The Gentec® 155LX-200 is an extra high-flow liquid oxygen regulator designed for heavy-duty industrial applications requiring large, stable gas delivery. Commonly used with a vaporizer or manifold syetem to run burning bars, multi-torch setups, and the Victor® Bazooka HC1500 cutting torch. This regulator delivers outstanding performance and reliability under continuous, high-demand operation.

Built for maximum flow capacity, the 155LX-200 features a forged brass body and housing cap, a 3-1/4″ stainless steel diaphragm for steady pressure control, and a Delrin® cap bushing for smooth, precise adjustments. The large, 2.5″ easy-to-read outlet gauge allows operators to monitor pressure at a glance, ensuring consistent results in demanding environments.
