Frequently Asked Questions

What do the hose colors mean on an oxyfuel setup?
In the US, green hoses are used for oxygen and red hoses for fuel gases (acetylene, propane, etc.). This color coding, combined with right-hand threads on oxygen and left-hand threads on fuel gas, makes misconnection much harder. The color convention is an industry standard — never swap or repurpose a hose from one gas service to another, as residual contamination can create a fire hazard.
What is the maximum safe working pressure for standard oxyfuel gas hoses?
Standard oxy-fuel gas hoses are rated to a maximum working pressure of 200 psig. Although higher pressures were once permitted on older equipment, current hose and fitting standards do not allow use above 200 psig. For acetylene specifically, the gas itself should never exceed 15 psig at the point of use, well below the hose pressure limit.
Can I use an old acetylene hose with propane or vice versa?
No — older acetylene hoses may be made from materials (rubber compounds) that are incompatible with LP gases like propane. Propane and other LP gases can degrade some rubber formulations, causing the hose to swell or crack from the inside. Always use a hose specifically rated for the fuel gas you are running. This is listed in the hose specifications; look for ratings that include propane/LP or MAPP if you use those gases.
How long of a hose do I need, and does length affect performance?
Hose length creates pressure drop, particularly with gases that run at low delivery pressures like acetylene. For most shop work, 12.5 ft or 25 ft twin-hose sets are standard. If you need longer runs (50 ft or more), compensate by slightly increasing the regulator delivery pressure to maintain the correct working pressure at the torch. Never coil excess hose tightly around a cylinder — support hoses off the ground and away from hot metal.
How do I repair a damaged gas hose, and when should I replace it instead?
Surface cuts or abrasion damage that hasn't breached the inner tube can sometimes be protected with hose tape as a temporary measure, but a hose with any crack, hole, or exposed inner tube must be replaced — not repaired with tape. If the damage is mid-hose, a section can be cut out and rejoined with approved brass hose repair fittings (barbed connectors with swaged crimps). Do not use duct tape or general repair tape on high-pressure gas hoses.
