E99-350C43 - CGA 350 Stainless Steel Nipple Tailpiece

Reliable Gas Connections for Professional Welders

When you are setting up your rig for specialized welding or cutting applications involving Hydrogen or Methane mixtures, you need fittings you can trust. The Miller E99-350C43 Tailpiece is a robust stainless steel nipple designed for CGA 350 connections. In the welding and fabrication industry, equipment downtime due to leaky or worn-out fittings is a frustration that costs time and money. This Miller OEM part is built to withstand the rigors of daily industrial use, ensuring that your gas flow remains consistent and your work environment remains safe.

The choice of stainless steel for this tailpiece is significant. While many standard fittings are brass, stainless steel offers superior strength and durability. It is much harder than brass, meaning the sealing surface is less likely to deform or mar after repeated tightening and loosening cycles during cylinder changes. This resilience translates to a longer service life and fewer replacements over time. Furthermore, if you are working in environments with high humidity or exposure to corrosive fumes, the stainless steel construction resists rust and oxidation, ensuring that the fitting remains clean and functional. This is particularly important for maintaining the purity of your shielding or fuel gases, as contaminants from a corroding fitting can negatively impact weld quality.

Safety is the number one priority when handling fuel gases associated with CGA 350. A compromised tailpiece can lead to dangerous leaks at the regulator connection. By replacing worn or damaged nipples with the Miller E99-350C43, you restore the integrity of your connection. This tailpiece is designed to fit perfectly inside a standard CGA 350 nut, providing a secure anchor for your regulator or hose assembly. Whether you are a pipe welder, a fabrication shop manager, or a maintenance technician, investing in high-quality connection parts like this Miller tailpiece is a small step that makes a big difference in the safety and efficiency of your operations.
