OVERVIEW

Custom Hose Fabrication for the Pro Welder

Every serious fabricator knows that stock hose lengths don't always fit the shop layout. Whether you are rigging up a water-cooled TIG torch on a boom, running lines to a remote cooler, or just tired of dealing with stiff, cracked plastic hoses, the Weldcraft RMF-045-1000 bulk rubber hose is your answer. This is 1,000 feet of genuine, high-flexibility rubber hose that lets you build your leads exactly the way you want them.

The hose features a 5/16" ID (0.313") and a 1/2" OD (0.500"), which is the sweet spot for high-flow water cooling lines on heavy-duty torches. Unlike cheaper vinyl tubing that gets stiff in the cold and soft in the heat, this Weldcraft rubber hose maintains its flexibility and resists kinking. This means less drag on your wrist when you're manipulating the torch and less worry about cutting off your coolant flow if you step on the line.

Having a spool of this in the shop means you are never stuck waiting for a replacement part when a line blows. You can cut exactly what you need, crimp or clamp on your fittings, and get back to striking arcs in minutes. It's also perfect for extending your reach beyond the standard 12 or 25-foot packages. Upgrade your rig with the reliability of Miller/Weldcraft rubber and take control of your equipment setup.

Why Welders Choose Rubber

  • Superior Feel: Drastically more flexible than PVC, reducing torch drag.
  • Heat Resistance: Won't melt instantly if it accidentally brushes a hot part.
  • Durability: Stands up to shop grime, coolant, and physical abuse.

FAQ

The inner diameter (ID) is 0.313 inches, which is approximately 5/16 of an inch.

The outer diameter (OD) is 0.500 inches, or 1/2 inch. You should select ferrules or clamps sized for 1/2" OD hose.

This specific SKU (RMF-045-1000) is a bulk spool containing 1000 feet of hose. It is intended for high-volume users.

Yes, this rubber hose is often used for inert gas delivery in TIG and MIG welding, provided the pressure does not exceed the hose's rating.

Absolutely. It is designed to handle the coolant mixtures used in standard welding water coolers and recirculators.

No, this is a bulk spool of raw hose. Fittings, clamps, and crimps must be purchased separately.

No, the rubber material is non-conductive, which is essential for safety in welding environments where high frequency or high voltage is present.

Rubber hose is generally more flexible, especially in cold temperatures, and offers better resistance to kinking and incidental heat contact than vinyl.
