Oxy Acetylene Equipment

C&O can handle all your gas apparatus repairs.  We work with trained technicians in a dust free facility to get your torch or regulator back to you, looking and performing like new.


We offer reliable delivery to Maryland and southern PA, often the same or next day.  Whether 1 cylinder or 100, we charge a nominal flat fee, with no surcharges.  We can even deliver the other products we sell, like welding consumable and supplies, tools, abrasives, and safety equipment.
