Autogene EN ISO 3821 NR/L – NB/L 20 is a single line hose designed for delivery of welding and allied process gases with colored cover to match the EN specs indication: Red for Acetylene and Blue for Oxygen. Can be used either in industrial and domestic application and its high grade materials enable a safe use in all circumstances, furthermore it exceeds the stantard prescribed values on backfire test. The non-blooming tube minimizes the migration of combustible waxes or plasticizers to the surface of the rubber and the cover is resistant to abrasion, heat, sparks, ozone and mild chemicals. It is ideal for all those applications where the fuel gas and oxygen sources are separated and a twin hose is not practical.
