ZB series welding nipples have been designed for the assembling of GW descaling tips onto main manifolds. The accurately machined dove-tail profile assures for precise alignment of the nozzle tip with respect to the axis of the spray manifold. The contact area with the nozzle tip shows a surface machined to an accurate finish to prevent leakage between nipple and nozzle tip.ZB nipples are available in three length values to match different dimensional requirements.
