Our twin welding hose is a premium dual-line rubber hose designed for oxy-acetylene welding, cutting, and allied gas applications. Each hose in the pair is color-coded—red for acetylene, green/blue for oxygen—and constructed with a heat-resisting EPDM inner tube, reinforced with spiral polyester yarn, and protected with a smooth synthetic rubber cover. Compared to braided hoses, this twin hose offers greater flexibility, easier handling, and durability for industrial and workshop environments.
Rubber Twin Welding Hose is a premium welding hose, Green hose for Oxyen Red hose for Acetylene, Heat resistant EPDM tube and cover 2 spiral polyester yarn reinforcement, more flexible than braid reinforced hose, easier to coil and handle, Coiled coupled assemblies are available in 25 and 50 foot lengths. It can be used with most current fuel gases, including acetylene, propane, and MAPP gas. The welding twin hose Grade T is a high-quality welding hose with an oil and flame-resistant tube and cover. It’s flexible to work under a wide range of temperature ranges, making the hose durable for long-term use. Unlike other hose sets that easily leak or crack, the twin welding hoses have superior kink, crack, abrasion, and weather resistance, ensuring safety in use.
Color-coded dual lines — simplifies gas identification and safety
Heat-resistant EPDM tube — handles high-temperature gas exposure
Spiral polyester reinforcement — balances flexibility and strength
Abrasion & ozone resistant cover — suitable for harsh environments
Lightweight & flexible — easier to coil, route, and store
Long service life — tested for extended cycles without leakage
Custom lengths & assemblies — available in 25 ft, 50 ft, with fittings

A: A twin welding hose carries two gas lines—oxygen and fuel gas—in one unit, reducing clutter and simplifying connections in welding setups.
A: This hose supports oxygen, acetylene, propane, natural gas, CO₂, nitrogen, and other welding-compatible gases.
A: Common lengths are 25 ft and 50 ft. Custom lengths are available upon requirement.
A: –32 °C to +80 °C is typical. For higher temps or special environments, customization is necessary.
A: The dual lines are color-coded (red for fuel gas, green/blue for oxygen) to ensure safe connection and usage.
A: Yes—its abrasion- and ozone-resistant cover makes it suitable for outdoor or portable welding applications.
