RH-2401 - 3/8 Inch Grade R Oxy-Acetylene Twin Hose Assembly - 12.5 ft

Heavy-Duty Grade R Twin Hose for High-Flow Applications

The RH-2401 Twin Hose is a robust solution for welders requiring high-volume gas flow in oxy-acetylene cutting and welding operations. Unlike standard light-duty hoses, this assembly features a 3/8-inch internal diameter, significantly reducing pressure drop over the length of the line. This characteristic is vital when running high-capacity heating nozzles or cutting thick plate, ensuring your flame remains stable and potent without starving the torch of fuel or oxygen.

This hose is manufactured to Grade R specifications. It features a smooth, synthetic rubber tube and a durable cover that resists flame, heat, and abrasion. It is important to note that Grade R hoses are designed exclusively for use with acetylene gas. The internal tube material is not compatible with alternate fuel gases like propane or propylene, which can cause the rubber to deteriorate rapidly. For shops strictly utilizing acetylene, Grade R offers a cost-effective and high-performance solution.

The assembly is terminated with high-quality brass B-size fittings (9/16"-18 threads), the industry standard for most medium to heavy-duty regulators and torches. The fittings are factory-crimped to ensure a leak-proof seal and exceed safety standards for pull strength. The 12.5-foot length is ideal for fixed station setups, minimizing pressure loss and reducing the risk of hose damage from floor traffic. Whether you are outfitting a new cutting station or replacing worn-out lines, this hose delivers the durability and performance professional welders expect.
