174668 - Miller Air Regulator and Filter Combo 1/4 NPT

Keep Your Equipment Running Smoothly

Don't let wet, dirty air ruin your cuts or damage your expensive machinery. The Miller 174668 Regulator/Filter is the perfect solution for welders and fabricators looking to ensure their air supply is clean, dry, and at the perfect pressure. This genuine Miller part is designed to replace worn or damaged regulators on compatible equipment, restoring your machine's ability to function efficiently and effectively.

Dual-Action Performance

This unit is a workhorse that performs two jobs at once. First, it regulates your air pressure. With a capacity to handle up to 250 PSIG coming in, it allows you to step that pressure down to a usable working level, with a max outlet of 100 PSIG. Second, it filters the air. Compressed air often contains water vapor and debris from the compressor tank. This device helps trap those contaminants before they enter your plasma cutter or air tool, extending the life of your consumables and internal components.

Easy Installation and Compatibility

Featuring standard 1/4" NPT connections, the Miller 174668 is easy to plumb into your existing setup. It is commonly used as a direct replacement for the air regulation systems found on various Miller plasma cutters and welding power sources. Verifying your machine's serial number or parts manual is always recommended to ensure this is the exact part you need, but its standard specs make it a versatile choice for many air regulation needs.

Why Choose Genuine Miller Parts?

When you choose genuine Miller parts, you aren't just buying a piece of metal; you are buying peace of mind. OEM parts are built to the exact tolerances required for your machine, ensuring a leak-free fit and accurate pressure readings. Avoid the hassle of generic knock-offs that might fail under pressure. Stick with the brand you trust to keep your shop operational and your cuts clean.
