There are two basic types of gas pressure regulators: single-stage and two-stage. Single-stage pressure regulators reduce the cylinder pressure to the delivery or outlet pressure in one step. Two-stage pressure regulators reduce the cylinder pressure to a working level in two steps.
Each regulator is designed to fit a specific type of cylinder valve and a regulator that fits one type of valve will not fit any of the others. The valve on Propane cylinders has a screw thread and only accommodates Propane regulators.
Using a regulator flowmeter or flow gauge regulator is essential for welding because it’s necessary to know the cubic feet per hour or liters per minute a gas is flowing to provide adequate shielding of the weld metal deposit, bead shape, and penetration and to properly align with your welding parameters.

cylinder connections are used for connecting various items of a gas handling apparatus, such as pressure regulators or pigtails, directly to cylinders. The actual connection depends on the gas in the cylinder and is designated by a three-digit Compressed Gas Association (CGA) Number
Cylinder connections consist of a CGA nut and CGA nipple and in some cases a washer for sealing purposes. SGC offer cylinder connections in a wide variety of configurations and materials to fit your application.
Configuration available either brass or stainless steel
