Secure Your Fuel Connections

Keep your Smith Little Torch running safely and efficiently with the Miller R3A Left-Hand Hose Nut. If you've noticed wear on your existing fittings or are building up a custom hose assembly, this genuine replacement part is exactly what you need.

This brass nut is designed specifically for the fuel side of your torch setup, featuring the standard Left-Hand threads that distinguish fuel lines from oxygen lines.

The R3A nut ensures that your fuel gas delivery is uninterrupted and leak-free. Made from durable brass, it stands up to the daily rigors of the shop environment. Whether you are using Acetylene, Propane, or Hydrogen, this nut provides the secure bite you need on your hose connection.

Ready for the Shop

This part is a must-have for your spare parts kit. Hose fittings can get damaged from drops, overtightening, or just years of service. Having a spare R3A nut on hand means you won't be shut down by a minor hardware failure. It connects easily—remember, it's a left-hand thread, so turn it counter-clockwise to tighten—and gets you back to soldering and brazing in no time.
