Our flowmeter regulators are 100-percent tested and inspected, and provide unmatched gas control and accuracy. Flowmeter regulators are available in multiple scales for use with all major shielding gases to cover most MIG or TIG welding applications. Our premium flowmeter regulators feature an exclusive self-centering ball guide which provides accurate readings even if tipped. This ensures optimum weld quality and gas savings. Others use a non-self-centering flow tube ball that tends to float off center causing actual gas flow to be over two times greater than indicated. Series 40 single-stage regulators comprise a complete line of versatile regulators for welding, cutting, heating and other industrial applications. Heavy-duty construction and simplified design provide high gas flow and longer trouble-free operation. Stainless steel diaphragm allows use with liquid gases

• Resin bonnet insert: Allows smooth, easy adjustment even at high-pressure levels
• 2-1/2 Inch gauge
• Color-coded labels: Supply performance capabilities, easy gas service identification and technical information
• External relief valve: Protects regulator from damage due to inadvertent high-pressure surge. Relief valve will release excessive pressure and automatically reset
• Nickel-plated bonnet: along with brass body protect against corrosion
• Shatter-resistant gauge lenses: 2.5 Inch corrosion-resistant polished brass gauges with shatter-resistant polycarbonate lenses
• Dual filters including Sure Seat™: Protect high-pressure seat from debris for reliable operation and long service life
• Heavy-duty construction and simplified design provide high gas flow and longer trouble-free operation
• Stainless steel diaphragm allows use with liquid gases
• Stainless steel diaphragm: Resists corrosion, leaking and freeze-up if used with liquid (cryogenic) gases for extended service life
• 3 yr. limited warranty
• For welding, cutting, heating and other industrial applications
