OVERVIEW

High-Performance Grade RM Twin Welding Hose

The ESAB 572F83 is a premium-quality twin welding hose designed specifically for oxy-acetylene applications. Engineered to meet the rigorous demands of industrial environments, this hose features a Grade RM construction. Grade RM hoses are manufactured with a rubber tube and cover that are specifically resistant to the chemical properties of acetylene gas. It is critical for safety and compliance that Grade RM hoses are used exclusively with acetylene and not with alternate fuel gases like propane or propylene, which require Grade T hoses. This product ensures that your facility maintains safety standards while providing reliable gas delivery to your welding and cutting equipment.

This assembly features a 3/16-inch inner diameter (ID), which is an excellent choice for light to medium-duty applications. Compared to heavier 1/4-inch hoses, the 3/16-inch profile offers significantly reduced weight and improved flexibility. This allows operators to manipulate the torch with greater precision and less fatigue over long shifts. The hose comes in a standard 25-foot length, making it ideal for cylinder carts and stationary bench work where excessive hose length would otherwise create a tripping hazard or pressure drop issues.

The hose is supplied as a siamesed twin line, meaning the oxygen (green) and fuel (red) lines are molded together to prevent tangling, yet can be separated at the ends for connection to equipment. It comes pre-fitted with standard B-size (9/16"-18) brass nuts and ferrules, factory-crimped to ensure a pressure-tight seal that exceeds the reliability of field-repair clamps. The fittings are color-coded and threaded (right-hand for oxygen, left-hand for fuel) to prevent cross-connection accidents. This hose is an essential component for MRO operations, fabrication shops, and maintenance departments requiring dependable oxy-acetylene equipment.

FAQ

Grade RM indicates that the hose is designed specifically for Acetylene gas. The inner tube and cover are oil and flame resistant but are not compatible with alternate fuels like propane or natural gas.

No. You must use a Grade T hose for Propane, Propylene, or Natural Gas. Using Grade RM with propane can cause the inner rubber tube to deteriorate and leak.

This hose comes with standard B-Size fittings (9/16"-18 threads). This is the most common connection size for industrial regulators and torches.

Yes, for most standard applications. 3/16" hose provides sufficient flow for welding tips and cutting attachments up to medium duty. For very heavy cutting or extremely long runs, 1/4" might be required.

Yes, this hose assembly features factory-crimped brass ferrules and nuts for a secure, safety-rated connection.

The hose is color-coded: Green is for Oxygen (right-hand thread) and Red is for Acetylene (left-hand thread).

Standard welding hoses are typically rated for a maximum working pressure of 200 PSI, which is well above standard operating pressures for oxy-acetylene welding.

Warranty terms depend on the manufacturer (ESAB), but generally cover defects in material and workmanship upon receipt.
