Is the Oxygen Welding Hose ISO 3821 suitable for use with natural gas and compressed air as well as oxygen?

Yes. The Oxygen Welding Hose ISO 3821 is suitable for use with oxygen, natural gas and compressed air. Manufactured to EN ISO 3821, its construction (black SBR/EPDM inner layer, PVA reinforcement and blue EPDM outer cover) provides gas impermeability, strength and weather/abrasion resistance. It supports working pressures up to 20 bar and an operating temperature range of -30°C to +80°C, making it safe and reliable for oxy-fuel welding as well as natural gas and compressed air applications.

Can the Oxygen Welding Hose ISO 3821 be safely used outdoors in extreme temperatures between -30°C and +80°C?

Yes. The Oxygen Welding Hose ISO 3821 can be safely used outdoors in extreme temperatures between -30°C and +80°C. It is manufactured to EN ISO 3821 and specifically rated for an operating temperature range of -30°C to +80°C. The hose’s inner SBR/EPDM rubber resists wear and gas permeation, the PVA reinforcement ensures strength under pressure (working pressure up to 20 bar), and the smooth blue EPDM outer layer protects against abrasion, weather and mechanical stress—features that support reliable, safe outdoor use across that temperature span. Ensure regular inspections and proper handling to maintain safety and performance.
