Single-Stage Acetylene Regulator
The Miller-Smith 30-15-300 is a single-stage brass regulator built for general-purpose acetylene use. It delivers a fixed 15 psi outlet pressure through a CGA-300 cylinder connection. The 2-inch gauges show supply pressure up to 400 psi and delivery pressure. A nickel-plated bonnet and Sure Seat filtered seat are included.
Check Cylinder and Hose Compatibility
Verify that your acetylene cylinder carries a CGA-300 valve outlet before ordering. The regulator outlet uses a 9/16 in.-18 LH thread, so confirm your hose or torch fitting matches this connection. Ensure the system design accepts a single-stage delivery characteristic and a maximum inlet pressure of 400 psi.
Brass Body with Filtered Seat
The brass body and neoprene diaphragm handle acetylene service within the rated pressures. The filtered seat helps keep contaminants from the downstream equipment. The 2.0-inch body diameter fits standard regulator mounting arrangements. This unit is UL Listed and has no state sales restrictions.

Questions about this item
What comes in the box with the Miller-Smith Equipment 30-15-300 regulator and what extra parts must be purchased separately?
The regulator includes a bright nickel-plated bonnet and a Sure Seat filtered seat. You will need to buy a CGA-300 cylinder connection, a 9/16 in.-18 LH B outlet hose, and a 2 in. supply-pressure gauge separately.
How do I decide between the 15 psi delivery-pressure range and other available pressure options for this model?
Choose the 15 psi version when your acetylene application requires a low, steady working pressure up to 15 psi; higher-range models are intended for processes that need greater outlet pressure.
What does the 400 psi maximum inlet pressure mean when the regulator is connected to a live acetylene cylinder?
It indicates the regulator can safely handle cylinder pressures up to 400 psi, which covers standard acetylene cylinder pressures encountered in general-purpose welding use.
