Welding cylinders and accessories are used to store, transport, and dispense compressed gas for welding and cutting applications. Compressed gas cylinders hold a supply of fuel gas or oxygen for welding or cutting tasks. Gas cylinder collars protect regulators and cylinder valves from damage during storage or transport. Cylinder stands help prevent safety hazards by securing cylinders to keep them from tipping, falling, or rolling during storage. Cylinder brackets mount welding gas cylinders to walls to secure them when not in use and keep floor and table surfaces clear.
