Parker SIAMEEZ® Grade R Twin Line Welding Hose (Series 7126)

Red – Acetylene Only; Green – Oxygen Line ARPM IP-7

SIAMEEZ Grade R Twin Line Welding Hose Series 7126

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