826-6609 - Miller Smith 820 Silverline High Pressure Piston Regulator, 0-4000 PSI, CGA 580

Heavy-Duty High Pressure Regulator for Industrial Testing

When your work demands extreme pressure control, the Miller Smith 826-66-09 Silverline Regulator stands ready to deliver. This high-pressure, single-stage regulator is built to tackle the toughest jobs in the industry, from high-pressure testing of pipeline systems to charging accumulators and struts. With a massive delivery range of 0-4000 PSIG and the ability to handle inlet pressures up to 6000 PSIG, this tool is a powerhouse for any welder or technician working with inert gases like Nitrogen or Argon.

The 826-66-09 distinguishes itself with a robust piston sensor design. In high-pressure applications, rubber or metal diaphragms can be a weak link, but the piston sensor offers unmatched durability and reliability. This ensures that the regulator maintains consistent pressure delivery without the risk of blowout or rapid wear, even under heavy use. The low-torque adjusting screw is self-relieving, making it incredibly smooth to dial in the exact pressure you need, which is critical when performing sensitive leak tests or calibration tasks.

Construction quality is top-tier, featuring a nickel-plated brass body and bonnet. This plating not only gives the regulator a professional, clean look but also provides a hard-wearing shield against corrosion and shop abuse. The gauges are also nickel-plated and sized at a large 2-1/2 inches, making them easy to monitor from across the bench or equipment. The regulator comes equipped with a CGA 580 connection, the standard for inert gases, ensuring compatibility with your existing cylinders.

Versatility is key in the shop, and this regulator includes features that adapt to your setup. The body is tapped for rear panel mounting, allowing for secure installation in test benches or gas distribution panels. Additionally, the bonnet includes a capturable vent port, giving you the option to pipe vented gas away safely—a smart feature for enclosed workspaces. Superseding the legacy 853-66-09-00-00 model, this Silverline regulator represents the modern standard for high-pressure gas control.
