- Safety protection: Specifically designed for use in tight spaces, it offers enhanced safety for personnel and equipment. The unique cut-out opening, the latching mechanism, and the upper-ring design provide greater flexibility during use. - Advanced flame retardant performance: Suitable for various high-temperature welding environments with temperature resistance up to 1800 F (1000 C). It delivers effective fire protection and does not melt, using high-quality flame-retardant materials to reduce fire risks. - Durable construction: 3-4 mm thick carbon felt material and a thickened shell deliver long-lasting durability, tear resistance and softness, while improving insulation and welding safety. - Optimized welding performance: Enables efficient welding in tight spaces through flexibility to fit pipes of different diameters. Ideal for copper pipes and other pipeline applications. - Practical applications: - Welding copper pipes in confined spaces such as wall cavities or utility rooms - On-site pipeline installation with varying pipe diameters in industrial settings - Welding in tight equipment enclosures or machinery with restricted access
