OVERVIEW

Reliable CO2 Connections with Miller OEM Parts

The Miller CGA320-1P Nut is a critical component for professionals utilizing Carbon Dioxide (CO2) in their industrial or welding applications. Designed to meet the strict Compressed Gas Association (CGA) 320 standards, this inlet nut ensures a safe and secure interface between your gas regulator and the gas cylinder valve. When dealing with compressed gases, the integrity of your connections is paramount to safety and efficiency. This genuine Miller part is engineered to precise tolerances, ensuring that threads engage smoothly and hold tight under pressure, minimizing the risk of leaks that can lead to gas wastage or safety hazards.

Durability is a key feature of the CGA320-1P. The nut features a high-quality plated finish. In industrial environments, exposure to moisture, humidity, and various shop chemicals can lead to the rapid deterioration of bare metal fittings. The plating on this nut acts as a protective barrier, significantly extending the lifespan of the component by resisting rust and corrosion. This makes it an excellent choice for workshops, manufacturing plants, and outdoor job sites where equipment is exposed to the elements.

As a genuine Miller Electric replacement part, this nut offers the peace of mind that comes with using OEM components. It is designed to fit perfectly with standard CGA 320 nipples and regulators, eliminating the guesswork often associated with generic aftermarket fittings. Whether you are setting up a new MIG welding station, maintaining a beverage carbonation system, or repairing an existing regulator, the Miller CGA320-1P provides the reliability and performance professionals demand. Proper maintenance of gas equipment involves regular inspection of fittings; replacing worn or damaged nuts with high-quality OEM parts is a simple step that ensures the longevity of your entire gas delivery system.

FAQ

The CGA 320 connection standard is specifically designed for Carbon Dioxide (CO2) gas cylinders.

No, this product is the nut only. The nipple or tailpiece is typically sold separately or reused if in good condition.

The plated finish provides corrosion resistance, protecting the nut from rust and wear in industrial or humid environments.

Yes, this is a genuine Miller Electric OEM replacement part, ensuring high quality and perfect fitment.

Yes, CGA 320 connections typically require a flat washer (usually fiber or nylon) to create a proper seal between the nipple and the cylinder valve.

No, Argon uses CGA 580 and Oxygen uses CGA 540. CGA 320 is exclusively for CO2 and will not fit other cylinder valves.

A standard large adjustable wrench or a dedicated cylinder wrench is recommended to tighten the nut securely without damaging the plating.

Yes, as long as the regulator uses a standard CGA 320 nipple/tailpiece, this nut should be compatible regardless of the regulator brand.
