823-0027 - Miller Smith 820 Silverline High Pressure Regulator CGA 677 0-500 PSI

Heavy-Duty High-Pressure Regulator for Industrial Testing

When your shop requires reliable high-pressure gas delivery for testing or purging, the Miller Smith 823-00-27 Silverline Regulator is the tool for the job. Built to handle the rigors of industrial environments, this single-stage regulator is designed to control noncorrosive inert gases with a delivery pressure up to 500 PSIG. It connects securely to high-pressure cylinders via a CGA 677 fitting, rated for inlet pressures up to 6000 PSIG, making it an essential component for high-pressure testing rigs and equipment calibration stations.

Durability is a key feature of the Silverline series. The entire assembly—including the body, bonnet, and gauges—is nickel-plated. This tough coating protects the brass substrate from corrosion and daily wear and tear, extending the service life of your equipment. Inside, a robust piston sensor replaces the delicate diaphragms found in standard regulators. This design choice ensures structural integrity under high pressure, reducing the risk of failure and maintenance downtime. You can trust this regulator to perform consistently, day in and day out.

The 823-00-27 is designed with the operator in mind. It features a low-torque, self-relieving adjusting screw that makes dialing in the exact pressure effortless. The self-relieving feature is a massive time-saver, allowing you to back off pressure in a closed system without having to bleed the line manually. Visibility is also improved with oversized 2-1/2 inch gauges, which are easy to read even when you are working a few feet away from the cylinder.

Safety and versatility are standard. The bonnet comes with a captured vent port (1/16" FNPT), giving you the option to pipe vented gases away from your workspace—a critical safety feature when working in confined areas. The body is also tapped for rear panel mounting, allowing for clean, permanent installation in test benches or gas manifolds. 100% tested at maximum rated pressure and cleaned for oxygen service standards, the Miller Smith 823-00-27 offers the peace of mind and performance professional welders and technicians demand.
