The Harris Harris Series 220 Gas Manifold is a high-capacity, industrial-grade gas distribution system engineered for facilities that demand safe, reliable, and uninterrupted gas supply across multiple workstations. Designed for applications involving inert shielding gases, oxygen, and acetylene, the Series 220 manifold delivers precisely regulated gas pressure to MIG/GMAW, TIG/GTAW, and oxy-fuel cutting operations throughout a production environment.
Built to handle demanding throughput requirements in fabrication shops, shipyards, aerospace facilities, and industrial manufacturing plants, the Series 220 manifolds support both standard-pressure and high-pressure configurations. Each unit features robust brass construction, color-coded connections for gas identification, and integrated pressure regulation for consistent downstream delivery — reducing downtime and eliminating the inefficiency of individual cylinder management at each workstation.
