Industrial Gaskets manufactures Preformed Graphite Ring Sets or as commonly known, Valve Packing Ring Sets.
Preformed Graphite Ring Packing Sets incorporate ultrahigh purity flexible graphite and ultrahigh purity graphite yarns to ensure low contaminant levels.
High density pre-formed graphite rings form the stack with Flexible Graphite Braided top and bottom sealing rings. These rings ensure compression of the middle sealing rings and will prevent any packing extrusion.
These packing sets provide maximum performance whether installed in a new valve or when repacking an installed valve.
Dimensions required for order/pricing are the Stack Height and number of rings in the stack.
