Applications
Gas pressure regulators are standard equipment in laboratory gas distribution systems, vacuum chamber setups, compressed gas cylinder stations, and industrial process lines. They are used to reduce high-pressure cylinder gas (nitrogen, argon, CO2, compressed air, and specialty gases) to a controlled working pressure for analytical instruments, vacuum systems, gas chromatographs, welding setups, and general lab bench supply. Vacuum regulators like the Welco unit in this lot are commonly used in vacuum line control for filtration, distillation, and vacuum chamber applications. Standalone pressure gauges and needle valves serve as monitoring and flow-control components throughout these same systems. A mixed lot like this is well suited for a research lab, fab facility, or industrial shop that regularly maintains or builds out gas distribution infrastructure and needs a supply of spare or replacement components on hand.
This lot of gas pressure regulators, valves, and gauges consists of approximately 20+ mixed pieces pulled from a working lab or industrial environment. Items include dual-gauge pressure regulators, vacuum regulators, inline valves, and standalone pressure gauges in chrome, brass, and stainless steel construction. The lot includes identifiable Welco-branded pieces (visible in photos), including a 0–200 PSI gauge and a vacuum regulator. Pieces show typical used wear consistent with lab or gas-line service — light surface oxidation, scuffs, and general handling marks on various items. No hoses or mounting hardware are included. Please view our full photo set carefully to assess the individual pieces, and contact us if you have any questions.
