Features Clearly Visible: The surface of the gas welding regulator has a protective film, the scale is clearly visible, and the transparent panel allows us to easily read the data, which is very convenient. Non-slip Design: The carbon dioxide pressure reducer is a large handle switch with a non-slip design, which is more labor-saving and efficient when used. Main Purpose: The CO2 regulators gauges is an essential accessory of the pneumatic control valve. The main function is to reduce the pressure and stabilize it to a fixed value, so that the regulator can obtain a stable air source power for adjustment and control. Good Sealing Performance: The carbon dioxide pressure reducer is suitable for gas welding, cutting, chemical and other processes, and has the characteristics of compact structure, beautiful appearance and good sealing performance. Stronger and More Durable: The pressure reducer is made of zinc alloy material, and the interface link is equipped with brass filter, cap, outlet nozzle, zinc alloy casting, which is more durable. Features: 1.Suitable for gas welding, cutting, chemical and other process. 2.The surface has protective film, the scale is clearly visible, not easy to fade 3.Compact structure, beautiful appearance,and great sealing performance 4.Big handle switch: anti-skid design, more saving labor 5.Valve body is made of zinc alloy, inlet pipe with sintered brass filter, oxygen cap, outlet nozzle, zinc alloy casting, thicker and durable 6.Product use: the pressure reducing valve pneumatic control valve is a necessary accessories, the origin of the main effect is to reduce the pressure and stability to a fixed value so that the regulator can obtain stable gas source power for regulating control Specifications: Material: Zinc alloy + brass Applicable medium: Carbon dioxide Measuring range: 0-1MPa, 0- 25MPa Big cap thread: G5/8 Outlet nozzle: 8mm Size: 14.5 x 14cm / 5.71 x 5.51in Weight: 762g Package included: 1x CO2 Pressure Regulator Note: Before purchase, it is required to confirm that the flat head model of the cylinder is QF-2 before normal use.
