826-6600 - Miller Smith 820 Silverline High Pressure Analytical Regulator, 0-4000 PSI, 1/4 FNPT

Heavy-Duty High Pressure Regulation for Industrial Use

When your job requires managing extreme pressures with absolute confidence, the Miller Smith 826-66-00 Silverline Regulator is the equipment you trust. Built for the serious demands of industrial testing and specialty gas delivery, this regulator takes the guesswork out of high-pressure control. Unlike standard regulators that might struggle under heavy loads, the 826-66-00 utilizes a heavy-duty piston sensor. This design is far more durable than standard diaphragms when dealing with the mechanical stress of 4000 PSI delivery pressures, ensuring that your equipment doesn't fail when you need it most.

Durability is built into every inch of this unit. The entire body, bonnet, and gauge casings are nickel-plated brass. This isn't just for looks—it provides a tough shield against corrosion and wear, extending the life of the regulator even in harsh shop environments or chemical plants. It is rated for a massive 6000 PSI max inlet pressure, giving you plenty of headroom for various high-pressure supply sources. The 1/4" FNPT connections offer secure, leak-free compatibility with standard high-pressure fittings and hoses, making it easy to hook up for purging, charging struts, or pressure testing assemblies.

Miller Smith understands that usability matters on the job site. That's why this regulator features a self-relieving adjusting screw. This mechanism allows you to back off the pressure easily without fighting the torque, even when the system is pressurized—a huge advantage for dead-end testing setups. The gauges are oversized at 2-1/2 inches, making them easy to read at a glance so you can monitor your levels without squinting. Plus, if you are building a custom test bench, the body is tapped for rear panel mounting, giving you a clean, professional installation. For welders and technicians working with inert gases who need reliable high-pressure delivery, the 820 Silverline series is the proven choice.
