Welding Industrial Hoses | Parker | SIAMEEZ® Grade RM Twin Line Welding Hose | 7110 Series


Series 7110 is a twin line welding hose featuring a flame resistant and oil resistant cover. The red line is compatible ONLY with acetylene fuel gas, and the green line is compatible with oxygen. The non-blooming tube minimizes the migration of combustible waxes or plasticizers to the surface of the rubber, and the multiple plies of textile reinforcement provide flexibility. Series 7110 is also available in factory-fabricated and tested hose assemblies in popular configurations.
