Miller-Smith HTP5 Regulator for Oxy-Fuel Welding
The Miller-Smith HTP5 is a single-stage gas regulator built for oxy-fuel welding and cutting. It connects directly to high-pressure oxygen and acetylene cylinders using industry-standard fittings. This unit suits professional fabricators and maintenance shops that need reliable gas control for daily torch work.
Single-Stage Delivery Pressure Limits
A single-stage design means outlet pressure rises as cylinder pressure falls during use. The regulator delivers up to 100 psi for oxygen and 15 psi for fuel gas, with inlet ratings of 4000 psi and 400 psi respectively. Operators must re-adjust the torch valves periodically to maintain a steady flame on long jobs.
CGA-540 and CGA-300 Inlet Compatibility
The regulator fits only cylinders equipped with CGA-540 oxygen and CGA-300 acetylene valves. It will not connect to propane, propylene or inert-gas cylinders that use different inlet standards. Buyers using alternative fuel gases or cylinder types must select a different regulator model.

Questions about this item
Should I choose the oxygen or acetylene version of this regulator?
The HTP5 is a single unit with both CGA-540 oxygen and CGA-300 acetylene inlets, so you do not pick one version over the other.
What does the 100 psi oxygen delivery range mean when I am welding?
It lets you set oxygen flow up to 100 psi for cutting or heating, while the fuel side is limited to 15 psi for acetylene safety.
How does the CGA-540 and CGA-300 inlet standard limit what cylinders I can connect?
CGA-540 fits standard oxygen cylinders and CGA-300 fits standard acetylene cylinders; the regulator cannot be used with other gas services.
