ITK® style 305 is Pure Graphite in the ribbon tape form, It is self-lubricating , low friction, high purity, ribbon tape without any filters, binders, resins, oil or grease which could possible leave the packing and reduce its volume or contaminate the process media. It is ideally suited for high temperature and pressure applications, This packing is non-hardening and dimensionally stable and impervious to gases and fluids. ITK® style 305 is cut from flexible graphite sheet with carbon content no less than 99% in rolls, as the filler for spiral wound gasket in situ pumps and valve gland packing.

ITK® style 308 is a self-lubricating, pre compressed die formed rings constructed from pure graphite ribbon tape without any filters, binders or resins. The rings are designed to produce and accurate specific density for compression resistance, elasticity and retention of size and shape. All of which are necessary to provide the best possible valve sealing performance. In ITK® style 308 die formed rings the mechanical pressure is exerted over a larger areas, which greatly increase shaft sleeve life. ITK® style 308 can be supplied to required size for ease of fitting.

ITK® style 304 is constructed from pure expanded graphite yarn with excellent carbon content. Being pure graphite they have excellent chemical resistance, thermal conductive and can be used n extreme temperature and pressure conditions. ITK® style 306 is reinforced with Wire mesh (Inconel wire) for suitability to high temperature and pressure. Both ITK® style 304 and ITK® style 306 can be used as die formed rings as per requirements.
