770131 - Grade T Twin Welding Hose 1/4" x 25' with B-Fittings

Industrial Grade T Twin Welding Hose

The Hobart 770131 is a premium Grade T Twin Welding Hose designed to meet the rigorous demands of industrial welding and cutting applications. Distinguished by its superior chemical resistance, Grade T hose is the required standard for use with alternate fuel gases such as propane, natural gas, and propylene, while maintaining full compatibility with acetylene. This versatility makes it an essential component for workshops that utilize multiple fuel sources or require a higher safety margin against oil and flame exposure.

Constructed with a high-quality synthetic rubber tube and cover, this hose offers excellent resistance to oil, grease, and abrasion, significantly extending its service life in harsh shop environments. The 1/4-inch inner diameter ensures sufficient flow rates for most standard cutting torches and welding handles, supporting a stable flame and consistent performance. The hose is reinforced to withstand working pressures up to 200 PSI, providing a robust safety factor during operation.

This assembly comes pre-fitted with standard "B" size (9/16" - 18) brass fittings, ensuring immediate compatibility with the vast majority of regulators and torches on the market. The fittings are crimped securely to prevent leaks and ensure a reliable connection. The twin-line design bonds the oxygen (green) and fuel (red) lines together to prevent tangling while maintaining organization on the shop floor. Whether for fabrication, maintenance, or repair, the Hobart 770131 delivers the reliability and safety compliance required by professional standards.
