STK G2 is constructed using a composite yarn manufacturedfrom high quality PAN fibres combined with pure Carbon fibres.The in-built lubrication and superior packing fibre properties ofthis composite yarn are further enhanced by a thorough graphiteimpregnation and high temperature lubricants.STK G2 is a soft, conformable packing, with a square, interbraidedlattice construction, which creates improved sealingcontact with less gland pressure. The self-lubricating PAN fibre,reinforced with Carbon and heavily coated and impregnatedwith graphite lubricants, practically eliminates shaft scoring.STK G2 gives extended packing life, with reduced shaft wearand gland maintenance
