Overview
The Unbranded 85-12XUI-580 dual gauge regulator is a precision pressure control device engineered for professional welding and gas delivery systems. This CGA-580 inlet regulator features dual independent gauges for simultaneous monitoring of cylinder pressure and working output pressure, making it essential for TIG, MIG, and plasma cutting applications. The unit delivers stable, regulated gas flow across a wide range of inert gases including argon, nitrogen, and helium mixtures.
Key Features
- Dual independent pressure gauges for cylinder and output pressure monitoring
- CGA-580 inlet connection—industry standard for inert gas cylinders
- Output pressure range: 0–25 PSI for precise regulation
- Inlet gauge range: 0–4000 PSI for safe cylinder status verification
- Brass body with durable internal seating for long service life
- Tamper-proof, self-reseating relief valve for safety
- Compact design suitable for bench-top and mobile welding setups
