Single-stage oxygen regulator
The Miller-Smith Equipment regulator is a single-stage unit built for oxygen service on CGA-540 cylinders. It delivers a working pressure range of 100 psi for general-purpose welding and cutting tasks.
CGA-540 inlet with 100 psi delivery
The inlet connection is CGA-540 rated for a maximum inlet pressure of 3,500 psi, while the outlet uses a 9/16 in.-18 RH B fitting. A 2 in. supply gauge reads up to 4,000 psi so the operator can monitor cylinder contents at a glance.
Brass body with filtered seat
The brass body incorporates a Sure Seat filtered seat and a neoprene diaphragm behind a bright nickel-plated bonnet. The assembly is UL Listed and includes the gauge and bonnet as shown, requiring no extra parts for standard oxygen hookup.

Questions about this item
What does the 100 psi delivery pressure mean when I'm actually welding?
It sets the maximum working pressure at the torch so you can dial the exact flow the job needs without exceeding the regulator's 100 psi limit.
How does the CGA-540 inlet affect which cylinders I can connect?
CGA-540 is the standard oxygen cylinder valve in North America so this regulator threads straight onto any oxygen tank with that outlet.
Will the 9/16-18 RH outlet fit my existing hose and torch fittings?
Yes the 9/16-18 right-hand thread is the common welding hose connection so standard B-size fittings screw on directly.
