Is ACETYLEN EN 559/ISO 3821 acetylene welding hose suitable for use with LPG or fuel-derived gases?

No. ACETYLEN EN 559/ISO 3821 acetylene welding hose is not suitable for use with LPG or other fuelâderived gases. The product description explicitly states it is made for acetylene to ISO 3821 and is "Not recommended for gases produced from fuels, oils, and propaneâbutane (LPG)." Using it with those gases could lead to chemical incompatibility, accelerated hose degradation and safety hazards. Use a hose specifically rated for LPG or fuel gases.

Can ACETYLEN EN 559/ISO 3821 acetylene welding hose be used with oils, fuels, or propane-butane (LPG)?

No. ACETYLEN EN 559/ISO 3821 acetylene welding hose is not recommended for gases produced from fuels, oils, or propaneâbutane (LPG). It is designed for acetylene per ISO 3821 and its materials (black SBR/NR inner, synthetic braid reinforcement, red SBR/NR outer) and specifications (working pressure 20 bar, temperature -20Â°C to +70Â°C) make it unsuitable for use with fuelâbased gases or LPG.

Can ACETYLEN EN 559/ISO 3821 acetylene welding hose be used safely with fuel-derived gases or LPG mixtures?

No. ACETYLEN EN 559/ISO 3821 acetylene welding hose is designed specifically for acetylene and similar gases per ISO 3821. The product description explicitly states it is not recommended for gases produced from fuels, oils, or propaneâbutane (LPG) mixtures. Using it with fuel-derived gases or LPG could compromise safety and performance because the hose materials and construction (black SBR/NR inner layer, synthetic braid reinforcement, red SBR/NR outer layer) are formulated for acetylene service, not for the chemical compatibility or swelling effects that fuel oils and LPG can cause. Always follow the manufacturerâs recommendations and choose hoses approved for fuel gases/LPG to ensure safe working pressure limits (20 bar) and operating temperature range (â20Â°C to +70Â°C) are not violated.
