OVERVIEW

ESAB 583F83 Grade RM Twin Welding Hose Overview

The ESAB 583F83 is a premium-quality twin welding hose designed for industrial oxy-fuel applications. Manufactured under the renowned Oxweld brand, this hose assembly is engineered to meet the rigorous demands of professional fabrication environments. The hose features a "Siamese" double-line construction, bonding the oxygen and fuel lines together to prevent tangling and ensure a tidy workspace. This specific model is classified as Grade RM, indicating it has an oil-resistant cover and a non-oil-resistant tube, making it specifically suitable for Acetylene gas service. It is not recommended for use with alternate fuel gases like propane or propylene, which require Grade T hose.

With a 1/4-inch inner diameter (ID), this hose provides sufficient gas flow for a wide range of cutting torches, welding handles, and heating nozzles. The 25-foot length is the standard configuration for most shop carts and stationary bench setups, offering enough reach to work around large assemblies without creating excessive slack or tripping hazards. The hose comes pre-fitted with standard B-Size (5/8"-18) connections—right-hand thread for oxygen and left-hand thread for fuel—ensuring compatibility with the vast majority of industrial regulators and torches in North America.

Procurement specialists should note that this product is sold as a complete assembly, ready for immediate deployment. The factory-crimped ferrules provide a superior safety margin compared to field-repair kits, reducing the liability associated with gas leaks. The rubber composition is formulated to resist abrasion, weather, and ozone, ensuring a long service life in MRO (Maintenance, Repair, and Operations) environments. When stocking this item, it serves as a direct replacement for worn or damaged hoses on standard oxy-acetylene outfits.

FAQ

No, this is a Grade RM hose designed specifically for Acetylene. For alternate fuels like Propane, you must use a Grade T hose to prevent deterioration of the inner tube.

The hose comes with standard B-Size fittings (5/8"-18 thread). The oxygen fitting has right-hand threads, and the acetylene fitting has left-hand threads (indicated by a notch on the nut).

The inner diameter (ID) is 1/4 inch, which is the standard size for most industrial welding and cutting applications.

Yes, the 1/4-inch diameter supports sufficient flow for most heavy-duty cutting torches and heating nozzles.

No, this SKU is for the hose assembly only. Flashback arrestors must be purchased separately and installed at the regulator or torch end.

The hose is 25 feet long.

The hose is color-coded: Green is for Oxygen, and Red is for the Fuel gas (Acetylene).

Grade RM hose has an oil-resistant cover but a non-oil-resistant tube. It should be kept away from excessive oil and grease exposure.
