CGA350-2E - Miller CGA 350 Brass Tailpiece with Integrated Filter

Miller CGA350-2E Tailpiece: Precision Engineering for Gas Systems

The Miller CGA350-2E Tailpiece with Filter is a critical component designed for the safe and efficient transfer of specific industrial gases. Engineered to meet the rigorous standards of the Compressed Gas Association (CGA), this tailpiece is specifically machined for CGA 350 connections. CGA 350 is the designated standard for flammable gases such as Hydrogen, Methane, Natural Gas, and Carbon Monoxide. Ensuring you have the correct tailpiece is not just a matter of fit, but a fundamental safety requirement in gas regulation systems. This genuine Miller Electric part ensures that your equipment maintains its original specifications and safety ratings.

Constructed from high-quality brass, the CGA350-2E offers superior durability and resistance to corrosion, which is essential when dealing with industrial environments. The brass material provides the necessary malleability to create a metal-to-metal seal against the cylinder valve or manifold outlet, ensuring a leak-tight connection without the need for additional gaskets in many configurations. This metal-to-metal sealing capability is a hallmark of high-pressure gas fittings, requiring precision machining to prevent gas migration and potential hazards.

A standout feature of this specific tailpiece is the integrated filter. Gas cylinders, while generally clean, can sometimes contain particulate matter, rust, or debris from the cylinder walls or valve threads. Without filtration, these microscopic particles can enter the regulator at high velocity. This can score the regulator seat, leading to "creep" (where delivery pressure rises when the torch is off) or complete regulator failure. The sintered filter built into the Miller CGA350-2E acts as a first line of defense, trapping contaminants before they can reach the sensitive internal diaphragm and seat assembly. This simple inclusion significantly extends the service life of your regulator and maintains consistent flow performance.

For maintenance professionals and industrial gas users, replacing a worn or damaged tailpiece is a standard procedure during regulator overhaul. If the sealing surface of your current nipple is scratched or deformed, it can compromise the integrity of the connection. Installing a fresh Miller CGA350-2E restores the connection interface to factory standards. Whether you are assembling a new gas manifold or repairing an existing Miller regulator, this tailpiece provides the reliability and assurance expected from a top-tier welding manufacturer.
