HTP5 - Smith 30 Series Oxygen & Acetylene Regulator Twin Pack (CGA 540/300)

Upgrade Your Oxy-Fuel Setup with Miller Smith Reliability

For welders who refuse to compromise on flame stability and equipment longevity, the Miller Smith HTP5 Regulator Twin Pack is the smart choice. This convenient bundle outfits your oxy-acetylene rig with two premium 30 Series regulators, renowned in the industry for their "set it and forget it" reliability. Whether you are performing intricate brazing, general welding, or cutting steel, consistent gas flow is the key to a quality result. The HTP5 pack delivers exactly that, minimizing the common issue of "decay/rise" where outlet pressure fluctuates as your cylinder pressure drops. Smith 30 Series regulators are designed to compensate for these changes, saving you gas and frustration.

Built for the Welding Shop

Welding environments are tough on gear. Tools get dropped, banged, and exposed to dust and fumes. The Smith 30 Series is built to take it. The regulators feature a tube-within-a-tube design on compatible handles, but the regulators themselves boast a corrosion-resistant nickel-plated bonnet that stands up to shop abuse better than standard brass alone. The gauges are often the first thing to break on a regulator, but Smith uses shatter-resistant polycarbonate lenses to ensure you can always read your pressures clearly, even after years of service. The color-coded labels—green for oxygen and red for fuel—make identification instant, reducing setup errors.

The CGA 300 Difference

It is critical to check your acetylene cylinder before ordering. The HTP5 pack comes with a CGA 300 acetylene regulator. This connection is designed for acetylene tank valves that have male threads (requiring a female nut on the regulator). This is distinct from the CGA 510 connection often found on other tanks. By choosing the correct connection, you ensure a safe, leak-free seal without the need for dangerous adapters. The Oxygen regulator features the standard CGA 540 connection found on almost all high-pressure oxygen cylinders.

True Blue Warranty

Investing in the HTP5 Twin Pack means investing in American-made quality. These regulators are manufactured in the USA and are backed by Miller's True Blue 3-Year Limited Warranty. This commitment to quality ensures that your investment is protected and that you have the support of one of the biggest names in welding. Don't let cheap, inconsistent regulators ruin your welds or waste your gas—step up to the Smith 30 Series.
