This is a no-nonsense, medium-duty acetylene regulator built for pros or serious DIYers who need reliable gas control. The main body and housing cap are made from forged brass, which is tough and built to last. It's got a standard CGA510 male inlet connection, which is what you need for most acetylene tanks. It can handle incoming tank pressures up to 400 PSI and lets you dial down and control the working outlet pressure anywhere from 0 up to 30 PSI. The gauges are clear and easy to read. It's a straightforward, industrial-grade piece of equipment. If you're doing welding, cutting, or brazing work and need to precisely manage your acetylene flow, this regulator will do the job reliably. Just make sure you know what you're doing when hooking up gas equipment – safety first!
