This model of a packing gland will allow you to train workers on the techniques and challenges associated with threading segmented ring packing onto a piston rod. Model will include 3 segmented packing sub-assemblies ( 2 radial cut rings, 1 tangential cut ring x3). Model shown is a 5 section gland, production models will be a 3 section gland. Comes with dummy piston rod and piston rod stand to enable horizontal assembly. Dimensions will be added to this listing once the prototype has been tested.
