This detailed guide outlines the process of assembling Teflon insulating sleeves with a coil shell for efficient tube bending. It includes specifications for tube bending blocks, including a G-10 material block with machined grooves. A rubber strip may be added to prevent slippage during bending. The protective cover bracket specifications, including dimensions and construction material, are detailed to ensure durability. The instructions highlight the importance of proper coupling brazing at coil assembly. Utilize adhesive solutions such as "Great Stuff" for optimal performance.
