254-0002 - Miller Smith 250 Series Silverline High Purity CO2 Regulator, Back Mount

Reliable CO2 Delivery for Bulk Systems

When your shop or facility relies on bulk liquid cylinders for gas supply, you need a regulator that fits correctly and stands up to the job. The Miller Smith 254-00-02 Silverline Regulator is designed specifically for the professional welder and fabricator using liquid cylinders. Unlike standard regulators that stick out awkwardly from the side, this unit features a rear-entry (back mount) CGA 320 connection, allowing it to sit flush and secure against the cylinder ring. This design minimizes the risk of impact damage and keeps your setup streamlined and safe.

Corrosion is the enemy of precision, especially in shop environments. That is why Miller Smith has coated this entire regulator—body, bonnet, and gauges—in a durable nickel plating. It stays looking new and working smoothly even in tough conditions. But the real workhorse feature is inside: a stainless steel diaphragm. When drawing gas from a liquid cylinder, temperatures can drop rapidly. Rubber diaphragms can stiffen and cause pressure fluctuations, but the stainless steel diaphragm in the 254-00-02 remains flexible and accurate, giving you a consistent flow of CO2 every time you pull the trigger.

Reading your pressure settings shouldn't require a flashlight and a magnifying glass. This regulator comes equipped with oversized 2-1/2 inch gauges that are easy to read from a distance, letting you check your tank levels and output pressure at a glance. Additionally, the exclusive Sure-Seat™ filtered seat technology protects the internal components from debris, meaning you spend less time fixing leaks and more time working. Whether you are running a central distribution system or a single station off a liquid dewar, this regulator delivers the reliability and purity your process demands.
