Commercial gas hoses are the only appropriate connections for commercial equipment.Sometimes operators buy residential gas hoses to save money for their gas connections.This may seem like a cost-saver, but think about the costs down the line.The gas hose on movable equipment could always crack or break.This is a dangerous scenario with potential to cause equipment or facility fires.
Safety is the first reason not to use residential gas hoses in a commercial setting. Residential gas hoses are designed for a one time connection. These types are not to be removed until the connected home appliance is no longer operational.
