SKU CH-PMV0-EE0YN

Single-stage flowmeter delivers argon, CO₂ or helium at 50 psi through 5/8"-18 RH connections with a shatter-resistant tube

  • Product typeWelding Supplies
  • Single-stage design simplifies gas regulation for general welding tasks
  • Brass body construction provides durable corrosion resistance in workshop environments
  • Shatter-resistant polycarbonate tube protects flow visibility during daily use
  • Self-centering ball ensures consistent flow readings across Argon, CO2 and Helium
  • 50 psi delivery pressure matches standard cylinder supply requirements

Purpose and fit

The Miller-Smith Equipment H2231A is a single-stage flowmeter built for general-purpose welding with argon, carbon dioxide or helium. It accepts a 5/8"-18 RH external cylinder connection and delivers gas at a fixed 50 psi outlet pressure through a matching internal fitting. The brass body and shatter-resistant polycarbonate tube suit workshop environments where consistent shielding gas flow is required.

Who it suits and who it does not

Welders who need a simple, preset 50 psi regulator for standard MIG or TIG shielding gases will find this unit straightforward to install and operate. Buyers who require adjustable delivery pressure, multi-stage regulation or compatibility with gas types not listed should look at other regulator designs.

What the bundled features change

The self-centering ball seats automatically to help maintain a stable seal on the cylinder valve, reducing setup time. The polycarbonate resin flow tube resists impact damage that can crack glass tubes, keeping the flow reading visible in busy fabrication areas.

Questions about this item

Does this flowmeter need a specific cylinder valve to connect?

It threads directly onto a 5/8"-18 RH external cylinder valve.

Can I keep using my existing 5/8"-18 RH internal hose fitting?

Yes, the outlet accepts the same 5/8"-18 RH internal connection.

How do I confirm the 50 psi delivery pressure is active?

Watch the self-centering ball rise in the shatter-resistant tube when gas flows.
