CGA320-2E - Miller CGA 320 CO2 Regulator Tailpiece with Filter

Reliable CO2 Connections for MIG Welding

Keep your welding setup running smoothly with the Miller CGA320-2E Tailpiece, With Filter. If you are welding with straight CO2—common for deep penetration on steel or cost-effective MIG welding—your regulator needs a connection that is tough, safe, and reliable. This genuine Miller replacement part ensures your regulator connects securely to standard CO2 cylinders, preventing leaks that waste gas and cause porosity in your welds.

Over time, the threads and sealing faces of regulator connections can get dinged, scratched, or worn down from constant cylinder swaps. A damaged tailpiece is a common cause of frustrating leaks. Swapping out your old, worn nipple for this brand-new brass tailpiece restores the integrity of your connection. Because it is a Miller OEM part, you can trust the machining tolerances to be perfect, ensuring it fits your Miller regulator assembly without hassle.

Protect Your Gear

The "With Filter" feature is a game-changer for equipment longevity. Dirty gas can ruin a good regulator in seconds. This tailpiece includes a built-in filter that stops dirt, metal shavings, and cylinder scale from shooting into your regulator. This protection helps maintain consistent gas flow, which is essential for a stable arc and clean weld bead. By catching debris at the source, you avoid costly repairs or the need to replace your entire flowmeter setup prematurely.

Installation and Use

Installing the CGA320-2E is straightforward for any welder familiar with regulator maintenance. It fits into the inlet side of your regulator body (check your specific model for thread compatibility) and pairs with a standard CGA 320 nut. Remember, CO2 connections always require a washer (the little flat disc) to seal properly. Whether you are setting up a new rig or refurbishing an old shop workhorse, this tailpiece is the professional choice for safe and clean gas delivery.
