Is the OXYGEN EN 559/ISO 3821 oxygen welding hose suitable for use with LPG, oils, or fuel-derived gases?

No. The OXYGEN EN 559/ISO 3821 oxygen welding hose is not suitable for use with LPG, oils, or fuel-derived gases. The product description explicitly states it is not recommended for gases produced from fuels, oils, and LPG. It is designed for oxygen service, with a black SBR/NR inner layer, synthetic braid reinforcement, blue SBR/NR outer layer, 20 bar working pressure and an operating temperature range of -20Â°C to +70Â°C. Using it with fuel gases or oil-contaminated gases risks material degradation and unsafe operation.

Can the OXYGEN EN 559/ISO 3821 oxygen welding hose be used safely in extreme weather or only within -20Â°C to +70Â°C?

The OXYGEN EN 559/ISO 3821 oxygen welding hose is designed and rated for safe operation within the specified temperature range of -20Â°C to +70Â°C. Its construction (SBR/NR inner and outer layers with synthetic braid) gives good resistance to kinks and weather conditions, but the manufacturerâs stated operating temperature should be respected. Use outside -20Â°C to +70Â°C may impair flexibility, pressure performance and safety; therefore it should not be assumed safe for extreme temperatures beyond that range. Also avoid use with gases produced from fuels, oils or LPG as noted.

Does the OXYGEN EN 559/ISO 3821 oxygen welding hose resist oil or fuel vapour contamination?

No. the OXYGEN EN 559/ISO 3821 oxygen welding hose is not resistant to contamination by oil or fuel vapours. According to the product description, it is specifically not recommended for gases produced from fuels, oils, and LPG. While the hose meets ISO 3821 standards and offers kink and weather resistance, its construction (black SBR/NR inner layer, synthetic braid reinforcement, blue SBR/NR outer layer) and intended use exclude exposure to oil or fuel vapours. Use of such vapours or fuel-derived gases could compromise safety and performance.
