Victor SR260A-300 Acetylene Regulator 2.5 in 15 psig

Victor SR260A-300 Acetylene Regulator

The Victor SR260A-300 is a single-stage, medium-duty gas regulator designed for acetylene applications. It features a 2.5-inch brass body with a neoprene diaphragm and T-handle control for outlet pressure adjustment. The regulator accepts a CGA 300 inlet connection with a 0.825-14 NGO female fitting and provides a 9/16-18 UNF female outlet. It is built for general-purpose welding and cutting tasks requiring reliable pressure control.

Single-stage design for steady low-pressure delivery

This single-stage regulator replaces the need for multi-stage units where constant inlet pressure is maintained or precise downstream stability is not critical. The jump is worth it when the supply cylinder pressure remains relatively stable and the operator needs a compact, straightforward regulator with a maximum outlet of 15 psig. It simplifies setup for medium-duty acetylene work without the complexity or bulk of two-stage alternatives.

15 psig outlet with 3,000 psig gauge capacity

The regulator comfortably handles acetylene supply pressures up to 3,000 psig while delivering a controlled maximum outlet of 15 psig. This headroom suits standard medium-duty welding, brazing, and heating tips. It runs out when the application demands outlet pressures above 15 psig or requires the tighter downstream stability of a two-stage design under rapidly dropping cylinder pressure.
