Welding Industrial Hoses | Parker | SIAMEEZ® Grade R Twin Line Welding Hose | 7126 Series


Series 7126 is a twin line welding hose; the red hose 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. The cover is resistant to abrasion, heat, mild chemicals and ozone. Series 7126 is also available in factory-fabricated and tested hose assemblies in popular configurations.
