OVERVIEW

Reliable Oxy-Acetylene Delivery for Professional Shops

Ensure safe and efficient gas delivery with this premium Grade R Twin Welding Hose. Designed specifically for oxy-acetylene applications, this hose assembly is an essential component for fabricators, metalworkers, and maintenance professionals who demand reliability in their equipment. The hose features a distinct color-coded system—green for oxygen and red for acetylene—to prevent cross-connection and ensure safety protocols are easily followed in busy shop environments.

With a generous 3/8-inch inner diameter, this hose is engineered to handle higher flow rates than standard 1/4-inch lines. This makes it particularly suitable for heavy-duty applications, such as operating large cutting torches, rosebud heating tips, or gouging equipment where gas volume is critical for performance. The 12.5-foot length is strategically sized for bench work, training booths, or stationary manifold systems where long, unruly hoses would only create clutter and safety hazards.

Constructed with a flame and oil-resistant cover, this Grade R hose stands up to the rigors of daily industrial use. While Grade R is specifically formulated for acetylene gas, it offers excellent resistance to abrasion and kinking, ensuring a long service life. The assembly comes ready to use with standard B-size fittings, allowing for immediate connection to your regulators and torch handles without the need for additional adapters or crimping tools.

FAQ

Grade R hose is designed specifically for use with acetylene gas only. Grade T hose features a neoprene liner that makes it compatible with all fuel gases, including propane, natural gas, and propylene, in addition to acetylene.

No, this is a Grade R hose. Using propane or other petroleum-based fuel gases with Grade R hose can cause the inner tube to rot and degrade, leading to dangerous leaks. You must use Grade T hose for propane.

This hose comes with standard B-size fittings, which are 9/16"-18 threads. The oxygen fitting has right-hand threads, and the acetylene fitting has left-hand threads (indicated by a notch on the nut).

A 3/8 inch hose has a larger internal diameter, allowing for greater gas flow. This is necessary for heavy-duty applications, such as using large heating tips or cutting very thick steel, where a 1/4 inch hose might restrict flow.

12.5 ft is a shorter length, often used for bench work or situations where the gas cylinders are very close to the work area. Standard lengths are typically 25 ft or 50 ft, but the shorter length helps reduce clutter.

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

No, this product is the hose assembly only. Flashback arrestors are sold separately and are highly recommended for safety.
