OVERVIEW

Reliable Connection for Hydrogen Service

The Miller CGA350-1 Nut is a critical component for establishing secure connections in compressed gas systems utilizing Hydrogen (H2) and other compatible fuel gases. Manufactured to strict Compressed Gas Association (CGA) standards, this nut is designed to mate perfectly with CGA 350 cylinder valves and nipples, ensuring a leak-free seal essential for safety in industrial and laboratory environments.

Constructed from high-quality brass, the CGA350-1 offers excellent durability and resistance to galling. The nut features the standard left-hand thread configuration mandated for fuel gases, providing a physical safety barrier against accidental connection to oxygen or inert gas lines. This specific fitting is rated for the pressures typically associated with hydrogen cylinders and is suitable for use in manifold systems, pigtails, and regulator inlet assemblies.

Whether you are maintaining a laser cutting gas supply, a laboratory analytical setup, or a standard industrial welding station, using genuine Miller replacement parts ensures compatibility and reliability. The CGA350-1 is precision-machined to tolerate the torque required for a tight seal without compromising the integrity of the fitting threads. Ensure your gas distribution system remains compliant and safe with this essential replacement part.

FAQ

CGA 350 is the standard connection for Hydrogen, Methane, Natural Gas, Carbon Monoxide, and Ethylene.

The CGA350-1 nut has left-hand threads, which is standard for fuel gas connections to prevent cross-connection with oxygen.

It is made of durable brass, which is the standard material for most compressed gas fittings due to its spark resistance and durability.

No, this product is the nut only. The nipple must be purchased separately if needed.

No, Oxygen regulators use a CGA 540 connection which has right-hand threads. This CGA 350 nut will not fit.

Left-hand thread nuts, like the CGA 350, typically have notches cut into the corners of the hex for easy visual identification.

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

You will need a wrench of the appropriate size to tighten the nut onto the cylinder valve or manifold fitting. Remember to turn counter-clockwise to tighten due to the left-hand thread.
