PW14-50 - 50ft Grade R Oxy-Acetylene Twin Hose 1/4 Inch

Industrial Grade R Twin Welding Hose - 50 Feet

The PW14-50 is a premium-quality Grade R twin welding hose designed to meet the rigorous demands of industrial fabrication, maintenance, and repair operations. Engineered specifically for oxygen and acetylene gas service, this hose assembly provides a reliable conduit for fuel and oxidizer gases in oxy-fuel cutting, welding, and heating applications. The hose features a robust rubber construction that balances flexibility with durability, ensuring it can withstand the abrasive environment of a busy workshop or job site while maintaining ease of handling.

With a length of 50 feet, this hose assembly significantly expands the operational radius of your welding station, allowing operators to reach workpieces that are distant from the gas cylinders without the need to frequently move heavy equipment. The 1/4-inch inner diameter is the industry standard for most manual cutting and welding torches, providing sufficient gas volume to support a stable flame and efficient heat output. The hose is clearly color-coded—green for oxygen and red for acetylene—to prevent cross-connection and ensure safety compliance.

It is important to note that Grade R hoses are specifically formulated for use with acetylene gas. The tube material is not oil-resistant and should not be used with propane, natural gas, or propylene, as these fuels can deteriorate the inner lining over time. For shops exclusively utilizing acetylene, the Grade R rating offers a cost-effective and safe solution. The assembly comes complete with standard B-size (9/16"-18) brass fittings, ensuring compatibility with the vast majority of regulators and torch handles on the market today.
