826-6627 - Miller Smith 820 Silverline High Pressure Regulator, 0-4000 PSIG, CGA 677

Reliable High-Pressure Control for Professionals

When your work demands precise control over high-pressure inert gases, the Miller Smith 826-66-27 Silverline regulator is the tool you can trust. Built for professionals in R&D laboratories, chemical plants, and manufacturing facilities, this regulator is designed to handle the tough jobs like purging, charging struts, calibration kits, and high-pressure vessel testing. Unlike standard regulators that might struggle with extreme pressures, the 820 Silverline series utilizes a heavy-duty piston sensor that stands up to 6000 PSIG inlet pressure while delivering a steady, adjustable output up to 4000 PSIG.

One of the standout features of this regulator is its ease of use. The low-torque adjusting knob makes dialing in the exact pressure you need smooth and effortless, even at the high end of the range. Because it is self-relieving, you can back off the pressure in a closed system without having to bleed lines manually, saving you time and hassle during complex testing procedures. The nickel-plated finish isn't just for looks; it protects your investment from corrosion and wear, ensuring that the regulator performs consistently year after year.

Safety and visibility are also top priorities in the design of the 826-66-27. The large 2-1/2 inch gauges are easy to read at a glance, helping you monitor cylinder and delivery pressures accurately. The bonnet includes a threaded vent port, allowing you to pipe away any vented gases, which is essential for maintaining safe air quality in confined workspaces. Whether you are working with Nitrogen, Argon, or other inert gases using a CGA 677 cylinder, this Miller Smith regulator provides the durability, precision, and safety features required for high-stakes industrial applications.
