Twin Welding Hose Assembly
Product Overview
PASSION® Twin Welding Hose is designed for safe and reliable delivery of oxygen and LPG gases in welding, cutting, brazing, and metal fabrication applications.
The blue hose is dedicated to oxygen service and features EPDM rubber tube and cover for excellent weather, ozone, and abrasion resistance. The orange hose is specially designed for LPG transfer, utilizing a 100% virgin NBR inner tube combined with a 100% pure EPDM outer cover to ensure outstanding resistance to fuel gases while maintaining excellent outdoor durability.
Manufactured according to ISO 3821 and ARPM IP-7 requirements, each hose is reinforced with a high-strength polyester braided layer for stable pressure performance and long service life in demanding industrial environments.
Suitable for shipyards, construction sites, steel fabrication workshops, maintenance facilities, and metal manufacturing industries.
