Description

Twin Welding Hose – R/T Grade, ENISO 3821, for Oxygen & Fuel Gas

Size Range: 1/4" / 5/16" / 3/8" | Working Pressure: 300 PSI (20 bar) | Temperature Range: -30°C to +90°C (-22°F to +194°F)

The Twin Welding Hose is a high-quality, flexible dual-line hose designed for safe and reliable oxygen and fuel gas delivery in welding, cutting, and related processes. It features separate color-coded lines – one for oxygen (Green/Blue) and one for fuel gas (Red) – to prevent cross-connection and ensure workplace safety.

This hose is widely used in industrial welding, construction sites, shipbuilding, and metal fabrication where performance, safety, and durability are required.

Key Features

  • Durable Inner Tube: SBR synthetic rubber provides excellent resistance to oxygen and fuel gas, ensuring safe and stable gas transmission.

  • High-Strength Textile Reinforcement: High-tensile polyester fiber braid delivers flexibility and consistent pressure performance.

  • Protective Outer Cover: UV-, abrasion-, and weather-resistant EPDM synthetic rubber cover ensures long service life in harsh working conditions.

  • Wide Temperature Range: Operates reliably from -30°C to +90°C (-22°F to +194°F) for versatile applications.

  • Grade Options Available: Available in R Grade (acetylene专用) or T Grade (compatible with LPG, propane, natural gas, hydrogen, and other fuel gases).

  • Industry Standards: Meets ENISO 3821 and RMA IP-7 quality standards for safety and reliability.

  • Flexible Color Options: Available in Red/Green, Red/Blue, Blue/Orange, or customizable to suit your identification requirements.

  • Versatile Connector Options: Available with brass fittings in Metric (M16x1.5), British (G3/8-19N), American (G9/16-18N), and Australian (5/8-18N) thread systems.

Applications

Commonly used for:

  • Oxygen and acetylene welding and cutting

  • Arc welding with shielding gas

  • Oxygen and hydrogen/coal gas/carbon gas transmission

  • Shipbuilding, construction, and metal fabrication

  • Industrial and workshop gas supply systems
