572F82 - ESAB Grade RM Twin Welding Hose 3/16" x 12.5' B-B Fittings

Technical Overview of ESAB 572F82 Twin Welding Hose

The ESAB 572F82 is a premium-quality twin welding hose designed specifically for oxy-acetylene applications. Classified as Grade RM, this hose features a rubber construction that offers oil and flame resistance on the cover, while the inner tube is formulated for acetylene gas. It is crucial to note that Grade RM hoses are not suitable for use with alternate fuel gases such as propane or natural gas, which require Grade T hoses.

This specific assembly features a 3/16-inch inner diameter (ID), which is a standard size for light to medium-duty welding and cutting torches. The smaller diameter makes the hose lighter and more flexible than 1/4-inch alternatives, reducing operator fatigue during precision work. The hose length is 12.5 feet, making it an excellent choice for stationary bench work, manifold systems, or as a whip hose extension where long, heavy cables would be cumbersome.

The hose comes pre-assembled with standard B-Size fittings (9/16"-18 threads) on both ends (B-B configuration). The fittings are brass crimped for a secure, leak-proof seal. The oxygen line is green with right-hand threads, while the fuel line is red with left-hand threads (indicated by the notched nut), adhering to industry safety standards to prevent cross-connection. The Siamese design bonds the two hoses together to prevent tangling while allowing them to be separated near the torch for ease of movement.
