110-4007 - Miller Smith Silverline 110 Series Regulator, CGA 510, 15 PSI Delivery

Reliable Gas Control for Your Shop

When you need a regulator that just works, day in and day out, the Miller Smith 110-40-07 Silverline Series is a solid choice for your general welding and industrial needs. Built to handle the rigors of the shop floor, this regulator combines a tough exterior with reliable internal components. If you are working with inert gases like Nitrogen, Argon, or CO2 and require a setup with a CGA 510 connection, this unit provides the consistency you need without the high price tag of ultra-high-purity lab equipment.

The first thing you'll notice is the build quality. Unlike cheaper regulators that use die-cast parts, the Miller Smith 110-40-07 is machined from solid brass bar stock. This means it can take a bump or two without cracking or losing calibration. The entire unit—body, bonnet, and gauges—is plated to resist rust and corrosion, keeping it looking professional and functioning smoothly for years. The large 2-1/2 inch gauges are easy to read, even from a distance, so you always know exactly how much gas you have left and what your output pressure is.

Performance-wise, this single-stage regulator offers a steady 15 PSI output range, ideal for many standard applications. The internal filtered seat is a great feature that often goes unnoticed but saves you money in the long run; it traps dirt and debris before they can damage the regulator's seat, preventing leaks and creep. Whether you are setting up a purge line, running pneumatic tools, or managing shielding gas, the Miller Smith 110-40-07 delivers the reliability Miller is famous for. It's a workhorse tool for real-world welders and fabricators.
