E99-347C43 - CGA 347 Stainless Steel Nipple

Reliable Gas Connections for High-Pressure Cylinders

When you are hooking up high-pressure gas cylinders for specialized welding or cutting applications, the quality of your fittings matters. The Miller E99-347C43 Tailpiece is a genuine Miller replacement part designed to get your equipment up and running safely. This specific tailpiece is built for CGA 347 connections, which are typically found on high-pressure cylinders (up to 5500 PSI) containing gases like Argon, Nitrogen, or Helium. If you are working with high-pressure supply bottles, you know that standard fittings just won't cut it; you need components rated for the job.

Constructed from durable stainless steel, this tailpiece is built to last. Stainless steel is tougher than brass, meaning it stands up better to the wear and tear of frequent cylinder changes. It also resists corrosion, which is vital if you are working in a shop environment where moisture or chemicals might be present. For welders and fabricators who require high-purity gas for TIG welding or laser cutting, using stainless steel fittings helps ensure that the gas stream remains uncontaminated by the fitting material itself. This tailpiece acts as the nipple that seats against the cylinder valve, creating the primary seal that prevents dangerous and costly leaks.

Replacing worn or damaged gas fittings is a key part of equipment maintenance. A damaged tailpiece can lead to gas leaks, inaccurate flow readings, or even safety hazards due to the high pressures involved. By choosing this genuine Miller OEM part, you can be confident that it will fit your Miller regulators and gas equipment perfectly. It is designed to slide into the nut and mate securely with the cylinder valve, providing a solid connection every time.

Don't compromise on safety or performance when dealing with high-pressure gases. Whether you are setting up a new manifold system for your shop or repairing a regulator that has seen better days, the Miller E99-347C43 Tailpiece is the right tool for the job. It ensures that your shielding gas gets from the tank to your torch without leaks, letting you focus on laying down the perfect bead.
