The Ø4 4.4m 1.2-1.6mm bronze neck Teflon sleeve is a component designed to efficiently guide welding wire. Thanks to the Teflon material, it ensures smooth wire flow and minimizes friction, which contributes to the stability of the welding process. The bronze neck enhances resistance to mechanical damage and heat, and the 4.4m length makes it ideal for long-term use in demanding conditions.
