cylinder valve types should look at alternative models.

T-Handle and Swagelok Outlet Included

The T-handle control allows direct manual adjustment of outlet pressure without extra tools. The female 1/4 inch Swagelok outlet provides a secure, leak-tight connection for compatible tubing. No additional gauges, hoses or adapters are bundled with this unit.

Questions about this item

What CGA-540 oxygen cylinder thread do I need on my tank for this regulator to attach?

The regulator has a male 0.908"-14 NGO inlet that matches a standard CGA-540 oxygen cylinder valve.

Can I keep using my existing 1/4-inch Swagelok hose and fittings with the outlet on this unit?

Yes, the outlet is a female 1/4-inch Swagelok connection compatible with those fittings.

After installation, how do I confirm the regulator is delivering pressure within its rated range?

Watch the outlet gauge; it should read up to 3,000 psig maximum when the T-handle is adjusted.
