OVERVIEW

Reliable Acetylene Connections

When you are setting up your oxy-acetylene rig or repairing a regulator, the integrity of your connections is paramount for safety and performance. The Miller CGA300-3 Brass Tailpiece is the exact part you need for connecting to commercial acetylene cylinders (CGA 300). Don't risk leaks with worn-out or mismatched fittings; this genuine Miller part ensures a perfect seat every time.

Built for the Shop
Made from solid brass, this 2.50-inch tailpiece stands up to the daily abuse of the welding shop. It resists stripping and deformation, ensuring that your regulator stays securely attached to the cylinder. It is designed to slide easily into the appropriate nut and seat firmly against the valve outlet, giving you peace of mind while you work.

Easy Replacement
Over time, the sealing surfaces of tailpieces can become scratched or dented, leading to gas leaks. Swapping out your old tailpiece with the Miller CGA300-3 is a quick and cost-effective way to restore your equipment to safe operating conditions. Keep a few in your spare parts bin so you are never stuck with a leaky rig when a job needs to get done.
