Smith 35-125-540 Series 30 Two-Stage Oxygen Regulator CGA 540

Miller Smith 35-125-540 Two-Stage Oxygen Regulator

Experience the ultimate in gas control with the Miller Smith 35-125-540 Two-Stage Oxygen Regulator. Designed for professional welders and fabricators who demand accuracy, this Series 30 regulator delivers a "set it and forget it" performance. Unlike single-stage regulators that allow outlet pressure to rise as the cylinder pressure falls, this two-stage unit maintains your set pressure from a full cylinder down to empty. This means you get a consistent flame profile throughout your entire cut or weld, without the hassle of stopping to tweak your regulator settings.

The 35-125-540 is built to last in the toughest shop environments. It features a solid brass body and a nickel-plated bonnet that resists corrosion and wear. Inside, Smith's legendary Sure-Seat filtered seat technology protects the heart of the regulator. By preventing metal shavings, dirt, and other debris from damaging the high-pressure seat, Smith ensures that this regulator provides years of dependable, leak-free service. The diaphragm is crafted from a reinforced neoprene composite, offering superior flexibility and response to pressure changes compared to stainless steel diaphragms found in lesser units.

This regulator is rated for a maximum inlet pressure of 3000 PSIG and provides a delivery range of 0-125 PSIG, making it versatile for a wide range of cutting, heating, and welding tasks. It connects via a standard CGA 540 fitting. The large, easy-to-read 2-inch gauges feature polished brass cases and shatter-resistant polycarbonate lenses, combining style with rugged safety. An auto-reset safety relief valve provides an added layer of protection against high-pressure surges. Backed by a 3-year limited warranty and made in the USA, the Smith 35-125-540 is an investment in quality that pays for itself through improved efficiency and reduced equipment downtime.
